7"he,w li.sts represent the membership at the time em'h Committee was balloted on the text t~" this edition. Since that time, changes in the membership mt 9, have occurred. A key to class!fication.s is fmmd at the

front ~" this book.

This portion of the Technical Committee Report of the Automatic Sprinkler Systems Committee is presented for adoption in 3 parts.

The Report was prepared by the: • Technical Correlating Committee on Automatic Sprinkler

Systems (AUT-AAC) • Technical Committee on Hanging and Bracing of Water-Based

Fire Protection Systems (AUT-HBS) • Technical Committee on Residential Sprinkler Systems (AUT-

RSS) • Technical Committee on Sprinkler System Discharge Criteria

(AUT-SSD) • Technical Committee on Sprinkler System Installation Criteria

(AUT-SSI)

Part I of this Report was prepared by the Automatic Sprinkler Systems Committee, and documents its action on the comments received on its Report on Proposals on NFPA 13-1996, Standard for the Installation of Sprinkler Systems, as published in tile Report on Proposals for the 1999 Spring (May) Meeting.

Part I of this Report on Comments has been submitted to letter ballot of the individual Technical Committees. The results of the balloting, after circulation of any negative votes, can be found in the report.

In addition, pertaining to the Technical Committee on Sprinkler System Discharge Criteria (AUT-SSD), Mr. Miller abstained fi-om voting as he was not at the meeting, and Mr. Fleming and MR'. Keeping provided the following remarks regarding the report:

Fleming: "It was voted to change the metric equivalents of all design densities to ram/rain, which is the same as L /min /m ~. The enUy in Table A-7-3.3.1 should read:

gpm/ft -° mm/min 41

Last two sentences of 6-4.6.3 should be at the end of 6-4.6.1 instead and rephrased as follows: 'Wire used for restraint of branch lines shall be located within 2 ft (610 mm) of a hanger, and the hanger closest to a wire restraint shall be of a type that resists upward movement of the branch line,'

In the new Figure A~o-l.l, the label 'Retrofit wraparotmd U-hook devices' should be changed to 'Clip-on wraparound U-hook devices' since the word retrofit could imply it is not to be used on new installations."

Keeping: "I agree with Mr. Fleming, the committee voted to change the metric equivalents for all densities to ram/rain."

Part I of this Report on Comments which includes Technical Correlating Committee Comments 13-20a (Log #CC504), 13-83a (Log #CC500), 13-134a (Log #CC501), 13-167a (Log #CC502), and 13-225a (Log #CC503) has also been submitted to letter ballot of the Technical Correlating Committee on Automatic Sprinkler Systems, which consists of 18 voting members; of whom 17 voted affirmatively, with the exception of Mr.Oliver who did not return his ballot, and Mr. Schirmer who voted negatively on Comment 13-19a (Log #CC200).

Mr. Schirmer voted negatively on Comment 13-19a (Log #CC200 with the following remarks:

"I agree with the comment itself and have voted affirmatively on it as a member of the Discharge Committee. I am voting negatively here as the timing of this ballot violates due process as well as common sense. This was sent (if mailed immediately after typing) on February 22. Received Februat~¢ 26. Due March 4. This is ridiculous. Note the transmittal letter required retur~ by February 26. The ballot indicates March 4."

555

Mr. Huggins voted affirmatively with the following remarks on C o m m e n t 13-167a (Log #CC502):

"The requ i rement for QR heads througl~out the c o m p a r t m e n t was supposed to be added to Chapter 5 as part o f installation requirements . It does not belong unde r 7-2.3.2.4."

Mr. Noble voted affirmatively with the following remarks on C o m m e n t 13-167a (Log #CC502):

" C o m m e n t 13-167a (Log # CC502) [7-2.3.2.4] conta ins what I believe are typographical errors. T he second sen tence within the second paragraph should read ' T he m a x i m u m ceil ing he igh t ' no t 'a m a x i m m n ceiling height . ' Also, the except ion should read 'Where circumstances. . . ' no t 'The re c i rcumstances ' . "

Part II o f this Report on C o m m e n t s was prepared by the Technical Commi t t ee on Resident ial Sprinkler Systems, and d o c u m e n t s its action on the c o m m e n t s received on its Repor t on Proposals on NFPA 13D-1996, S tandard for the Instal lat ion o f Sprinkler Systems in One- and Two-Family Dwellings and Manufactured H o m e s , as publ ished in tire Report on Proposals for the 1999 Annual Meeting.

Par t II of this Report on C o m m e n t s has been submi t ted to letter" ballot o f the Technical Commi t t ee on Resident ial Sprinkler Systems, which consists of 19 voting members . The results o f tire balloting, after circulation of any negative votes, can be found in the report.

Par t II of this Report on C o m m e n t s has also been submi t ted to letter ballot of the Technical Correlating Committee on Automatic Sprinkler Systems, which consists o f 18 voting members ; o f whom 14 voted affirmatively with the exception of Mr. Oliver who did no t return his ballot, and 3 who voted negatively after circulat ion o f negative ballots (Messrs. Fleming, Stephens , and Walsh).

Mr. F leming voted negatively stating: "There are two issues which have resulted in my negative ballot.

In C o m m e n t 13D-5 (Log #CC1), the commi t tee proposes , for the first time, to allow any and all types o f piping to be connec t ed to a spr inkler system. To allow non-listed non-metall ic pipe m e a n s there will be no restrictions on thermal protect ion for d rops to p l u m b i n g fixtures. This can easily compromi se the spr inkler protect ion.

"The Technical Correlat ing Commi t tee has also failed to address tire issues raised in C o m m e n t 13D-10 (Log #10) regarding the need for a system flow alarm. The Technical Correlat ing Commi t tee admits a conflict with NFPA 72 but has chosen to appoin t a liaison to work on this p rob l em rather than resolve it prior to issuance of a new edition of NFPA 13D."

Mr'. S tephens voted negatively stating: "I considered it necessary to vote negatively as I do not cons ider

that one issue has not been satisfactorily resolved. C o m m e n t 13D- 5 (Log #CC1) allows p ip ing to p l u m b i n g fixtures to comply with local p l u m b i n g and heal th authori ty requ i rements and does not r-equire this piping to be listed. Where the integrity o f tire sprinkler system is d e p e n d e n t on the domest ic water p lumbing systems, then the domest ic water p lumb ing should either" be of equivalent pressure s t rength and fire resistance or manda to ly measures should be imposed to prevent water flow into tire domest ic water system upon operat ion of a sprinkler."

Mr. Walsh voted negatively stating: "I concur with the posit ions taken by Mr. Fleming and Mr.

S tephens on C o m m e n t 13D-5 (Log #CC1)."

Par t III of this Report on C o m m e n t s was prepared by the Technical Commi t t ee on Resident ial Sprinkler Systems, and d o c u m e n t s its action on the c o m m e n t s received on its Report on Proposals on NFPA 13R-1996, S tandard for the Installation of Sprinkler Systems in Residential Occupanc ies up to and Including Four Stories in Height , as publ ished in the Report on Proposals for the 1999 Annua l Meeting.

Part II1 o f this Report on C o m m e n t s has been submi t ted to letter ballot of the Techmca l Commi t t e e on Residential Sprinkler Systems, which consists o f 19 voting members . The results o f the balloting, after circulation o f any negative votes, can be found in the report.

Par t III o f this Report on C o m m e n t s has also been submit ted to letter ballot o f the Technical Correlat ing Commi t t ee on Automatic Sprinkler Systems, which consists o f 18 voting members ; o f whom 17 voted affirmatively with the except ion of Mr. Oliver who did not re turn his ballot.

S U B S T A N T I A T I O N : Not all buildings or properties that have a need for underg round :[]re protection vcater mains are equipped with automatic sprinkler systems. There is a need for NFPA Standard No. 24 ~ts a stand alone document for use on tllese properties. Presently, tile wording from NFPA Standard No. 24 is being force fit into this expanded document. Some of the material presently in NFPA 24 is ,rot being incorporated because it .hviously does not belorg. ()tber material is awkward and is being forced into where it does not belong. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The Committee believes that the underground main is an integral part of tile sprinkler systeul akM its install,ttion should bt included in NFPA 13. Additionally, wllere mldergrourid mains will be installed for pri~tte fire service purposes, tills will be ad:lressed by NFPA 14, Standard for tl~e Installation of Standpipe and Hose Systems.

COMMENT ON PROPOSAL NO: 1.9-1 RECOMMENDATION: Retain the nominal orifice size inh,rmation fi~r this standard cycle to help with tile transition to ,rely listing tile nominal K-thctors. S U B S T A N T I A T I O N : Tiffs will help the users make die transition from one orifice size identification method to another. (kmlplete tile proposed action at tile next edition of tile standard. COMMITTEE ACTION: Accept ill Principle. Add appet)dix material to TaMe 3-2.3.1 of the Preprint to read as f,)lh,ws:

Nominal K-factor Nominal Orifice Size

1.4 1/4 (6.4 ram) 1.9 5 /16 (8.0 ram) 2)'I 3 /8 (9.5 mm) 4.2 7/16 (11.0 mm) 5.6 1/2 (12.7 nun) ,%0 17/32 (13.5 toni)

S U B S T A N T I A T I O N : Material on pri~tte fire service mains does not belong in a sprinkler installation standard. For new sprinkler installations, the underg round is typically installed by different people than the sprinkler piping, l ag ree with Mr. Keeping's comment about the need for maintaining NFPA 24. NFPA 24 should be maintained and if that is the case, then there is no need to clutter up NFPA 13.

It is not practical for me or tile public to call out each specific reference to NFPA 24 material in tile proposed new Chapter 1 of NFPA 13. COMMITTEE ACTION: Reject.

1.9, - 5 - ([1-1 Scope]): Reject SUBMITTER: Richard E. Thonnings, Aineriran hlsuranre Services Group, Inc. COMMENT O N PROPOSAL NO: IN2 RECOMMENDATION: The scope of NFPA 13 shouM be cllanged to exclude design of automatic fire sprinkler systems. All design-related material should be contained in a separate document. NFPA 13 should limit its scope to installation. S U B S T A N T I A T I O N : Installation and design are two distinct areas and deserve separate docnlnents. Also, tile amount of material now contained in the "partially revised" NFPA 13 is so large that it will become cumbersome to use. Tile evohition of performance-based standards also makes it ad~rmtage,,us to place design topics in a document separate fl'om installation requirements. Two individual docmnents will make it easier to use and update in the fiuure.

h is not practic&l for me or the public to call out eacll specific reference to design-related material in tile proposed new Chapter 1 of NFPA 13. NFPA h:Ls sadly chosen an awkward change process for tile 1~333c~ edition of NFPA 13 which seems designed to hinder substantial public input. The proposed 1999 edit i .n is obviously more tll;m a "partial revision." COMMITTEE ACTION: Reiect. COMMITTEE STATEMENT: NFI'A 13 ll:Ls always addressed sprinkler system design for Light hazard, ordinary hazard, .uld extra l/az:trd occupancies. Tile [,roposed changes expand tile scope to include tile design for other applicati,ms -I sprinkler systems. Tile (;omufittee also believes that separating tile design and instMl,ttion requirenlents would confuse tile end user. NUMBER OF COMMITTEE MEMBERS ELIGIBLE T O VOTE: 26 VOTE ON COMMITTEE ACTION:

Furthermore, once tile new marking system of Proposal 13-24 is in place, such identification ;ts proposed (in 13-22) will be in place unless manufacturers decide to place such markings on the thernlal element. If that is done, it will defeat the intent of both Pr, qu~sals 13-22 and 1%24.

COMMITTEE ACTION: Reject. COMMITTF.£ STATEMENT: The submitter has not provided adequate technical data substantiating that significant nmnbers of sprinklers are being replaced with sprinklers of incorrect temperature ratings. The correct sprinkler temperature rating is a t rac t ion of the building and environment, not file sprinkler itself. The correct temperature sprinkler to be nsed should be readily apparent widmut looking to tile previous installed sprinkler. The issue regarding the marking of sprinklers to identify different orifice sizes, deflector characteristics, and therm~d sensitivity is a different issue pertaining to both new installations and replacement.

S U B S T A N T I A T I O N : Tile purpose of requir ing three proper types of sprinkler s toppers in every sprinkler cat)inca is to reduce all(t prevent alnnecessary and sonletimes extrenlc sprinkler system water damage to a strllCtHl'e al]d its c(intenls. Tile purpose is also t,, rrdtn-e fire depa r t men t liability in s i tuat ions where a small fire has been ex t inguished hv the sprinkler system. Sprinkler s toppers can be installed by life personnel f reeing t hem for o ther emergency responses while technically qualif ied sprinkler ind~.lstry p e r s . n n e l can properly restore tile sprinkler system, including feplacillg opened sprinkler heads, reset t ing the clapper ~tlve, dra in ing and testing the s}~tem.

