Introduction
Further work completed under this study has been a cent in;»
uation, of tests of fungus resistance of available plastic laminated
materials following the Petri~Dish culture test procedure as
outlined in the "Fuhginertness Requirement and rest, for use in
EIL-I-631A (as completed 29 January 1951)«, furnished by the Bureau
of Ordnance with letter dated 16 February 1951. Earlier woric
covering the phase of the study was reported in the First Quarterly
Report (pages 4-25), the Second Quarterly Report (pages 28-77)*
and the Third Quarterly Report (pages 124-136}*
' Materials
The materials evaluated in this study include the following
laminated, thermosetting, plastic materials as approved under the
following specificationst

Exper imenta! Procedure-
The experimental procedure has "been explained in u.etail in
the First Quarterly fieport, pages 5S6, and 7«
%yglaa ti_9h_£>j£ Jteffultg,
At the end of the 81 day incubation period, each specimen
wa/s examined separately for growth oh the surface and for growth
on the cut edges and rated as follows;
Observed Fungus growth on the specimen
No growth Traces of growth (*) Slight to moderate growth: partial coverage Moderate growths considerable coverage Abundant growths complete coverage
Rating
0 1 2 3 4
(*)Traces of growth are defined as scattered, sparse fungus growth such as might develop from an unusual mass of spores in the original inoculum, or upon an occasional extraneous bit of debris« (Contihous cobwebby growth extending over the entire surface or edge of the specimen, even though not necessarily obscuring the specimen, was rated as 23)
Table 19 pages 253 through 255, lists the observations on
the individual replicates of the unconditioned specimens and the
numeric rating of each replicate both for surface and edge growthe
Table" 20 pages 256 through 258, lists the observations on the
individual ^pliostes of the conditioned specimens and the numeric
rating of eaeh replicate both for surface and edge growth«.

Interpretation off Results for Determination off Eunginertness
For a material to "be considered funginert. it shall not
support fungus growth; this shall "be due to absence of nutritive
.substances in the material and not to presence of a fungistatio
agent« The absence of a fugitive fungistatio agent was determined,
from the results on the specimens which received the conditioning
of 6 hours at 85° G*
On the basis of the numeric rating of the fungus growth on
the six specimens for each sample of plastic laminate being
evaluatedj the following criteria were used for the various degrees
of fungus resistance;
^ i^Jl^&öfJd". *" wiiere a-fc least 2 of 3 specimens were rated 0 or 1 wherTtested as received and at least 2 of 3 specimens were rated 0 or 1 when tested after baing conditioned«
2) EMi!yjllLJ^iÄii.^5^A° ~ where at least 2 of 3 specimens were ra'ted 0 or i" when tested as received and at least 2 of 3 specimens wer3 not_ rated 0 or 1 when tested after being conditioned*
®) BSBiaSg nSu_3QQPtible ~ where at least 2 of 3 specimens were not rated 0"or*1 when tested as received and at least 2 of 3 specimens were not, rated 0 or 1 when tested after being conditioned»
Since it has not been determined whether these criteria will
b© applied to surface growth alone or to surface growth together
with edge growths separate ratings have been assigned to the
specimens based on surface growth alone and on surface and edge
growth considered t^gothea?»
-251-
Ia*)le 21 pages 259 and S60* lists' the classification, of the
plastic laminates, tested;, "based on the ratingd considering surface
growth, alone and on the ratings considering surface growth together;
with edge' growth,*

.Introduction
Wor-fc during this .period has liieren the testing of 34
additional plastic laminated materials for fungus resistance»
following the Humidity-Exposure Method as outlined in paragraph
4«2 of "Draft of BuOrd Specification 52T15 (Ord), rev, draft*
Rele-, of 15 August 1950", furnished by the Bureau of Ordnance
with letter dated 17 January 1951« Earlier work covering
this phase of the study was reported in the Second Quarterly
Report (pages 78-120) and the Third Quarterly Report (pages 137
- 201);
Materials
The materials evaluated in- this, study include the following
laminated, thermosetting, plastic materials as approved
under the following specifications:

