6.2 Hardness
The hardness properties of H... condition material shallconform to either the Brinell or the Vickers hardnessrequirements given for round or regular polygonal rodin Tables 9 to 16. The test shall be carried out inaccordance with 8.2. The test method to be used(Brinell or Vickers) shall be stated by the purchaser inthe order [see 5j)] unless the choice is to be left to thediscretion of the supplier.
NOTE No tensile requirements are specified in this standard. The
tensile values given in Tables 9 to 16 are approximate and aregiven for information only.
6.3 Resistance to dezincification
The depth of dezincification of CuZn36Pb2As(CW602N) products shall be:
for grade A: maximum 200 mm;
for grade B: mean not to exceed 200 mm andmaximum 400 mm [see 5k)].
The test shall be carried out in accordance with 8.3.
NOTE The as-supplied forging stock may not necessarily meetthis requirement unless suitably heat treated as described in 8.3.The test is intended to demonstrate that forgings produced from
the stock are capable of being processed so as to pass the testrequirement.
6.4 Dimensions and tolerances
6.4.1Diameter
The diameter shall conform to the tolerances given inTable 17 for class A, B or C, as appropriate to the order[see 5g)]. The diameter is calculated as the mean ofone or more pairs of measurements taken at rightangles at the same cross-section of the rod.
6.4.2Circularity
For round rod the deviation from circularity shall notexceed half the range of the tolerance on diameter
given in Table 17.
6.4.3Length
The forging stock shall conform to the tolerances onlength given in Table 18.
NOTE Subject to agreement between the purchaser and thesupplier, an agreed proportion of underlength rod may be includedin a consignment.
6.4.4Straightness
For round rod of diameter from 10 mm up to andincluding 50 mm, supplied to class C tolerances ondiameter and of length 1 000 mm or over, the deviationfrom straightness, defined as the curvature (depth of
arc) against a datum line when the product is lying flatin a horizontal plane, shall conform to the tolerancesgiven in Table 19.
7 Sampling
7.1 GeneralWhen required (e.g. if necessary in accordance withspecified procedures of a supplier's quality system, orwhen the purchaser requests inspection documentswith test results, or for use in cases of dispute), aninspection lot shall be sampled in accordance with 7.2and 7.3.
7.2 Analysis
The sampling rate shall be in accordance with Table 20.A test sample, depending on the analytical technique tobe employed, shall be prepared from each samplingunit and used for the determination of thecomposition.
NOTE 1 When preparing the test sample, care should be taken toavoid contaminating or overheating the test sample. Carbidetipped tools are recommended; steel tools, if used, should bemade of magnetic material to assist in the subsequent removal ofextraneous iron. If the test samples are in finely divided form(e.g. drillings, millings), they should be treated carefully with astrong magnet to remove any particles of iron introduced duringpreparation.
NOTE 2 In cases of dispute concerning the results of analysis,the full procedure given in ISO 1811-2 should be followed.
Results may be used from analyses carried out at anearlier stage of manufacturing the product, e.g. at thecasting stage, if the material identity is maintained andif the quality system of the manufacturer is certified as
conforming to EN ISO 9001 or EN ISO 9002.7.3 Hardness and dezincification resistance tests
The sampling rate shall be in accordance with Table 20.Sampling units shall be selected from the finishedproducts. The test samples shall be cut from thesampling units and may require heat treatment beforetesting. Test samples, and test pieces prepared fromthem, shall not be subjected to any further treatment,other than any machining operations necessary in thepreparation of the test pieces.
8 Test methods
8.1 AnalysisAnalysis shall be carried out on the test pieces, or testportions, prepared from the test samples obtained inaccordance with 7.2. Except in cases of dispute, theanalytical methods used shall be at the discretion ofthe supplier. For expression of results, the roundingrules given in 8.5shall be used.
NOTE In cases of dispute concerning the results of analysis,methods of analysis to be used should be agreed between thedisputing parties.
8.2 Hardness test
8.2.1General
When a hardness test is to be carried out the testsamples shall be prepared in accordance with 8.2.2and the test shall be carried out in accordancewith 8.2.3.

8.2.2Preparation of samples
8.2.2.1Non-precipitation hardening alloys
Test samples from alloys in Table 1 and in Tables 3to 8, obtained in accordance with 7.3, at the option ofthe supplier, shall be prepared in accordance witheither a) or b) as follows:
a) directly from forging stock produced by hotworking; or
b) from forging stock subsequently annealed at atemperature of not less than 500 8C for not lessthan 30 min.
NOTE The method of preparation of the test sample, i.e. whetherin accordance with a) or b) of8.2.2.1, should be stated togetherwith the hardness test results obtained, on any inspectiondocument supplied for the forging stock [see5m)].
8.2.2.2Precipitation hardening alloysTest samples from alloys in Table 2, obtained inaccordance with 7.3, shall be either:
a) used directly (i.e. in the as-delivered condition) forthe hardness test; or
b) solution heat treated and precipitation hardenedbefore testing
at the option of the purchaser [see 5i)], unless thechoice of sample preparation has been left to thediscretion of the supplier.