"l"he c~st of requi r ing tllree sprinkler s toppers be kept in every sprinkler cabinet is minimal when compared to tile mil l ions of d~ilars tha'~ cmiM he s;wed ~wer a period of t ime.

Where recessed, sidewall, or eollcealed 1leads are conce rned there are nniversal style s toppers availaMe (see copy provided) at a cost of about thirty five dollars.

The Commit tee ' s concern that the possibility of a s topper being used mid not renloved seems like a valid reason for rejection of this p r . tmsa l until you look at tile fact that in file State of Hawaii lhe r equ i r emen t of three sprinkler s toppers be kept in every sprinkler caMnet has been ill effect for over twelve years and there has never been a single incidence of violation of this code.

Where insert fittings are used to connect the last sprinkler on a branch line, the 3 / 4 inch fitting can reduce the pressure available at the sprinkler and this needs to be accounted for. Additionally, current hydranlic calculation procedures do not consider friction losses through straight through fittings. This may not be appropriate w6ere 's,/4 inch insert fittings are used. A change in the hydraulic calculation procedures may also be required. More data needs to be deve loped in regard to these issues.

Listed flexible couplings shall he visually identifiable and differentiated from nonflexible couplings by cme of tile following Ineth ods:

a. a cas t ing h ie or pint le . b. listed flexible c(,uplings (only} shall t)e painted red in color.

SUBSTANTIATION: The standarcl identifies specific locations where flexible couplings are required in areas subject to damage tYom earthquakes and requires additional braces where flexible conplings are used on cross mains. The flexible couplings are critic~d to s~tem integrity in earthquake areas. (;urrently, there is no way fiJr the installer or inspectors (AHJ) t . visually verity which couplings are used. The option of color code is similar to sprinkler head temperature identification. COMMITTEE ACTION: Reiect. COMMITTEE STATEMENT: Tlle Committee is ot the opinion that the model numl)er on tile coupling suflY:iently identifies a coupling :ts either flexible of rigid. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 26 VOTE ON COMMITTEE ACTION:


EXPLANATION OF NEGATIVE: CAPI IT(): I disagree with tile Committee Statement that the

model number on the coupling sufficiently identifies a coupling as either flexible or rigid to an inspector, when file coupling is installed 20 ft or 30 ft in the air.

The standard identifies locations where high temperature or other than normal temperature rated sprinklers mnst be installed for proper protection and those sprinklers are clearly identifiable to inspectors by a color code.

Similarly, file standard identifies critical locations where flexible couplings are required. We nmst require those couplings to be eztsily identifiable if we expect them to be installed in fl]eir required locations. Inspectors cannot be expected to use lift equipment or ladders and flasldights to verily this critical element of the installation.

MOWER: I agree with tile submitter's substantiation. In buildings such as strip malls and large spee. warehouses, occupancies 0lay be covered by more than one system. A fire occurring in the area between the two systems becomes a tactical nightmare for responding fire departn)ents who must determine which system to supply, or worse, to have to supply both systems independently.

Exception: "Raised lips at the end of listed and approved threaded lightwall pipe which do not exceed .050 inch (1.27 ram) shall not be considered as burrs or fins and shall be permitted." SUBSTANTIATION: 1. The Conmlittee Statement does not detail "the quality assurance measures in installation" with which tile committee is concerned. However, conversations in various arenas have unearthed what some of the issues may be.

2. The term burrs and fins in 2-5.6 provides fi)r a wide interpretation by the AHJ's. When lightwall pipe is threaded a small lip sometimes remains, instead of burrs and firm, which one may envision :LS a section of steel that may break off or impede flow in some way. This is merely a slight lip and dislodgement or flow impediment is not an issue and will never occur.

3. If there is a concern tiffs lip could cause worker injury, tile record supports this ~s unwarranted. As noted in the proposal, installations having these lips have been made without injuries. Some have beet] disassembled and rehandled due to the AHJ i t J t e rp re ta t ion it was a "bl l r r or fin" tha t nlay canse a flow loss.

Accept Proposal 13-50 (Log#160) . S U B S T A N T I A T I O N : T h e Commit tee ' s substant ia t ion fails to consider the points made in the proposal, focusing only on a reference to trip t imes and delivery times. If delivery t ime is the critic:d factor, what is this time? Is it 1 minu te (for nong r idded systems over 750 gallons)? Is it 3 minu tes (NFPA 13 Handbook ,

~ age 139)? ()r, is there no limit (,as long as system size is less than 50 gallons)? Wha t if a g r idded system less fllan 750 gallons could

p roduce pe r fo rmance comparable to a non-gr idded system less than 750 gMlons? In o ther words, what if the gr idded system could deliver water in 3 minutes? It seems this would be comparable in per formance , especi:dly in view of the Handbook connnentary .

The proposal notes the lack of a design basis for existing requi rements , conflicts in existing requi rements , and conflict ing informat ion provided in the cur ren t NFPA 13 Handbook. None of these issues were addressed by the commit tee .

This proposal establishes a m a x i m u m trip t ime and a m a x i m u m delivery time. Both of these are necessary to use a pe r fo rmance m e t h o d for design. By a d d i n g p e r f o r m a n c e language, certain - prohib i ted systems, such as gr idded systems, could be used.

COMMITTEE STATEMENT: The Technical Conmti t tee agrees that more specific pe r fo rmance criteria shou ld be provided.

NFPA 13 shou ld not require quick-opening devices but ra ther provide criteria if they are insudled. NFPA 13 currently reqnires a quick-opening device on a 600 gallon dry pipe system with a delivery t ime of 65 seconds but does not require one on a 400 gallon dry pipe system with a delivery t imes of 8 minutes; this seems to contradict the Comlrdttee 's su t t emen t tha t delivery t ime is the critical factor.

1"4- 55 - ([Chapter 5]): Accept in Principle SUBMITTER: Donald B. Pounder, Grinnell C, orp. COMMENT ON PROPOSAL NO: 13-209a RECOMMENDATION: Revise NFPA 13 to incorporate the requirements for ESFR sprinklers having a nominal K-factor of 25.

Revise text as follows: 5-11.4.2 (13-4-11.4.2) Deflector ()rientation. IJeflectors of

sprinklers shall be aligned parallel to ceiling or roofs. Penclent sprinklers shall be positioned so that deflectors are a maximum 14 in. (360 ram) for sprinklers havin~ a nominal K-factor of 13.5 - 14.5 or 18 in. (460 mm~ for snrinklers bavin~ a nominal K-factor of 24.2 - 26.2 and a minimum of 6 in. (150 mmi below the ceiling. SUBSTANTIATION: This ( :omment is a result of Comment 1 3- 160 (Log #127) which w:Ls submitted to the Technical Committee ~tl Sprinkler System Discharge Criteria. Section 5-11.4.2 of the Preprint pertains to installation requirements and is more approlwiately addressed by the TechnicM ( 'ommittee on Sprinkler ,System Installation Criteria. Therefore, Comment 13-160 (Log #127) was split into two comments with the installation requirements for the K-25 sprinkler addressed here.

1. Approved ESFR sprinklers having a nominal K-factor of 25.2 have been a~tilable for almost a year. There has been considerable interest in these sprinklers and dleir use should be detailed in this standard.

2. By incorporating information on ESFR sprinklers having 26 K-factors now, the need to issue a TIA will be avoided. This is an important change which should be incorporated in-cycle.

3. An extensive series of fire tests h,'~s been conducted at I Inderwriters Laboratories using the Grinnell Model ESFR-25 sprinkler to establish the minimum design pressures fiJr the commodities for which this sprinkler will be Listed. A copy of their report is attached. It is noted th.tt in a comparative test of ESFR sprinklers having a nominal K-factor of 14.0 and those having a nominal K-lictor of 25.2, the higher K-factor sprinklers demonstrated superior performance. It is also tinted that the pressures which are proposed are intended to provide tl~e santo or slightly higher densities fi)r ESFR's having K-t, tctors of 25 as compared to ESFR's having K-factors of 14.

4. The wording of Section 7-6.5.2 (13-5.3.5.2) h:Lq been changed to delete reference to the appendix Table A-7.6.5 since information in that table has already been included in tile non-

~ )pendix tables dealing with ESFR sprinklers. OMMITTEE ACTION: Accept in Principle. Accept the submitter 's proposed Section 5-11.4.2 with the

following revisions: 5-1 1.4.2 Deflector ()rientation. Deflectors of sprinklers shall be

aligned par:did to ceiling or roo£s. Pendent sprinklers shall be

~ ositioned so that deflectors are a m,tximum 14 in. (360 ram) elow the ceiling for sprinklers having a nominal K-factor of 14. or

18 in. (460 ram) below the ceiling tbr sprinklers having a nominal K-factor of 25.2 and a minimum of 6 in. (150 ram) below the ceiling. COMMITTEE STATEMENT: The changes made by tile G'ommittee are considered editorial in nature. Sprinklers will now be identified according to nominal K-factors and a K-/actor range will no longer be referenced in the standard.

This action corrects an o m i ~ i o n ~ ' t h e TCC bel ieves that a distinction needs to be made between those K-11 sprinklers intended for s torage applications and those that are not.

EXPLANATION OF NEGATIVE: ISMAN: We are conce rned tha t tire Commit tee h:ts omit ted the

requirement that sprinklers in t ended for s torage applicat ions be listed for storage applic~ttions. We have had the problem in the past that sprinklers with orifice sizes greater than K=8.0 h:we got ten listed when there w ~ a problem us ing t hem for storage appli~Tltions. Special listing procedures were necessary for these big orifice sprinklers that were requi red by the storage s tandards (NFPA 231 and 231C). While some of the listing labs migh t subject big orifice sprinklers to these special tests in order to allow them to be listed at all, there is no manda t e f rom NFPA 13 to dd suclL and o ther labs may not follow the procedure ant icipated by

the Commit tee . It is impor tan t for the Conmfit tee to make it clear to die ktbs what t rey want :Ls part of the listing process. By el iminat ing this requ i rement , we have mudd ied the water, not made it clear.

TESTA: W h e n C o m m e n t 1%59 (Log #201) wàs first in t roduced at the R()C meet ing , considerable coIwersation took j)lace. To limit conversatiorL I àsked the Chair to appoin t a special task force to convene to establish p roper verbiage and submi t a written repor t for this impor tan t rule change.

A few hours later the spokesperson read the above. My first c o m m e n t wàs, "Does any firm o ther dmn Central have large K- factor spray sprinklers? The reply was "many." As a result. I was in agreement .

As of today, November 30, upon review of IJL Fire Protection Equ ipmen t Directory 1998. indicates six (6) manufac tu re r s have l is tedK-I 1 spray sprinklers, arid one manufac tu re r has a listed K-14 and one h:L~ a listed K-I 7.

My negative ballot mus t be processed knowing a "Restraint of Trade" exists; therefore, I s trongly r e c o m m e n d ( ; ommeu t 1%15 (Log #201) be re tu rned to Comini t tee for inclusion in die next NFPA 13 Standard change schedu led for the year 2001 or later. COMMENT ON AFFIRMATIVE:

COMMITTEE STATEMENT: 1. Tile changes to tile subntitter's

~ roposed language are considered editorial, Also see item four elow. 2. The Committee added appendix language to more clearly

indicate their intent with regard to isolated obstructions. 3. Tile renmnber ing is considered an editorial change. Tile

section was revised to indicate file committee's intent tbat sprinklers installed nnderneath open grate flooring are to be ESFR sprinklers that ,are shielded from overhead discharge. The use of other types of sprinklers is not permitted.

4. Tile Committee believes that die wording proposed by the snbmitter for Section 5-11.5.3.2 is more appropriately located as an exception for the requirements concerning sprinkler spacing and area of coverage.