Experimental Procedure
The experimental procedure has been explained in detail
in the Second, Quarterly Report, pages 78 through 81,
Evaluation of Results
At the end of the incubation period the watch glass \*?as
removed and the rack taken out of the jar. The separate
pieces of string (controls) vjere examined for fungus growth
(visible to the naked eye)« All of the controls included in
this set of tests developed profuse fungus growth*
Each of the 4 specimens, exposed without attached cotton
string, was examined (with the aid of a 7X "Flash-O-Lens"
magnifier) for fungus growth. The percentage of area covered
"by fungus growth was noted for each of the two surfaces,
two side edges, top edge, and "bottom edge»
Each of the 4 specimens, exposed with attached cotton
string was examined for fungus-growth (visible to the naked
eye)- extending from the cotton string» The maximum extent
of the fungus growth from point of contact with the string
was noted for .each of two surfaces and each of the two side
edges, of each specimen«
Table 22 pages 267 through 300, lists the observations
on the individual replicates.»
-264-
Interpretation of Results for Determination of Funginertne3S
For a material to be considered funginert it shall not
support fungus growth; this shall be due to absence of
nutritive substances in the material and not to presence of a
fungistatic agent. The absence of a fungistatio agent was
determined by the fungus growth extending from the cotton
string on those replicates exposed with string attached»
On the basis of the percentage of area covered by fungus
growth on four of the eight specimens and the extent of fungus
growth from a known nutrient source on the remaining four of th£
eight specimens for each sample of plastic laminate being
evaluated! the following criteria were »sea. for the various
degrees of fungus resistances
1) FUflGlNERJT - where none of the replicates; exposed without attached cotton string, shows more than 2fo fungus growth and where fungus growth extends at least 1 mm from the string on at least 2 of the 4 repli- cates exposed with cotton string attached»
2) FUI^^T^A/Tyrc- where none of the replicates, exposed ._.., . _ wi^tl0ui. attached cotton string, shows
-more that 2fo fungus growth and where fungus growth does not extend at least 1 mm from the_ string oh at least 2 of the 4 replicates exposed with cotton string attached« •
3) FUNGUS SUSCEPTIBLE - where at least one of the four replicates, exposed without attached .cotton string, shows more than 2fo fungus growtho
In table 22, pages 267 through 300 are listed the ratings
for the 34 plastic laminated materials reported in this
section« A separate page has been set aside for each „g^s,.
(
sample and eaeh page presents both the original data and the
fungus resistance rating both for surface growth and for edge
growth» 'The Humidity-exposure Method permits a separate
evaluation "based on the edge growth alone, hence the separate
ratings« In this method the edge growth is tsrao edge growth
in contrast to the Petri-dish Method where edge growth could
in reality be deriving its nourishment from the agar and
merely extending over the edges of the specimen»

:)•..• During the period covered by this Fourth Report, a
number of additional available the rmoset ting molded plastics
were. t§ste,d for fuhginer.tnes=s io.-llpwing the Petrx-dlsh, culture
test procedure äs outlined in the ^Funginentness Requirement
and Test, for use inM2X~I-631ii" (as completed 29 January
1-95-1 )•-, furnished "by the Bureau öf Ordnance with letter dated
16, February 1951» Earlier work covering this phase of the
study was reported in the Third Quartesjy Report (pages 2QS-
244).