NOTE The method of preparation of the test sample, i.e. whetherin accordance with a) or b) of8.2.2.2, should be stated, togetherwith the hardness test results obtained, on any inspection
document supplied for the forging stock [see 5m)].
8.2.3Procedure for testing
Hardness shall be determined on a test piece cut fromthe test sample prepared in accordance with 8.2.2. Thetest shall be carried out in accordance with EN 10003-1or ISO 6507-1 as appropriate [see 5j)] and theimpression/indentation made on the cross-section ofthe test piece mid-way between the central axis andthe outside surface.
For the Vickers test in accordance with ISO 6507-1, atest force of 49,03 N, 98,07 N or 294,21 N shall be used.
For the Brinell test in accordance with EN 10003-1,
a 0,102F/D2 ratio of 10 shall be used, i.e. use a 1,00 mmdiameter ball and a force of 98,07 N, or a 2,5 mmdiameter ball and a force of 612,9 N, or a 10,0 mmdiameter ball and a force of 9 807 N.
NOTE When reporting hardness test results, reference should bemade to the method of preparation of the sample (see 8.2.2).
8.3 Dezincification resistance test
The test method given in EN ISO 6509 shall be used onthe test samples obtained in accordance with 7.3. Ifrequired, the test samples shall be heat treated in thetemperature range 450 8C to 550 8C before testing. Atest piece shall be taken from each test sample so asto expose a prepared cross-sectional surface to the test
solution.
At the completion of the test:
for grade A, the maximum depth ofdezincification in a longitudinal direction shall be
measured; for grade B, the mean depth of dezincification (inaccordance with annex B) and the maximum depthof dezincification, in a longitudinal direction, shall bemeasured.
8.4 Retests for analysis, hardness anddezincification resistance
If there is a failure of one, or more than one, of thetests in 8.1,8.2 or8.3, two test samples from the sameinspection lot shall be permitted to be selected forretesting the failed property (properties). One of thesetest samples shall be taken from the same samplingunit as that from which the original failed test piece
was taken, unless that sampling unit is no longeravailable, or has been withdrawn by the supplier.
If the test pieces from both test samples pass theappropriate test(s), then the inspection lot representedshall be deemed to conform to the particularrequirement(s) of this standard. If a test piece fails atest, the inspection lot represented shall be deemed notto conform to this standard.
8.5 Rounding of results
For the purpose of determining conformity to thecompositional limits specified in this standard, anobserved or a calculated value obtained from theanalysis shall be rounded in accordance with the
following procedure, which is based upon the guidancegiven in annex B of ISO 31-0:1992. It shall be roundedin one step to the same number of figures used toexpress the specified limit in this standard.
The following rules shall be used for rounding:
a) if the figure immediately after the last figure to beretained is less than 5, the last figure to be retainedshall be kept unchanged;
b) if the figure immediately after the last figure to beretained is equal to or greater than 5, the last figureto be retained shall be increased by 1.

B.1 Introduction
EN ISO 6509 specifies a method for the determinationof the maximum depth of dezincification of a brassspecimen. In accordance with the ruling given in 7.5.3of EN ISO 6509:1995, the following procedure extendsthe method to cover the determination of the meandepth of dezincification, in order to verify conformityto the dezincification resistance acceptance criteria forCuZn36Pb2As (CW602N) grade B products.
The principle of the method, the reagents, materialsand apparatus required, and the procedure for theselection and preparation of the test pieces, are all in
accordance with EN ISO 6509.
B.2 Procedure
Having determined the maximum depth ofdezincification in a longitudinal direction, inaccordance with clause 7of EN ISO 6509:1995(see 8.3), carry out the following operations todetermine the mean depth of dezincification.
Adjust the magnification of the microscope to suit thegeneral depth of dezincification and use the samemagnification for all measurements. Examine the entirelength of the section for evaluation, in contiguousvisual fields of the microscope.
NOTE To ensure the best accuracy of measurement, measure thelargest number of contiguous fields at the greatest possiblemagnification.
Using the measuring scale incorporated in themicroscope, measure and record the dezincificationdepth, i.e. the point of intersection of the scale and thedezincification front, [see Figure B.1a)] for eachcontiguous field. If the scale lies between twodezincified areas within the visual field, thedezincification depth shall be recorded as the point ofintersection of the scale and an imaginary line joiningthe extremities of the two dezincification frontsadjacent to the scale [see Figure B.1b)].
If there is no evidence of dezincification in the fieldexamined, or only one dezincified area which does notintersect the scale, then record the dezincificationdepth of that field as zero [see Figure B.1c)].
B.3 Expression of results
After measurement of all the contiguous fields alongthe entire length of the section for evaluation, calculateand report the mean dezincification depth as the sumof the measured depths for every field, divided by thenumber of contiguous fields examined.