5. Appendix materkd was added to more dearly indicate the new exceptions. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 26 VOTE ON COMMITTEE ACTION:


EXPLANATION OF NEGATIVE: KEEPING: Tile Committee Action ,as printed bere strikes out the

second sentence in Section 5-11.5.3.2. This action is contrary to my notes. I was under the understanding that this text v~,Ls to be included. In fact, 1 have no memory of any discussion on this matter. I believe dae Committee's wishes <'ire not properly documented here ,and dlat die text should be returned. COMMENT ON AFFIRMATIVE:

LINDER: The Committee Action in Item 4 is incomplete. Tile exception should read: "It shall be permitted to deviate from the maximum sprinkler spacing to eliminate obstructions created by trusses and bar joists by moving a sprinkler along the branch line a maximum of 1 ft f rom its allowable spacing provided coverage for d3at sprinkler does not exceed 110 sq ft ~md the average spacing for the moved sprinkler and tile adjacent sprinkler do not exceed 100 sq ft. Adjacent branch lines sh~dl m~dntain the same 13attern. In no case shall the distance between sprinklers exceed 12 ft."

WALSH: The exceptions to 5-11.3.1 and 5-11.2.2 are incomplete. My notes show tbat the following should be added:

"Sprinkler does not exceed 110 sq ft and average spacing fi�r tile moved sprinkler and the adjacent sprinklers on the s:une line pipe does riot exceed 100 sq ft. Adjacent brmach lines shall mairltairi tile same pat tern. In no instance shall 12 ft be exceeded."

In 5-11.5.3.1 die word "springs" should be "sprigs."

COMMENT ON PROPOSAL NO: 13.170 RECOMMENDATION: Accept Proposal 13.170 (Log #119) ;ts written in this r enumbered section. SUBSTANTIATION: Return bends for ESFR sprinklers are impossible to install due to their requirement to be within 14 in. of the ceiling. Tile large orifice will allow any sediment to clear once tile sprinkler h~Ls opened. The screens and strainers required will not allow larger obstructions into tile piping. COMMITTEE ACTION: Reject.

The Tedmical Committee also notes that no new support ing material or data has been submitted. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 26 VOTE ON COMMITTEE ACTION:


EXPLANATION OF NEGATIVE: (;ERDES: I agree with p roponent that obstruction is unlikely

based on orifice size, screens and strainers. Return bends for ESFR sprinklers are unnecessary.

ISMAN: Our negative ballot is based on the knowledge that a fire pump taking suction from a pond or reservoir is already required to have two screens and a filter over the pump intake to protect it from getting objects into the pipe. This is better protection than many public water mains. FM has allowed these installations without return bends. FM knows more about ESFR sprinklers than anybody. Why should we be more stringent than FM?

SCHIRMER: Change to negative. I agree with Mr. Isman's statement.

5-14.1.1.13 .When using pressure regallating devices for sprinkler control valves, provide a drain outlet connection a n d / o r riser sized to allow flowing the regallating device at tile sprinkler s~tem demand. SUBSTANTIATION: Currendy NFPA 25 requires that these valves be "full flow tested" every "5 years," with results "compared to previous test results." Currently, NFPA 13 and 25 .tssumes that tile acceptance or previous 5 year results are always available, and NEPA 13 does not provide for a relatively easy alternative in the very possible event that they are not.

COMMENT ON PROPOSAL NO: 13-60 RECOMMENDATION: The text presently in NFPA No. 24 shotfld remain. SUBSTANTIATION: This is another example of the attempt to force fit two documents together. Outside PIVs can be very vahmble in controlling supplies to automatic sprinkler systems. The control valves at the base of a riser may be inaccessible under some fire conditions and underground valves may take considerable effort to reach them. In addition, quick action through PIVs can divert water supplies to viable sprinkler systems under trying conditions. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The Technical Committee does not believe that PIV's shonld be mandatory for connections from the private fire service main to the building. Section 5-14.1.1.1 of the Preprint currently requires control valves on all sources of water supply. Additionally, appendix material concerning PIV's has been added in Section A-5-14.1.3.

The references to 99 should also be general, not paragraph specific, e.g., "sprinkler systems in hyperbaric chambers shall conform to the requirements of NFPA 99, Chapter 19." SUBSTANTIATION: Extracting only bits and pieces of NFPA sprinkler requirements is confilsiug and will lead to errors ,'rod conflicts when NFPA 99 requirements change. COMMITTEE ACTION: Accept.

EXPLANATION OF NEGATIVE: KEEPIN(;: There is a conflict in die Comnfittee Actions of the

Discharge Commit tee and the Installation Committee on this matter. The Discharge Commit tee chose to extract the discharge related portions of NFPA 99, whereas here tire Installation Committee is accepting tire submitter 's proposal to only reference NFPA 99.

I believe dais matter needs to be addressed by die Technical Correlating Committee to bring these opposing actions into line.

SUBSTANTIATION: The incorpora t ion of excerpts fi 'om NFPA 409 is incomple te and may be nfisleading. In reality, NFPA 409 integrates several i n t e rdependen t fire protect ion approaches . In addit ion, any one of these approaches may itself have complex condit ions that govern the specific me thod of applicat ion of tha t approach. The sprinkler systems dtat are requi red by NFPA 409 are good examples of complex approaches that have requ i rements tha t vary according to occupancy, size, and o ther provided fire protect ion systems. T h e proposed excerpts provided in NFPA 13 describe only one of several condi t ions for the installation of sprinkler systems. The excerpts do not reflect the wide variations tha t NFPA 409 requires, front closed sprinkler systems to fo~mt water de luge sprinkler systems. The system requi red may vary based on condi t ion ,and size of housed aircraft, hanga r size, or the presence of supp lementa l u n d e r wing fire protect ion systems.

%Vith regard to h imging provisions, die criteria for hangers in concrete have been reorganized. The s t a t emen t that rod size is measu red at the root d iameter of the th read has been el iminated based o n recogni t ion of s tandard industry practice. Tile s t a tement that drive screws are permi t ted only in conjunc t ion with U-hook hangers has been changed to also permi t their use a.s part of a listed hange r assembly hav ing two points of a t tachment , which is cons idered eqnivalent. Coach screw rods have been added alongside lag screws in the r equ i r emen t s for m i n i m u m plank and beam thickness based on file equivalent na ture of their a t tachment . A general s t a t ement has been added to require trapeze hangers where needed to trimsfer loads to appropr ia te structural members . The h lmging criteria for nonmeud l i c pipe has been made m o re gener ic ,anticipating new types of special listed pipe. The criteria for lengdl of u n s u p p o r t e d a rmorers has been changed to reference "cumulative horizontal length" to clarify that it is no t abe ne t distance to the sprinkler in the plan view that is of consequence , bu t rather the total pipe length in the event of a swing joint . Sprig- nps and drops have been added to the u n s u p p o r t e d a rmorer criteria b ~ e d on the fact that the st~mdard does not cnrrently differentiate between these assemblies and sprinklers a t tached directly to the armorer . Tile basic criteria for hang ing of cross mains has been expmaded to apply to idl m,'-dns. A maximuul distance to hange r of 24 inches f rom tim centerl ine has been establ ished for risers or riser sections when they ,-ire provided with suppor t f rom horizont~d connect ions , such as the main at the top of the riser. This is cons idered a reasonable limit based on the need to prevent excessive m o m e n t s on tile horizontal pipin!~ and its fittings. The criteria for risers in high bays and vertical Shrifts have been clarified to not more than 25 ft between points of suppor t .

Widl regard to ear thquake protect ion provisions, criteria h~s been added to address the location of flexible couplings on risers in multi-story bui ldings where the piping serving the sprinkler system on each floor is no t near the ceiling. The proposal calls for the uppe r flexible coupl ing to be widfin 24 inches of the ceiling, bu t provides that an addit ional flexible coupl ing be provided on the vertical por t ion of the tie-in piping if the tie-in piping is below such point. This a r r a n g e m e n t is expected to permi t the riser assembly and vertical tie-in p ip ing to move as a uni t to accommo&t te expected story drift. The r equ i r emen t for flexible coupl ings near bui ld ing ~expansion jo in t s has been clarified with a 24-inch m a x i m u m distance, replacing the fo rmer "at or near" reference. A dist inction h,~s been made between requ i rements for "bracing" versus requ i rements for "restraint," which is considered a lesser degree of effort toward ho ld ing tile p iping in place. Where II-hooks are used to provide restrifint, dae r equ i r emen t h:ts been added dmt the legs be bent out at least 30 degrees f rom vertical, to match the criteria when such han~,ers are used its braces. Tile r equ i r emen t dmt swv, ty bracing be 'concentric" has been deleted based on the fact that brace a t t achmen t c o m p o n e n t s are required to be listed for dleir i n t ended use. A new rule hits been added that a longitudinal brace be no more than 40 ft f rom tile end of a run of main. Tiffs r equ i r emen t is needed in addi t ion to the 80 l'l m a x i m u m spacing to properly locate the bracing."

6-2.1.3" System piping shall be substantially suppor ted f rom bui lding s t r u c t u r a l c o n l p o n e n t s (see 6-1.1). The m e t h o d used to attach tile hange r to tile s tructure and tile load placed on the hange r should take into accoun t an}, limits imposed by the s tructure. For system mains h u n g to a single beam, joist, or pnrlin, provide the c~dculations requi red in 6-1.1 to prove the s t ructure capable of suppor t ing the arr~mgement. Design manual informat ion for p re -eng ineered s t ructures or odm r speciahy cons t ruc t ion material manufac tu re r s may be consul ted, if appropria te .

Cont inue the exception. Add to the appendix: A-6-2.1.3 System mains h u n g to a single beam, truss, or purlin

may ,affect tile structural integrity of the bui ld ing by in t roducing excessive loads not ant ic ipated in the bui ld ing design. Also, special condi t ions such as collateral and concen t ra ted load limits, type or me thod of a t t achmen t to the structural componenLs, or location of a t t a c h m e n t to the s tructural c o m p o n e n t s may need to be observed when hang ing system piping in pre -engineered metal bui ldings or bui ldings us ing o ther specialty structural componen t s such i~s composi te wood joists or combina t ion wood and tubular metal joists . S U B S T A N T I A T I O N : As is, 6-2.1.3 conflicts with 6-1.1, i tem b, which states tha t the points of a t t achmen t mus t be capable of suppor t ing the system (6-2.1.3 states that the a t t a ch m en t points mus t suppor t tire weight of the water filled pipe plus 250 pounds) . Further , the s tandard main ta ins that tile points of a t t achmen t mus t be substantial, bnt does no t have langnage to reinforce that dfis may need to be specifically addressed by the person responsible for the layout. Usually, the bui lding specification process is far ahead of tile process of de t e rmin ing the details of the layout, which is at the discretion of the person responsible for tile layout. Large d iameter p iping installations often are employed to accommoda te weak water supplies, and are c o m m o n i , applicat ions of l a rge~rop or ESFR sprinklers, and will be incre;Lsingly so in applicat ions us ing sprinklers with K factors of 25.

An example follows that demons t ra te s hange r and loading limit[tin[is for a c o m m o n pre-engineered building:

6-2.3.4.1 Armorers of any length connected to sprig-ups, to sprinkler dro )s, or to sprig-ups and sprinkler drops where the total cumulative length of piping measu red f rom the ~ranch ine fitting to the sprinkler(s) is 12 ft or longer shall be provided with an additional hanger. SUBSTANTIATION: The Standard includes requirements for support ing armorers exceeding 24 in. in length. The Standard does riot address shorter armorers which supply excessively long sprig-ups or sprinkler drops. The Standard does, however, include requirements f i)r tile protection of piping against d:unage where sut~iect to earthquakes including the installation of sway bracing f'Or main and branch line piping. Further, requiremems exist to [,rhyMe restraint against lateral movement for sprinkler sprig-ups 4 ft or longer. Currently, no provision exists to prevent movement of branch line couplings or t)rzmch line fittings connected to a rmore r / sp r ig -up /d rop assemblies having weights sufficient to induce rotation in the branch line fitting or coupling. This recommendat ion provides for resistance to movement in b r a n c h lines caused by the weight of piping attached to armorers where the cumulative lengdl of piping is excessive.

EXPLANATION OF NEGATIVE: PEAR(;E: This comment should have been accepted. Problems

with armorers and sprinkler drops were the [wimary failure experienced by our clients in the Northridge earthquake. The additional restraint provided by the hanger will also hel l, prevent tim shearing of sprinkler heads (which w:es the second most c o m m o n failure in Northridge earthquake), While heads may not seem ;Ls important ~s maintaining the integrity of the piping, it h:ts some hidden dangers. Even if one head ,,pens the sprinkler system will be shut down. With the turmoil ~ffter the earthquake, you don't know if a system will be un'ned on ;Ls fast as you would like.

People a r e c o n c e r n e d about their h o l n e a n d I ; t n l i l y a n d m a y leave this site with the valve impaired. There is also tile p,)ssibility of the shortage of sprinkler heads and sprinkler contractors to make tile repairs.