Experimental Procedure
The experimental procedure used was the same as that used
in the Petri-dish funginertness tests of plastic laminates
except for the test specimens used«. The details of this
procedure are found in the First Quarterly Report of this
series. (See pages 556, and 70)
The specimens used in these tests were prepared as follows*
The thermosetting molding plt-stio, being tested, was molded
into discs of l/8" thickness in such diameters as to -305-
-., .«..-vT:: '?&-.; ;AA'V r../i:*^^*i&z^^'#izr^^1&<r&**-- •• s~****'~~*&~ -=v<-=*2v
allow subsequent cut tag of s$uar-e:s 1 ineh by I ineS. ff OB
the discs« This cutting: wa^s ;&one= using an 8" arbor tilt
sew equipped with a suitable cutting blade»
The re-sulting specimens (l/-8" x 1" x 1") were then
handled in. the same manner as- the plastic laminate specimens»
Evaluation of Results
At the end of the 21 day incubation period, each specimen
was examined separately for growth on the surface and for
growth on the cut edges and rated as follows:
Observed Fungus growth on the -.specimen
No growth Traces of growth (*) Slight to moderate growth: partial coverage Moderäte growth:, considerable coverage Abundant growth: complete coverage
.Rating
0 1 2 3 4
( ) Traces of growth are defined as scattered, sparse fungus growth such as might develop from an unusual mass of spores in the original inoculum, or upon an occasional extraneous bit of debris. (Continous cobwebby growth extending over the entire surface or edge of the specimen, even though not necessarily obscuring the specimen, was rated as 2»)
Table 24, pages 308 through 310, lists the observations on
the individual replicates of the unconditioned specimens and
numeric rating of each replicate both for surface and edge
growth. Table 25, pages 311 through 313, lists the
observations on the individual replicates of the conditioned
specimens and the numeric rating of each replicate both for
surface and edge growth,

Interpretation of ReauLts^lor Determination of Funginertness
For a material to be considered funginert it shall -not.
support fungus growth; this shall be due to :a3)senee, of
nutritive substances in the material and not. to presence of a
fungistatic agent» Ehe absence of a fugitive fungistatic ageht
was determined from the results on the specimens which recived
the conditioning of 6 hours a=t .85- C»
Oh the, basis of the numeric rating of the fungus growth on
the six "specimens for each sa:mple of plastic being evaluated,
the following criteria were, used for the various degrees of
fungus resistance:
1) tfunginert - where at least 2 of 3 specimens were rated 0 or 1 when tested as received and at least 2 of 3 specimens were rated 0 or 1 when tested after being bond it ionedo
*2) fUjgitive fungistatic, - where at least 2 of 3 specimens were"" rated 0 or i~when tested as received and at least 2 of 3 specimens were np_t_ rated 0 or 1 when tested after being conditioned^""
3) Fungus Susceptible * where at least 2 of 3 specimens were not rated ö or 1 when tested as received and at least" 2 of 3 specimens «ere not^ rated 0 or 1 when tested after being oonditione'dT
Since it has no.t been determined whether these criteria
will be applied to surface growth alone or to surface growth
together with edge growth, separate ratings have been assigned
to the specimens based on surface growth alone and on surface
and edge growth considered together«
Table 26, pages 314 and 315, lists the classification,
of the molded plastics tested, based on the rating con-
sidering surface growth alone and on the ratings considering
surface growth together with edge growth. ~307~

or P^RTLil COMPARISON OF KESUED S OBTAINED
BY THE TWO TEST METHD'DS
A total of 129 plastic laminated materia.ls have been
tested for resistance to fungus, growth usiixg both the Petri-
Dish Method and the Humidity-Exposure Method as supplied by
the Bureau of Ordnance» Observations and zcafeings of the
individual replicates of these 129 laminates have been reported
on previous pages of this report and in thes First, Second and
Third Quarterly Reportse
A preliminary comparison of 30 of these 1S9 laminates
has been reported in the SepondQuarterly iteport, pages 121
and 122o u.t\ additional 55 laminates are iöcLuded in the
Third Quarterly report» pages 245 through 247a The additional
34 laminates are included in this report, (Cable 27, pages
319 lists these additional 54 laminates arranged in decreasing
order of fungus resistance, as determined "By the Petri-Dish-
Method, considering surface growth alone«, ilso listed in table
27, are the corresponding results as obtained using the Humidity
Exposure Method»
This listing has oeen compiled using results of surface
growth Plone 'on unconditioned specimens) since it is not
felt that the edge growth obtained in the 3?efc:r?i-Dish Method
is comparable to that obtained in the Humiaifcy-SJxposure
Method-
No conclusions are being drawn from this listing until all
the laminates under best have oeen reported,