The Mexico City e a r t h q u a k e showed ntore fires in tile da)~ following the earthqnake rather than dnring die <lay of die earthquake. This is most likely due to gas and electric services being restored. Either the flleI source a n d / o r file ignition source wzLs restored resulting in a fire. With the sprinkler system turned off, the sprinkler system is no more valuable dlan a s'~tem down with m:}ior main faihn-es.

1. Bearing surface should, where possible, be placed against undisturbed soil• Where it is not possible, tile fill between tile bearing surface and undistrubed soil must be compacted to at le;Lst 90 percent Standard Proctor density•

2. Block height (11) should be equal to or less than one-half the total depth to the bottom of the block, (H t), but not less than tim pipe diameter (D).

3. Bluck height (it) should be chosen such that tile calculated block width (b) wtries between one and two times the height.

Tim required block area is

At, = (b)(b) = T (S0 /S , ,

Then, for a horizontal bend,

h = 2(Sf)(P)(A)sin((4/e)(h ) (Sb)

where Sf is a safety factor (usually 1.5 for thrust block design). A similar approach may be used to design bearing blocks to resist tile tllrust forces at tees, dead ends, etc. Typical w,,dues for conservative horizontal bearing strengfl~s of w, trious soil types are listed in TaMe A-6-3.2.9.

In lieu of tile ~dues for soil I,earing strength shown in Table A-6- 3.2.9, a designer miglit choose to use calculated Rankine pztssive twessure ( P ) or other determination of soil bearing strengtll

*Although die above bearing strength values have been used succe~fully in the design of thrust blocks and are considered to be conservative, flleir accuracy is totally d e p e n d e n t on accurate soil identification and evaluation. The ultimate responsibility for sblecting the proper bearing strength o f a particular soil type must rest with the design engineer.

(;~wity thrust blocks may be used to resist thrus t at vertical down bends. In a gravity thrust block, the weight of the block is the force providing equilibrium with the thrust force. The design

~ roblem is then to calculate the requirec[ volume of the thrust lock of a known density. The vertical componen t of the thrust

force in Figure A-6.3.2.9(b) is bal,'mced by the weight of the block.

A-6-3.1 (24-A-8-6.1) It is a funcktmental design principle of fluid mechanics that dynamic and static pressures, acting at changes in size or direction of a pipe, produce nnbalancd thrust forces at bends, tees, wyes, deadends, reducers, offsets, etc. T b i s p r o c e d u r e includes consideration of lateral soil pressnre and pipe/soi l friction, variables flint can be reliably de te rmined using present-day soils engineer ing knolwedge. Refer to (13-4.1) for a list of references for use in c,'dculating ,and determining joint restraint systems.

Except for the case of welded jo ints ,and approved special restrained joints, such :as provided by approved mechanical jo in t retainer glands or locked mechanical ,and push-on joints, tbe usual

joints for underg round pipe are expected to be beld in place by the soil in which the pipe is buried. Gasketed pusla-on and mechanical joints without special locking devices have limited ability to resist separation due to movement of the pipe.

A-6-3.2 (24-A-8-6.2, 24-A-8-6.2.1) Concrete thrust blocks are one of the most common methods of restraint now in use, provided stable soil conditions prew, til and space requirements permit placement. Successf i f l t l ( cking is d e p e n d e n t upon factors snch as location, availability and placement of concrete, and possibility of distrubance by fimlre excavations.

Resistance is provided by transferring the thrust force to the soil through the larger bearing area of the block such that the resultant pressure against file soil does not exceed the horizontal bearing

strength of the soil. Design of thrust blocks consists of de termining the appropriate bearing area of the block for a particular set of conditions. The parameters involved in the desigu include pipe size, design pressure, angle of the b e n d (or confignration of the f i tdng involved), :rod the horizont:d I)earing strengda of the soil.

Duggan, Fire Sprinkler Design COMMENT ON PROPOSAL NO: i3-i77 ' - RECOMMENDATION: Accept proposal 13-177 (Log #42) which would insert the words "when required by 4-14.4.3.5.4" to 4- 14.4.3.5.1." SUBSTANTIATION: The Committee Statement justifying the rejection of this proposal is inaccurate. 4-14.4.3.5.4 does indicate all of the conditions under which seismic bracing is needed to protect against verdcal motion. 4-14.4,3.5.4 indicates the conditions under which "braces shall be arrange d to resist the net vertical reaction produced by the horizontal load." The wording of this proposal should be accepted for the following reasons:

1. The upward verdcal reacdon to the horizontal load is the only upward motion considered by NFPA 13.

2. No other Upward vertical motion is considered by any other building code o r standard.

3. No proposal has been submitted to NFPA for consideration of any other source of upward vertical modon.

4. Acceptance of this wording Would define the minimum requirement for compliance with this aspect of 4-14.4.3.5.1 of NFPA 13 and would be consistent with the g0al of providing a standardized design approach for users of NTPA 13.

5. Acceptance of th~s wording would not preclude any authority having jurisdiction from requiring something else.

13- 150- (Table 6-4.5.3): Accept SUBMrrTER: Daniel (3-. Duggan, Fire Sprinkler Design COMMENT ON PROPOSAL NO: t3-178

I RECOMMENDATION: Delete the'Assigned Load Table: Table 6- 4.5.3 (4-14.4.3.5.3). SUBSTANTIATION: The Assigned Load Table should be eliminated-for the following reasons:

1. It is always incorrect. 2. The justification for lowering the loads and maintaining the

Assigned Load Table in I tem 2 o f the Committee Statement is inaccurate. Branch lines 2 1/2 in. and larger are not required by NFPA 13 to be braced.

3. T h e existence of the Assigned Load Table influences users of NFPA 13 toincorrecdy conclude that the listed sway brace components are capable of supporting the loads in the Assigned Load Table.

4. Arbitrarily reducing the assigned loads would inadvertently invite under designed braces. COMMITTEE ACTION: Accept.

Acceptance of this comment requires the following edRorial revisions so that reference to Table 6-4.5.3 of the Preprint is removed:

1. Delete Exception No. 1 to 6-4.5.3 in its entirety. 2. Renumber Exception No. 2 as Exception No. 1 to 6-4.5.3 and

revise as follows: "Where the use of other horizontal force factors is required or

permitted by the authority having jurisdiction, they shall take precedence."

3. Delete Exceptions No. 3 and No. 4 to 6-4.5.3 in their entirety. 4. Delete Figures A-6.4.5(a) and A-6-4.5(b) in the Preprint.

COMMITTEE STATEMENT: These exceptions and figures were deleted as they refer to Table 6-4.5.3 which is proposed for deletion. Exception No. 3 was deleted as it is addressed by Section 6-4.5.10 of the Preprint. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 20 VOTE ON COMMITTEE ACTION:

AFFIRMATIVE: 18 NEGATIVE: 1 NOT RETURNED: 1 Patel

EXPLANATION OF NEGATIVE: MARTIN: The action of the Committee to eliminate~the assigned

load Table 6-4.5.3 is regrettable. I agree with the submttter that the assigned loads as reflected in

ihe table a re high, but to eliminate the table in its entirety removes an option the designer and authority having jurisdlction previously had. The effect of this action requires thedes igner to determine horizontal loads without giving the user of the standard sufficient guidance on how to do so.

Perhaps moving the table to the appendix would be less dramatic allowing for complete elimination in a future revision cycle. COMMENT ON AFFIRMATIVE:

FLEMING: In new Exception No. 1 to 6-4.5.3, the words "required or permitted" may produce enforceability problems. Perhaps "specified" would be better.

"...For tension only braces, *och as prestretched color coded aircraft cable...." SUBSTANTIATION: Deletion of this wording was not in response to a proposal that was submitted. "It wasproposed by a Committee member during the development of Committee Proposal 13-37 (Log #CP7). An attempt was made to remove this wording by errata to the 1996 edition under the guise that it was redundant. The wording was not removed by errata because it is not repeated elsewhere in the standard and therefore not redundant; and furthermore, the wording was the result of a properly submitted proposal, subjected to public review and comment, and voted on at the Annual Meeting'by the full NFPA membership. The only risk in retaining this wording is that the users of NFPA 13 would know exactly what is meant by "tension only bracing." Deletion of this phrase is a solution to a problem that does not exist. COMMITTEE ACTION: Reject.

13- 153 - (6-4.5.5 and 6-4.5.7): Accept SUBMITTER: Technical Committee on Hanging and Bracing of Water Based Fire Protection Systems COMMENT ON PROPOSAL NO: 13-37 RECOMMENDATION: 1. Revise the second to the last sentence in Section 6-4.5.5 in the Preprint to read as follows:

"The loads determined in 6-4.5.3 shall not exceed the lesser of the maximum allowable loads provided in Table 6-4.5.5 of the ummffacturer's certified maximum allowable loads for 30-44, 45-59, 60 .-908_.~q, and 90degree brace angles."

13- 154- ([64.5.10] 4-14.4.3.5.10): Accept in Principle SUBMITTER: Daniel C. Duggan, Fire Sprinkler Design COMMENT O N PROPOSALNO: 13-183, 13-189 RECOMMENDATION: Retain the original wording of this paragraph:

"... shall be provided on all feed mains, all cross mains, and branch lines with a diameter of 2 1/2 in. and larger." SUBSTANTIATION: The wording of this paragraph, prior to the 1996 change cycle, read "all feed and cross mains." In the 1996 change cycle the wording requiring lateral bracing of 2 1/2 in. and larger branch lines was moved from the "Exception" under "Sway bracing is n~)t required for branch lines" to the paragraph regarding lateral bracing of feed and cross mains, This was done, ostensibly, because 2 1/2 in. and larger branch lines should be laterally braced in the same manner as mains. Thus, the exception under the branch line paragraph was deleted and the wording about 2 1/2 in. branch lines was added to 4-14.4.3.5.10. This action actually weakened the requirement for lateral bracing of 2 1/2 in. branch lines by maki'ng it subject to the exceptions under the feed and cross main paragraph.

For many years feed and cross mains have been required by NFPA 13 to be laterally braced regardless of pipe size. Neither of the above referenced proposals propose that this be changed. Rather, these proposals suggest wording changes intended to clarify whether 2 iu. and smaller hose connection piping or standpipe piping should be treated as main piping or branch line piping.

PresenOy, the lateral sway bracing requirements of 4-14.4.3.510 apply to:-

1. All feed mains (regardless of pipe size) 2. All cross mains (regardless of pipe size) 3. All branch lines (2 1/2 in. and larger pipe size) Since changing the requirements to apply to only 2 1/2 in. and

larger feed and cross mains was not the subject of the substantiation for either of these proposals, the model codes do not include exceptions from sway bracing based on small pipe sizes and the fact that this action would dramatically weaken the requirements of NFPA 13, the present wording of 4-14.4.3.5.10 should not be changed. COMMITTEE ACTION: Accept in Principle.

1. Revise the wording proposed by the snbmitter to Section 6- 4.5.10 of the Preprint so that it reads as follows:

"...shall be provided on all feed and cross mains regardless of size and all branch lines and other ninin~ with a diameter of 2 1/2 inches and larger." . . v . •

• renumber the remaining sections accordingly. COMMN'TEE S T A ~ : Thence changes make this sectio n consistent with other requirements in NFPA 13 for seismic bracing.

Duggan, Fire Sprinkler Design COMMENT ON PROPOSAL NO: 13-188 RECOMMENDATION: Delete all references in 4-14.4.3.5.13 a n d A-4-14~4.3.5.13, including detail~, of #12 440 lb wire restraints. SUBSTANTIATION: All references to #12 440 Ib wire restraints should be purged from NFPA 13 for the following reasons:

1. The strength of the connection details is unknown for the #12 440 lh wire.

2. All four of the manufacturers of listed sway brace assemblies and devices manufacture cost effective, readily available, listed sway brace assemblies.and devices fo r2 in. and smaller piping, making the acceptance of unlisted assemblies and devices unnecessary..

3. Inclusion of#12 440 Ib wire as an acceptable "restraint" causes a confusing distinction to be drawn (only in NFPA 13) between the terms "restraint" and "brace," which is not defined anywhere in NFPA 13. Without #12 440 lb wire, there would be no need to draw such a distinction. COMMITI'F.~ ACTION: Accept in Principle in Part.

COMMENT ON PROPOSAL NO: 13-37 RECOMMENDATION: Insert a new section following 6-4.5.13.3 as it appears in the 1999 Edition Preprint included as part of the t999 Spring Association Technical Meeting Report on Proposals to read as follows:

6-4.5.13.4 Drops 8 ft or longer which directly supply sprinklers in a pendent position below the ceiling shall be restrained against lateral movement. SUBSTANTIATION: The Standard includes requirements for the protection of piping against damage where subject to earthquakes including the installation Of flexible pipe couplings for "mare" pip!ng, the provision of seismic separation assemblies where pipmg crosses building seismic separation joints, provision of " clearance where piping passes through holes in structural features, and installation of sway bracing. Further, requirements exist to provide restraint against upward or lateral movement for branch lines and sprinHer sprig-ups 4 ft or longer. Currently, no • provision exists to prevent movement of longer sprinkler drops, which are known to move in response to seismic events. This recommendation provides for restraint against lateral movement of sprinkler drops 8 ft or longer which supply sprinklers in a pendent position below a ceiling. Such restraint should be required to avoid damage to the ceiling/structure due to seismically-induced movement~ More importantly, such restraint should be required to prevent damage to system components such as the sprinkler or the branch line fitting, to limit the potential for system failure during a seismic event.

Waish, CT State Fire Marshal's Office COMMENT ON PROPOSAL NO: 13-191 RECOMMENDATION: Relocate requirement for retaining straps on Gtype clamps used toat tach hangers to 'new Section 6-4.1.1. SUBSTANTIATION: While we agree with the submitter, this section should be relocated. As currentl~ located, it appears that the requirement for retaining-straps on t3-type clamps applies only where sway bracing is required. For example, if branch lines do not require sway bracing, it may appear that retaining straps for the C-type clamps on thesebranch lines are not required.

Since the requirement for retaining straps on all C-type clamps is intended to he applicable whenever protection for pipmg against damage from earthquake is required, it should be located up with the general requirements. COMMrI ' rF~ ~xC'rlON: Accept in Principle.

COMMENT ON PROPOSAL NO: 13-209a RECOMMENDATION: Delete this chap te r and establish a new docuq~ent to cover "Design of Sprinkler Systems." SUBSTANTIATION: Installation and design are two-distinct areas and deserve separate documents . Also, the a m o u n t o f material now conta ined in the "partially revised" NFPA 13 is so large that it will become c u m b e r s o m e to use.

It is no t practical for the public to call ou t each specific reference to design-related material in the proposed new edi t ion of NFPA 13.

are designed to respond quickly to growing fires and deliver heavy discharge to suppress fires rather than to control them. ESFR sprinklers should not t,e relied on to provide suppression if they are used oulside the design parameters.

While these sprinklers are intended primarily for use in high-pile storage situations, this section permits their use and extension into adjacent portions of an occupancy that might have a lesser classification.

A-7-6.5.1,1 (231-A-9-1.3) Storage in single-sto[y or multistory buildings can be permitted, provided the maximum cei l ing/ roof height as specified in Table 9-1.1 is satisfied for each storage area.

A-7-6.5.2 (231-A-9-2, 231C-A-10-3) Design parameters were determined from a series of full-scale fire tests that were conducted as a joint effort between Factor), Mutual Research Corporation and the National Fire Protection Research Foundation. (Copies of the test reports are available fi'om the NFPRF.)

Also refer to Comment 13-160 (Log #127) for additional revisiolls to the ESFR discharge criteria. COMMITTEE STATEMENT: This meets the intent of the submitter by consolidating the dischalge criteria for large drop and ESFR sprinklers. This action also updates the discharge criteria as found in the 1998 editions of NFPA 231 and NFPA 231C. Also see Preprint of Chapter 7 at the end of this report. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 24 VOTE ON COMMITTEE ACTION:


KEEPING: In the Committee Action, a new Table 7-6.5.1.2 is being created by revising Table 9-1.1 from the 1998 edition of NFPA ~31. This is the correct reference; however, on the artwork that illustrates this new table, it has mistakenly been marked as Table 7-6.5.6.1. Care must be taken to insure that this typographical error does not end tip on the final draft of the standard.

SCHUMANN: Retain names for Tables 7-6.4.1.1, 7-6.4.1.2, 7- 6.5.6.1, and 7-6.5.1.2. Also, include a configuration column for Table 7-6.4.1.2 if the title of the table does not indicate that it is for rack storage configurations.

sprinklers on each of 4: b ranch lines. The design shall include a m i n i mu m opera t ing area of 1600 f(2.

SUBSTANTIATION: 1. Approved ESFR sprinklers having a nominal K-factor of 25.2 have been available for almost a year. There has been considerable interest in these sprinklers and their use should be detailed in this standard.

2. By incorporating ,nfi~rlnation on ESFR sprinklers having 26 K- factors now, the need to issue a TL& will be avoided. This is an important change whi,:h should be incorporated in-cycle.

3. An extensive series of fire tests has been conducted at Underwriters Laboratc,rics using the Grinnell Model ESFR-25 sprinkler to estahlish the minimum design pressures for the commodities for whicl, this sprinkler will be Listed. A copy of their report is attachec,. It is noted that in a comparative test of ESFR sprinklers having a nominal K-factor of 14.0 arid those having

a nominal K-factor of 25.2. the higher K-factor sprinklers demonstrated superior petforinance. It is also noted that the pressures which are proposed are intended to provide the same or slightly higher densities for ESFR's having K-factors of 25 as colnpared to ESFR's having K-factors of 14.

4. The wording of Section 7-6.5.2 (13-5.3.5.2) has been changed to delete reference to the appendix Table A-7.6.5 since information in that table has already been included in the non- appendix tables dealing with ESFR sprinklers. COMMITTEE ACTION: Accept in Principle.

Do not accept the revisions to Sections 7-6.5.1.1 and %6.5.2 as proposed by fl~e submitter. Revise file submitter's tables as follows:

Notes." 1. For $I units, 1 ft = 0,:~048 m; 1 sq ft = 0.0929 sq m: 1 psi = 6.895 kPa: 1 gpm = 3.785 L/In in 2. Wet systems only. 3. Sprinkler operating pressures and number of sprinklers in tile design are based on tests in which the clearance was

ft to 7 ft between the sprinkler deflector and the maximum height of storage. 4. The shape of the design area shall be in accordance with Section 7-6.5.4. 5. Where u~ed in this application. ESFR protection is expected to control rather than to suppress the fire. 6. The design area shall consist of the most hydraulically demanding area of 20 sprinklers, consisting of 5 sprinklers

Refer to Comment 13-55 (Log #127a) for installation requirements concerning the K-25 ESFR sprinkler in Chapter 5. COMMITTEE STATEMENT: The revisions made by the Technical Committee reflect the current approval and installation of these types of sprinklers. The Technical Committee notes that while these sprinklers are not permit ted to be installed as ESFR sprinklers at the lower pressures specified by the submitter, they are permitted at these lower pressures pet" Section 4-4.9 of the 1996 edition of NFPA 13 for Special Sprinklers. Due to the emergence of this relatively new technology, the Technical Committee has agreed to further study this matter. Tables 7-6.5.6.1 and 7-6.5.8 were further revised to correct information concerning the K-11 ESFR sprinkler. See Preprint of Chapter 7 at the end of this report. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 24 VOTE ON COMMITTEE ACTION:

AFFIRMATIVE: 22 ABSTENTION: 1

COMMENT O N AFFIRMATIVE: HOOVER: I am voting affirmatively but with a comment on the

two new entries in Table 7-5.2.1.1(c): Under "up to 25" in a "30" foot building there is an entry for 12

sprinklers (K=24.2-26.2) at 20 psi; and under "up to 25" in a "35" foot building there is an enttw for 12 sprinklers (K=24.2-26.2) at 30 psi.

As far as I can tell by reading the UL test report, this sprinkler has never heen tested in this configuration with ruhber tires as the commodity either on-side or on-tread. As I remember, this comment was still being discussed as Todd and I had to leave to catch a plane to Chicago. With our desire to have proof before we place anything in the standard, I'm surprised that this comment was accepted.

The Tire Committee made this mistake previously. Tile), accepted ELO hardware based on tests run with commodities other than tires. However, when the chance came to test the ELO versus tires, the committee found that the ceiling steel temperatures could not be controlled. A fluke? Maybe! But, to be on the safeside, the Tire Committee relegated the ELO to being no better than 17/32" sprinklers in order to keep it in the Rubber Tire Standard. Could a similar problem occur with this ESFR sprinkler? One assumes not, but until tires are the test commodity, we really don' t know.

This occurrence may point out a potential problem with NFPA 13 taking over the sprinkler portions of other standards. The Tire Committee would not have accepted this c o m m e n t and would have asked the manufacturer to run tests with tires. Or, at least there would have been a great deal of discussion before they were convinced. The Sprinkler Committee, on the other hand, did accept it without ure tests. Will we, the Sprinkler Committee, accept hardware, or a remote area design, or a presstrre requirement in the future without appropriate testing where the Tire, Roll Paper, Hanger, or other committee would ask for- further testing because they have more experience with their unique commodity or occupancy? I fear we will.

As I said, I was not able to stay for- the whole discussion and maybe the Sprinkler Committee did discuss this issue thoroughly and completely. I do not intend to impugn the committee's integrity, but I still d o t h i n k there is a concern to be raised.

KEEPING: The new standard is supposed to refer to sprinklers bv their nominal K-factors. Therefore, rather than referring to the ESFR sprinklers with K's of "I 1.0-11.5," "13.5-14.5," and 24.2-26.2," these devices shonld be consistently referred to as "11.2," "14.0," and "25.2.

EXPLANATION OF ABSTENTION: BELL: Sprinklers having a nominal K-factor o f 25 have

successfully completed a series of large-scale fire tests at pressures less than those proposed for Chapter 7. It may be premature to only specify these higher pressures as part of this Standard.

SUBSTANTIATION: This information is not a design approach, but an installation requirement. Tile commit tee rejected the initial proposal stating these paragraphs pertain to tile subject of hazard analysis. The requirement to install quick response sprinklers in a light hazard occupancy is not per t inent to the analysis o f the hazard. As defined in 13-5-2.1.2, the hazard analysis reviews the filel load, storage arrangement , etc. After complet ing the analysis, then the need to install QR sprinklers is determined. This is an INSTALLATION issue, the same as allowing intermediate and high temperature sprinklers in ordinany and extra hazard occupancies. We need to be consistent in applying logic when placing criteria. Leaving these paragraphs in the current location simply because we placed them there in 1996 is inappropriate .

Test data is no t available for encapsulated products stored h igher dmn 15 ft (4.6 m). However, in rack storage tests involving encapsulated s torage 20 ft (6 m) high, increased protection was needed over thin for nonencapsu la t ed storage.

The protect ion specified in Chapte r 6 contempla tes a m a x i m u m of 10-ft (3-m) clearances from top of storage to sprinkler deflectors for

(13.5-mm) orifice sprinklers and 80- It-' or 100-ft-' (7.4-ft-' or 9.3-m-~) - sprinkler spacing. These and o the r tests have indicated that, with densities o f 0.40 g p m / f t 2 [0.27 (L/s) /m' - ' ] and higher, better results are obta ined with 17/.~,~-in. (13.5-ram) orifice

A discharge pressure o f 100 psi (689 kPa) was used as a ' s tar t ing poin t on one of the fire tests. It was successful, bu t has a 1 ~/,-ft (0.5-m) clearance between the top of storage and ceiling sprinklers. A clearance of 10 ft (3.0 m) could have produced a different result due to the tendency of the h igher pressure to atomize the water and the greater distance that the fine water droplets had to travel to the bu rn ing tirol.

"I he worst applical)le height-clearance relationship that can be expecled to occtn" should lye fonnd, and protection shonld be designed for it.

A-7-3.3.2.2 (231-A-7-2.2) Test data is noi available for all combinations of commodities, storage heights, and clearances. Some

! of die protection criteria in this siandard are based on extiapolations of iesl dala for other commodities and storage configurations, as well ,|s available loss data.

F~l exanlple, their is yen,' limited test data for storage of expanded plastks higher lhan 20 ft (6 m). The protection criteria in this standard fol expanded plastics higher than 20 ft (6 in) are extlapolated fi-ony tesi data for expanded plastics storage 20 ft (6 m) and less in height and test data for nnexpanded plastics above 20 ft (6 I n ) ,

Further exantples can be found in the protection criteria for clearances | |p to 15 fi (4.6 m). Test data is lin|ited for clearances greater than 10 ft (3.0 m). It should be asst |med that, if protection is adequate tbr a given storage height it| a bt|ilding of a given height, the same protection will protect storage of any lesser height in the same building. For exantple, protection adequate for 20-ft (6.l-m) storage in a 30-ft (10-n|) building [10-ft (3.0-m) clearance] would also protect 15-fl (4.6-n|) storage in a 30-ft (10-m) building [15-ft (4.6-m) clearance]. Therefore, the protection criteria in Table 7-2.2 for 15-ft (4.6-m) clearance are based on the protection c|-iteria for sto|age 5 fl ( 1.5 m) higher than the indicated height with 10-ft (3.0-m) clearance.

Table 7-2.2 is based on tests that were conducted p|'imarily with high- ten|pelat |ne-rated, 17/3_,-in. (13.5-nlm) orifice sprinklels. Other tests have demonstrated that whe |e sprinklers are used with orifices greater than ~r/:~_, in. (13.5 ram), ordinary temperature sprinklers are acceptable.

7-4.2.2.2.1 (231C-6-11A.) For Class I, II, III, or IV commodities encapsulated or nonencapsulated in single- or double-row racks, ceiling sprinkler water demand in terms of density (gpm/ft ~) [ (L /min ) /m -~ ] and area of sprinkler operation [it ~ (m ~) of ceiling or roof] shall be selected from the curves in Figures 7-4.2.2.1.1(a) through (g) as directed by Table 7-4.2.1.5. The curves in Figures 7- 4.2.2.1.1(a) through (g) also shall apply to portable racks arranged in the same manner as single- or double-row racks or multiple-row racks. The design shall be sufficient to satisfy a single point on the appropriate curve related to the storage configuration and commodity class. It shall not be required to meet all points on the selecte d curve. Figure 7-4.2.2.1.3 shall be used to adjust the density for storage height unless otherwise specified. For SI units: 1 ft = 0.3048 m.

74.2.2.2.2-1- (231C-6-11.-1-]~) Design curves for single- and double- row racks shall be selected to correspond to aisle width. For aisle widths between 4 ft (1.22 m) and 8 ft (2.44 m), a direct linear interpolation between curves shall be made. The density given for 8- ft (2.44-m) wide aisles shall be applied to aisles wider than 8 ft (2.44 m). The density given for 4-ft (1.22-m) wide aisles shall be applied to aisles narrower than 4 ft (1.22 m) down to 31/,., ft (1.07 m). Where aisles are narrower than 3 I/.o ft (1.07 m), racks shall be considered to be multiple-row racks.

A-2-2 (231-A-2.1, 231C-A-2.1l Specification o f the type, amoun t , and a r r a n g e m e n t of combust ib les for any commodi ty classification is essentially an a t tempt to def ine the potential fire severity, based on its bu rn ing characteristics, so that the fire can be successfully control led by the prescribed sprinkler pro tec t ion for the commodi ty class. In actual storage situations, however, many storage arrays do not fit precisely into one of the f imdamenta l classifications, therefore, the user needs to make j u d g m e n t s after compa r ing each classification to the existing s torage condi t ions . Storage arrays consist of thousands o f products , which make it impossible to specify all the acceptable variations for any class. As an alternative, the Techmcal Commit tee on Genera Storage has classified a variety o f c o m m o n products in this append ix based on j u d g m e n t , loss exper ience, and fire test results.

A-242.1.1 (231-A-2-1.1.1, 2:~1C-A-2-1.1,1) Commodity classification is governed by the types and amounts of materials (e.g., metal, paper, wood, plastics) that are part of a product and its primary packaging. However, in a storage or warehouse situation, classification is also affected by such factors as the primary storage or shipping container material, the amount of air space, and the location c,f the more hazardous materials within the container. For example, a Group.A plastic product enclosed in a five-sided o1" six-sided metal container can be considered Class II; while a ceramic product heavily wrapped in tissue paper and ~laced in a corrugated carton can be considered Class II1.

SUBSTANTIATION: The inclusion of Exception No. 1 corrects this material to agree with the 1998 edition of NFPA 231C.

Inclusion of ESFR sprinklers in the exception as noted and the revision to allow the use o f slatted shelves above 12 ft in height where ESFR sprinklers are used in item (d) is based upon UL Report R18711 97NK 41803 dated May 4, 1998.

These tests involved nominal 19 ft high storage of Group A plastics in cartons on double-row racks protected by ESER sprinklers operating at 50 psi. Test 1 provided nominal 6 in. u'ansverse flues at rack uprights while test 2 provided 3 in. transverse flues at rack uprights. Two sprinklers operated in test 1 with damage confined to one rack bay up 7 ft above ttle floor. Ill test 2 with 3 in. transverse flues, two ESFR sprinklers operated. Damage was again confined to one rack bay up 7 ft above the floor with minor damage above 7 ft and into tile first boxes in adjacent rack bays in the south segment of the double row rack.

Note: Support ing material available for review at NFPA Headquarters . COMMITTEE ACTION: Accept.

See Preprint of Chapter 7 at the end of this report. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 24 VOTE O N COMMITTEE ACTION:


EXPLANATION OF NEGATIVE: FLEMING: I am hereby changing my vote on Comments 13-174

(Log #CC203) and 13-181 (Log #12) to negative, in agreement with the hallot statements of bit'. Hankins.

The discussion of slatted and solid sheh'es in Comment 13-174 additionally caused us to take a look at how the standard will address solid shelves, and we ale. concerned that there is a significant conflict within tile document that needs resolution by the Technical Correlating Committee.

Tile definition of "solid shelving" in Section 14.9 states that it is any shelving that obstructs water penetration through tile racks. Figure A-1-4.9(c) shows double-row racks with shelves. The figure includes some transverse and longitudinal fines. Yet, Section 7- ,t. 1.5.2 states that sprinklers are needed at evely level of rack storage where tile shelves obstruct both the longitudinal and transverse flues. This is being misinterpreted by some to indicate that solid shelving essentially does not exist unless both longitudinal and transverse fines are blocked, and that blocking one set of flues is not a problem.

The Committee has failed to address the situation in which the transverse or longitudinal titles are blocked.

The Committee should consider one of two possible solutions: 1. State the intent of the Committee in an Appendix Note to 7-

4.1.5.2: "For protection of single-, double-, or multiple-row racks with

solid shelves that do not obstruct both the longitudinal and transverse flue spaces, the protection outlined in this standard for racks without solid shelves should be utilized, but with the addition of one or more levels of in-rack sprinklers. In-rack sprinklers are not required at every level unless both longitudinal and transverse flues are blocked."

2. Provide some specific criteria in new Sections 7-4.1.5.3 and 7- 4.1.5.4 for tile condition in which one set of fines is blocked:

"7-4.1.5.3 For protection of storage where the transverse flue spaces are obstructed and the longitudinal flue spaces are not obstructed, in-rack sprinklers shall be installed in the longitudinal fines at evmw other tier of storage."

"7-4.1.4.3 For protection of rack storage where tile transverse flue spaces are not obstructed and the longitudinal flue spaces are obstructed, in-rack sprinklers shall be installed in the transverse flue spaces at eveo, other tier of storage."

HANKINS: As currently written, 7-4.1.1(c) would pernfit KI4 ESFRs ~o protect cartoned expanded and exposed unexpanded plastic in slatted-shelf racks. The testing used to substantiate this application involved cartoned nnexpanded plastic. The application should be limited to only the tested commodity. COMMENT ON AFFIRMATIVE:

KEEPING: Tile new standard is supposed to refer to sprinklers hy their nominal K-factors, however, the Committee Action still makes reference to "5/8-in. orifice sprinklers." This reference should be changed to "K-I 1.2 sprinklers." Further, reference is also made to "K-14," whereas the proper form should be "K-14.0."

SUBSTANTIATION: Normal rack construction consists of a single upright with horizontal load beams directly attached to either side. Paragraph 7-4.3.1.,'2 compels the sprinkler to be located at an intersection which does not exist unless there are four uprights at the intersection. In addition, the pipe hanger must be attached to the single upright where the fitting would be located if the sprinkler was located per 7-4.3.1.2. If the longitudinal flue is 6 in. wide, the 3 in. rule cannot be accomplished. Needs guidance or clarity. COMMITTEE ACTION: Accept in Principle. Revise Section 7-4.3.1.2 of the Preprint to read as follows:

"7-4.3.1.2 (231C 7-5) In single-row, double-row, or multiple-row racks, a minimum 6 inch (152.4mm) vertical cleat" space shall be

Face sprinklers in such racks shall be located a minimum of 3 inches (76.2 ram) from rack uprights and no more than 18 inches (460 ram) from the aisle face of storage. Longitudinal flue in-rack sprinklers shall be located at the intersection with the transverse flue space and with the deflector located at or below the bottom of horizQntal load beams or above or below other adjacent horizontal rack members. Such in-rack sprinklers shall be a minimum of 3 inches radially: from the side of the rack uprights."

T he references to 99 should also be general , no t paragraph specific, e.g., "sprinkler systems in hyperbaric chambers shall conform to the r equ i rements o f NFPA 99, Chapter 19." SUBSTANTIATION: Extracting only bits and pieces of NFPA sprinkler requi rements is confus ing and will lead to errors and conflicts when NFPA 99 requ i rements change . COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: T he Technical Commi t t ee believes that specific spr inkler system discharge criteria informat ion from NFPA 99 conce rn ing hyperbaric chambe r s should be easily identified by the users of NFPA 13 and therefore this informat ion should be copied into NFPA 13 us ing NFPA's extract policy.

A-7-5.2.1.1 (231D-A-,LI.2) The protect ion criteria in Tables 7- 5.2.1.1(a), (b), and (,:) have been developed from fire test data. Protection requi rements for other- s torage me t hods are beyond the scope of this s tandard at t h e p r e s e n t time. From recent fire testing witl'l densities o f 0.45 g p m / f t -~ [18.3L/ra in) /m'- ' ] and higher, t h e r ( have been indications that large orifice sprinklers at greater than 50-ft'-' (4.6-rn'-') spacing produce better results than the I/,2-in. (12.7- ram) orifice sprinklers at 50-ft ~ (4.6-m'-') spacing.

Tables 7-5.2.1.1(a) and (b) are based on opera t ion o f s tandard sprinklers. Use of "qaick response" or o the r special sprinklers should be based on appropr ia te tests as approved by the authori ty having jurisdict ion.

The cur ren t changes to Tables 7-5.2.1.1(a), (b), and (c) represent test results from rubber tire fire tests pe r fo rmed at the Factory Mutual Researcit Center .

Storage heights and configurat ions, or both, [e.g., au tomated material hand l ing systems above 30 ft (9.1 m) ] beyond those indicated in the table have not had sufficient test data developed to establish r e c o m m e n d e d criteria. Detailed eng inee r ing reviews of the protect ion should be conduc ted and approved by the authori ty having jur isdict ion.

13-174 (Log #CC203) HANKINS: Table 7-5.2.1(c.) permits storage of tires on side and

on tread up to 25 ft in a 35-ft bui lding to be protected by ESFR sprinklers. The test used to suppor t this opt ion was done with on- side storage, which is significantly less cha l lenging to ESFR sprinklers than on-tread storage. It is my clear recollection that it was agreed by the Commi t tee that ESFR sprinkler protect ion in buildings h igher than 30 ft would be limited to on-side storage only. The talkie does not reflect this agreement . COMMENT O N AFFIRMATIVE:

SCHUIVL~_NN: U n d e r the title of Figure 7-5.2.1.1, there are instruct ions on how t~ use the table. These instruct ions should be located between the table and its title.

Table 7-5.2.1.1(a) needs to be revised as follows: U n d e r i tem (4) Palletized portable rack storage;

Second column, r~move "Up to 5" and "Over 5 to 20." Third co lumn remow_ ~ "0.19" and "(See Figure 7-5.2.1.1)" Fourth co lumn remove "2000" and; Fifth co lumn remove "2000".

U n d e r item (6) Single-, double- and multi-row fixed rack storage on pallets, on-side or on-tread;

Add a line to the table in the third co l umn following the first instance of the words "0.30 plus h igh-expans ion foam."

Conce rn ing Mr. Hankin ' s negative vote, I do not wish to change my vote on this c o m m e n t but offer some explanat ion. It is true that the ESFR protect ion table included with this co m m en t , in the material sent out for ballot, does not reflect the Commit tee ' s action. The correct table, revised in accordance with the Commit tee ' s action, can be found with the material for C o m m e n t 13-160 (Log #127).

13- 186 - (7-5.4 t h rough 7-5.4.3): Reject SUBMITTER: Richard E. T h o n n i n g s , Amer ican Insurance Sere'ices Group, Inc. COMMENT ON PROPOSAL NO: 13q R E C O M M E N D A T I O N : All design-related material shonld be conta ined in a separate d o c u m e n t or revert back to NFPA 231F. NFPA 13 should limit its scope to installation. S U B S T A N T I A T I O N : Installation and design are two distinct areas and dese~v,e separate documen t s . Also, the a m o u n t of material Jmw conta ined in the "partially revised" NFPA 13 is so large that it will become c u m b e r s o m e to use. T he evolution of pcrfm mauce-based s tandards also makes it advan tageous to place design topics in a d o c u m e n t separate fl-om installation requi rements . Two individual d o c u m e n t s will make it easier" to use arr¢l ulxlate in the futnre.

It is n o t p t a c t i c a l for the public to carl ou t each specific reference to design-lelaled material in the p roposed new Chapte r 1 o f NFPA 13. NFPA has sadh' chosen an awkward change process for the 1999 e d m o n of NE['A 13 which seems des igned to h inder

substantial public input. The proposed 1999 edi t ion is obviously more than a "partial revision." COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: NFPA 13 has traditionally addressed both design and installat ion r equ i r emen t s of sprinkler systems which are both highly related. The inclusion o f sprinkler system discharge criteria for the protect ion o f roll paper from NFPA 231F into NFPA 13 consolidates and bet ter coordiantes such infornmtion.

SUBSTANTIATION: The Technical Correlating Committee is commended for its recognition of the unique requirements set forth fox- the design and performance criteria fox- sprinkler systems in Class A hyperbaric chambers per NFPA 99, Chapter 19. NFPA has just completed its review cycle for the 1999 edition which will be submitted for adoption at the November 1998 meeting. Proposal 13-85 (Log #CP80) proposes to extract material from tire 1996 edition, which is different fl-om the text proposed for the 1999 edition. Extraction of material from another text makes it difficult to insure continuity across the two documents.

SUBSTANTIATION: The incorporat ion of excerpts from NFPA 409 is incomplete and may be misleading. In reality, NFPA 409 integrates several in te rdependent fire protect ion approaches. In addition, any one of these approaches may itself have complex conditions that govern the specific method of application of that approach. The sprinkler systems that are required by NFPA 409 are good examples of complex approaches that have requiremems that van y according to occupancy, size, and o ther provided fire protection systems. The proposed excerpts provided in NFPA 13 describe only one of several conditions for the installation of sprinkler systems. The excerpts do not reflect the wide variations that NFPA 409 requires, fi-oin closed sprinkler systems to foam water deluge sprinkler systems. The system required may vary based on condition and size of housed aircraft, hangar size, or the presence of supplemental under wing fire protection systems,

If the objectives o f excerpt ing are to be pursued, the Airport Facilities Commit tee suggests a correlating task group be formed to ensure the appropriate requirements of NFPA 409 are excerpted into NFPA 13. COMMITTEE ACTION: Accept in Principle. 1. Delete Sections 7-5.18.1 through 7-5.18.3.4 in their entirety without replacement.

13- 228 - ([8-4.3.5 (New)] 6-4.3.5): Reject SUBMITTER: William N. Bi-ooks, Eichlea Engineers Inc. COMMENT O N PROPOSAL NO: 13-248 RECOMMENDATION: Reject Commi t t ee Action. Accept Proposal 13-248 (Log #159). SUBSTANTIATION: The Commit tee ' s substant ia t ion corrtains the reason for the proposal. Tha t is, paddle type water flow devices are tested with substantially lower velocities than will occur du r ing a design flow condit ion. It's interest ing how the commi t tee creates a circular substant ia t ion for an issue which hasn ' t been presented before.

1. There is no limit on system velocity, and the .Committee does not wish to establish one.

2. Vane type flow switches a te tested at approximately 18 f t / sec max, yet there are no restrictions off their installation.

3. The commi t tee does not feel it would be a p rob lem until the fire opens more sprinklers. It would seem that the Commi t t ee should be conce rned about all flows, up to and irrcluding a "supply" flow, in order to assure the integrity o f system c o m p o n e n t s .

4. System velocities can increase dramatically if available pressure is high and piping sizes are reduced in o rder to use up all o f the available pressure.

This is a benign proposal, and one which will require flow switches to be installed on appropr ia te sized piping. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The Commi t t ee believes that this is an issue for the listing agencies and that the listing agencies should de te rmine the proper applicat ion o f these devices. Identif ied field problems should be submi t ted to the listing laboratories and the Commit tee . The Commi t tee also notes that these types of switches can become damaged for reasons o the r than high water velocities. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 26 VOTE O N COMMITTEE ACTION:

13- 236- (10-2.2.1 Exception ): Accept in Principle SUBMITTER: Kenneth E. I sman, Nat'l Fire Sprinkler Assn. COMMENT ON PROPOSAL NO: 13-257 RECOMMENDATION: Revise Exception No. 3 to read:

"Modifications affecting 20 or fewer sprinklers shall not require testing in excess of normal static pressnre."

Add a new Exception No. 4 to read: "Where an addit ion ol modif icat ion is made to an existing system

affecting more than 20 Sl)linklers, the new port ion shall be isolated and tested at not less than 50 psi (3.4 bar) in excess of no lmal static pressure for 2 hours."

S U B S T A N T I A T I O N : This c o m m e n t is being made for a n u m b e r o f reasons. Tile first is to br ing N F P A 13 into a g r e e m e n t with NFPA 25. Section 2-4.3 o f NFPA 25 requires a hydrostatic test when t'epairs o r r ep lacement affected more than 20 sprinklers. NFPA 1 3 n e e d s to give gnidance on how to do this test.

A n o t h e r reason for this c o m m e n t is that the hydrostatic test o f 200 psi is too m u c h for many existing systems. We risk doing more ha rm than good with the test. Fifty psi in excess of normal system pressure shonld be plenty for an exist ing system.

Tile third reason is to clarify wha t was m e a n t by the C o m m i t t e e in the exist ing Exception No. 3 as to the phrase, "such as relocated drops." It is ou r opinion that this was in tended to apply to any small port ion of a sprinkler system, but Authori t ies Having Jurisdict ion are i n t e r p r e t i n g it as o n l y small vertical por t ions since the only example is vertical. Our new Exception No. 3 defines small and does away with amb iguous examples . COMMITTEE ACTION: Accept in Principle.

I 1. In Exception No. 1 revise the term "working pressures" to "system working pressures" in the first line and revise the term "normal working pressure" to "system working pressure" in the last line.

2. R e n u m b e r existing Exception No, 3 as Exception No. 5 and revise the term "normal working pressure" to read "system working pressure."

3. Add a new Exception No. 3 to read: "Modifications affecting 20 or f ewer spr inklers shall no t require

testing in excess o f system working pressure." 4. Add a new Exception No. 4 to read: "Where addit ion or modif icat ion is made to an existing system

affecting more than 20 sprinklers, the new port ion shall be isolated and tested at not less than 200 psi for 2 hours."

5. Delete existing Sections 10-2.2.1.1 and 10-2.2.1.2 o f the Preprint and add a new Exception No. 6 to Section 10-2.2.1 to read as follows:

"In buried pipe, leakage shall be permit ted. The a m o u n t of leakage at the jo ints shall not exceed two quar ts per hour (1.89 L / h ) per 100 gaskets or jo ints irrespective of pipe diameter . Tile a m o u n t o f allowable leakage specified in 10-2.8.2.3.2 shall be permit ted to be increased by one fluid ounce per inch valve d iameter per hou r ( 3 0 m l / 2 5 m m / h ) for each metal seated valve isolating the test section. If d D' barrel hydrants are tested with the main valve open. so the hydrants are under .pressure , an addit ional five ounces per minu te (150 m l / m i n ) leakage is permit ted for each hydranc The a m o u n t of leakage in buried piping shall be measured at the specified test pressnre by p u m p i n g fi'om a calibrated container ," COMMITTEE STATEMENT: 1 and 2. These are editorial changes .

3 and 4. These actions more appropriately address the submit ter ' s concerns ,

5. This action corrects an existing conflict in tile Preprint . NUMBER OF COMMITTEE MEMBERS ELIGIBLE T O VOTE: 26 VOTE O N COMMITTEE ACTION:


EXPLANATION OF NEGATIVE: BAHADORI: Add the following to Except ion No. 4: "or 50 psi in excess of working pressure if working pressure is over

150 psi." The r equ i r emen t for testing 50 psi in excess of working pressure if

working pressure is over 150 psi, is only in Exce )tion No. 1. If left in this manne r , it could be cons t rned that when add t o n s are made to systems with working pressures in excess of 150 psi, tlae max i l num testing pressure is 200 psi.

• T i (Group 1) or Extra Hazard (Group 2) sprinkler protecuon, h s comment , if accepted, will make the classification of mercantile occupancies involving the sale of furniture with foam plastic cushioning consistent ~ith the classification for storage occupancies involving furniture with foam plastic cushioning•

Polyurethane foam, which is the cushioning material for upholstered furniture, ignites readily, and produces extreme heat and toxic gases. Uphols tered fllrniture sales areas are usually quite congested with a high fire load. Once ignited, upholstered furniture in a mercantile sales floor area will spread rapidly. The rapid fire spread and high heat product ion has the potential for overwhelming an Ordinary Hazard (Group 2) sprinkler system design. In addition, the large volume of thick, black, toxic smoke will quickly obscure the means of egress for building occupants and creates a serious hazard for responding firefighters. By classifying upholstered furniture mercanti le occupancies as Extra Hazai'd (Group 1), a greater volume of water will be applied to control both the fire spread and the smoke propagation.

"A-4-5.3.2 The expans ion charnber needs to be prepressurized to be of any value. T he following formula can be used to size the expansion c h a m b e r and de te rmine the pressure for precharging. This formula assmnes that an air pocket will be left at the end o f the antifi 'eeze port ion of the system after filling. Tiffs air pocket will act like a cushion as pressures change with t empera ture . Do not use this formula if yore- p rocedures call for allowing the air to escape while filling the system with antifreeze.

In o rde r to get the best use o f the formula, a s sume a precharge pressure for the tank and a vo lume of the tank. Calculate the m a x i m u m pressure. If the pressure is reasonable (within the limits o f the system componen t s ) , use that size tank and that pressure. If the pressure calculated is not reasonable, then pick a larger tank or a h igher precharge pressure and run the calculation again."

13- 251 - ([A-4-5.3.2] A-3-5.3.2): Accept in Principle SUBMITTER: Greg Cagle, Midland Automat ic Sprinkler Co., Inc. COMMENT ON PROPOSAL NO: 13-291 RECOMMENDATION: The proposed formula for sizing expans ion chambe r s should be adopted . SUBSTANTIATION: The Commi t t ee stated, "Submitter is encouraged to submi t addit ional information." I have provided addit ional technical informat ion in suppor t o f the proposed form u la.

While it would be desirable to have a s impler formula for sizing expans ion chambers , this is probably not possible. The reason is that any o f the following factors can affect the m i n i m u m required size by literally a factor of 10 or more:

• Capacity of the system. • T e m p e r a t u r e range in the area where the antifreeze system is

installed. • T e m p e r a t u r e range in the area where the expans ion c h a m b e r is

installed. • Water supply static presstn'e. • Level o f precharge pressurization on tim expans ion chamber . Accounting for these factors is therefore very important. This is

the reason for the level of complexi ty of the proposed sizing formula .

These factors are of seconda D' importance, but do nonethe less have some effect on the result:

• Type o f antifi-eeze used. • Antifreeze concentra t ion. These do not appear in tlae formula directly, but are necessa D' ira

order to de te rmine D E and D H, wlfich in turn de te rmine AL, the ~oltune by which the antifreeze solution expands across the tempera ture range.

Lastly, the original proposal did not men t ion this, but it might be worthwhile to cons ider requi r ing an informative placard similar to the hydraulic placard to be placed at the antifreeze control riser stating the capacity o f the system, type o f antifreeze and concent ra t ion needed , and the expans ion chamb e r size and pressure rat ing calculated for the system.

Note: Suppor t ing material available for review at NFPA Headqua r t e r s . COMMITTEE ACTION: Accept in Principle.

1. In Section 4-5.3.2 add the term "listed" to the second sen tence so it reads as follows:

"A listed expans ion chamber . . . " 2. Add append ix material to read as follows: "A-4-5.3.2. O n e me thod for sizing the c h a m b e r is as follows.

This is one formula t ion of tile ideal gas law from basic ch em i su T. The a m o u n t of air in the expans ion c h a m b e r will not change over time. The pressure, tempera ture , and volume of the air at different t imes will be related in accordance with this formula.

NFPA 13 - - A 9 9 ROC

The antifreeze in the sys. tern is essentially incompressible, so the air volume in the expansion chamber will decrease by the same amount the antifreeze expands.

(3) We are assuming there is no trapped air in the system piping, so the only air in the system is in the expansion chamber. This is a conservative assumption, since more air is better. In reality, there will be at least some trapped air. Only the air in the expansion chamber, though, can be relied upon to be there when needed.

(4) VEC : V 0

Atpre-charge, the chamber will be completely full of air.

13- 252 - (A-4-8.2.4): Accept in Principle SUBMITTER: R.A. Pridham, General Air Products Inc. COMMENT O N PROPOSAL NO: 13-1 RECOMMENDATION: A-4-8.2.4 Wording recommended:

A higher degree of preventing ice blocks can be achieved by lowering the dewpoint of the input air supply to the dry pipe system which is exposed to the lower temperatures of refrigerated space areas. The dewpoint (at final operating pressure) of the feed air supply, should be no greater than 20°Fbeiow the (sensible) temperature at which the refrigerated space is maintained. Packages used to supply the air to the refrigerated space piping systems should be FM approved. Using an approved compressor/dryer package the intake air does not need to be taken from the freezer room thus eliminating the negative mechanical consequences on the compressors a n d reducing installation cost. Properly designed systems produce the low dewpoints required without drawing air from the refrigerated spaces. The simplified mechanical arrangement of the approved compressor/dryer packages eliminate the need for various interpretations of specifications and trials of untested designs.

SUBSTANTIATION: The current piping arrangement shown in "Figure A-4.8.2.4 Refrigerator area sprinkler systems to minimize' the chances o f developing ice plugs." is confusing and ambiguous leading to significant misinterpretation of the equipment and installation leading to misapplication of product and exposure of facility owners to ice plug formation.

An FM approved compressor/dryer system is available which simplifies and rectifies the errors in application and minimizes/eliminates the exposure to ice formation. A technical report is available showing the practicality of using such a specifically designed package which has been tested and approved for the application. COMMIIWEE ACTION: Accept in Principle.

It is consistent with tile AISI Standards included in the Specialty Listing Criteria for Tension Only Bracing. Prestretching of the cable is required by the Building Code Standards for structural applications of steel cables. Prestretching addresses two issues. One is to eliminate pe rmanen t elongation of the cable each time it is loaded by eliminating pe rmanen t construction stretch and the o the r is to establish a verifiable modulus of elasticity. This requi rement specifically addresses the structu,~al integrity of the cable. Prestretching is required by the referenced Standards. Deletion of this wording would be

irresponsible and would be a solution to a problem that does not exist. COMMITTEE ACTION: Accept. NUMBER OF COMMITrEE MEMBERS ELIGIBLE TO VOTE: 20 VOTE ON COMMITTEE ACTION:

(c) Color coding or o ther cont inuous marking of each different size cable for field verification. SUBSTANTIATION: Deletion of the word "color" was not in response to a proposM that was submitted. It was proposed by a Committee Member during the deve lopment of Commit tee Proposal 13-289 (Log #CP8). The use of the words "Color Coding" was the result o f a properly submit ted proposal, subjected to public review and comment , and voted on at the Annual Meeting by the full NFPA. Membership. The. color, codin, g selves two. purposes. One Js to make it possible to dnstmguish the dnfferent sizes of cable in the field the o ther is to indicate that the cable is the special cable product that has been listed. The listed product must be prestretched to obtain a verifiable modulus of elasticity, as required by the specialty listing criteria. There is no o ther practical way to make these distinctions in the field and the only currently listed tension only bracing cable is color coded.

Deletion of this wording would be an open invitation to use unlisted materials and would be a solution to a problem that does not exist.

Adding the words "other continuous" before the word "marking" would provide for some other marking system, should another system be needed by some other entity. It should be noted, however, that cable can come in ten or twenty thousand foot spools. In order for any given section of cable from such spools to be marked for field identification, it would have to be continuous. COMMITTEE ACTION: Accept in Principle.

Accept the submitters proposed text with the following change: "(c) Color coding on- other continuou~ ~ marking of each

different size cable for field verification." COMMITTEE STATEMENT: The wording proposed by the submitter is considered to be too restrictive. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 20 VOTE ON COMMITTEE ACTION:

S U B S T A N T I A T I O N : 1. I believe tire thrus t of the Commi t t ee S ta tement on Proposal 1%250 (Log #161) is also applicable here. "These do not have a g r e e m e n t amongs t the eng inee r ing co m m u n i ty ... such limitations, if any, are best left up to the (AHJ's)."

2. While I favor remain ing silent on the issue at this time, if the Commi t t ee chooses to come out against a l imitation on flow velocity I believe the last sen tence should be removed. "Accuracy" (my dict ionary offers defini t ions such as "precision" and "exactness") is no t an appropr ia te word when discussing Hazen- Williams since, at best, it yields only a reasonable approx imat ion of the friction loss. Further , the reference to 32 f t / sec is supef l lnous and could raise ques t ions in a user 's mind about lower velocities and the unqual i f ied "velocities beyond" seems refutable.

3. If retained, should this merely apply to addit ions to exist ing systems? Why not make it a new 8-4.4.9?

4. Is there an implied corrflict with NFPA 750? COMMITTEE ACTION: Accept in Part.

1. Delete only the last two sentences of Section A-8-4.1. 2. Editorially, conf i rm the metric units in Figure A-8-2.4.

COMMITTEE STATEMENT: The intent o f the Commi t tee was trot to restrict water velocities. The submi t te r is correct in ques t ion ing the rational provided in the last two sentences.

13- 276 - (A-9-2.3.3): Reject SUBMITTER: Matthew T. Gustafson, Severna Park, MD COMMENT O N PROPOSAL NO: 13-1 RECOMMENDATION: Delete the current text and replace with the following:

The pressure tank should be adequate to supply the most hydraulically demanding demand areas of the sprinkler system. Where a standing charge of air or nitrogen is maintained in the tank to push the water out, the following formula should be used: P I V 1 = P2V2 where P 1 = the pressure of the initial charge of air, V 1 is the volume of the initial charge of air, P2 is the pressure of the charge of air when the tank is empty and V 2 is the volume of the tank. P2 should equal or exceed the highest sprinkler system demand calculated back to the connection to the pressure tank. If the air or nitrogen is supplied fi'om a separate tank, calculations or a discharge test may be needed to show that an adequate supply is available. SUBSTANTIATION: The current text assumes that the sprinkler system demand is entirely a fimction of the elevation of the highest branch line. COMMITTEE ACTION: Reject.

A-7-3.3.1.1 (231-A-7-1.1) Two direct comparisons between ordinary- tempera ture-and higb-temperature-~,-ated sprinklers are possible:

(a) With nonexpanded polyethylene 1-gal (3.8-L) bottles in corrugated cartons, a 3-ft (0.O-m) clearance, and tile same density, approximately the same number of sprinklers operated (9 at high temperature versus 7 at ordinary tempera ture) .

(h) With exposed, expandedpolys tyrene meat trays, a 9.5-ft (l.9-m) clearance, and the same density, three times as many ordinary-temperature-rated sprinklers opera ted ,as did high- temperature-rated sprinklers (11 at ltigh temperature versus 33 at ordinary temperature ).

The car toned plastics requirements of this s tandard are based to a great extent on test work that used a specific commodity - - 16-oz (0.473-L) polystyrene plastic jars individually separated by thin carton stock within a large corrugated carton [3~/~ fF (0.32 m 2 ) ].

An evaluation for each field situation mine the worst applicable hei.gbt- at can be e x p e c t e d t o appear m a have shown that considerably greater

demands occur where clearance is 10 ft (3.0 m) as compared to 3 ft (0.9 m), and where a pile is stable as compared to an unstable pile. Since a system is designed for a particular clearance, the system could be inadequate when significant areas do no t have piling to tile design height and larger clearances exist between stock and sprinklers. This can also be true where the packaging or ,arrangement is changed so that stable piling is created where unstable piling existed. Recognit ion of fllese conditions is essential to avoid installation of protect ion that is inadequate or becomes inadequate because of changes.

No tests were conducted simulating a peaked roof configuration. However, it is expec ted that tile principles of Section 7-3 still apply. The worst applicable height-clearance relationship dlat can be expected to occur should be found, and protection should be designed for it. If storage is all at the same height, the worst height-clearance relationship creat ing the greatest water demand would occur under tile peak. f f commodit ies are stored higher trader the peak, tile various height-clearance relationships should be tried and tile one creating tile greatest water demand used for designing protection.

A-7-3.3.2.2 (231-A-7-2.2) Test data is not available for all comhirmtions of commodities, storage heights, and clearances. Some of the protection criteria in this s tandard are based on extrapolations of test data for o ther commodit ies :rod storage cortfigurations, its well ,~; available loss data.

For example, there is very limited test data for storage of expanded plastics higher than 20 ft (6 m). Tile protection criteria in this s tandard for expaaded plastics higher than 20 ft (6 m) are extrapolated from test data for expanded plastics storage 20 ft (6 m) and less in height and test data for unexpanded plastics above 20 ft (6 m).

Further ex:mlples can be: found in the protection criteria for clearances up to 15 ft (4.6 m). Test data is limited for clearances greater than 10 ft (3.0 tr) . It should be ,assumed that, if protection is adequate for a given storage height in a building of a given heigbt, die same protection will protect storage of any lesser height in the same building, For example, protection adequate for 20-fi (6. l-m) storage in a 30-ft (10-m) building [10-ft (3.0-m) clearance] would also protect 15-ft (4.6-m) storage in a 30-ft (10- m) building [15-ft (4.6-m) clearance]. Therefore, the protection criteria in Table %2.2 for 15-ft (4.6-m) clearance are based on tile protection criteria for storage 5 ft (1.5 m) higher than the iudicated height with 10-ft (3.0-m) clearance.

Table 7-2.2 is based on tests that were conducted primarily widl higb-teuqmrature-rated, ~7/s~-in. (13.5-ram) orifice sprinklers. ()tiler tests have demon:.trated that where sprinklers are used with orifices greater flaan ~ 7/,z i~l. (13.5 ram), ordinary temperature sprinklers are acceptable.

A-7-5 (231-A-4-4) Idle pallet storage introduces a severe fire condition, Stacking idle pallets in piles is the best arrangel~nent of combustibles to promote rapid spread of fire, heat release, and complete combustion. Afterpal le ts are used for a short time in warehouses, they dry out a n d e d g e s become frayed and splintered. In this condit ion they are subject to easy ignition from a small ignition source. Again, high piling increases considerably both the challenge to sprinklers and the probability of involving a large number of pallets when fire occurs. Therefore, it is preferable to store pallets outdoors where possible. (ROC 13-173)

A fire in stacks of idle plastic or wooden pallets is one of tile greatest challenges to sprinklers. The undersides of the pallets "create a dry area on which a fire can grow and expand to other dry or partially wet areas. This process of j ump i ng to other dry, closely located, parallel, combustible surfaces continues until the fire bursts through the top of the stack. Once this happens, very little water is able to reach the base of the fire. The only practical me thod of s topping a fire in a large concentrat ion of pallets with ceiling sprinklers is by means of prewetting. In high stacks, this cannot be done without abnormally high water supplies. The storage of empty wood pallets should not be permit ted in an nnspr inklered warehouse containing other storage.

A-7-9.5 (231-A-9-1,231C-A-10-1, 13-A-5-3.5.1.1) ESFR sprinklers are designed to respond quickly to growing fires and deliver heavy discharge to suppress fires rather daan to control them. ESFR sprinklers shou ld not be relied on to provide suppression if they are used outside tlae design parameters.

While daese sprinklers are in tended primarily for use in high-pile storage situations, this section permits d~eir use and extension into adjacent portions of an occupancy that might have a lesser classification.

A-7-9.5.1.1 (231-A-9-1.3) Storage in single-story or multistory buildings can be permit ted, provided dae maximum cei l ing/ roof height as specified in Table 9-1.1 is satisfied for each storage area.

A-7-9.6.1 (13-A-5-3.6.1) If the system is a deluge type, daen ,all the need to be calculated even if they are located on

erent building faces.

A-7-9.5.2 (231-A-9-2, 231C-A-10-2.1) Design parameters were de te rmined from a series of full-scale fire tests that were conducted as a jo in t effort between Factory Mutual Research Corporation and the National Fire Protection Research Foundation. (Copies of the test reports are available from tire NFPRF.) (ROC 13-159)
