6 Requirements
7 Sampling
6.1 Composition The composition shall conform to the requirements for the appropriate material given in Tables 1 to 8.
7.1 General When required (e.g. if necessary in accordance with specified procedures of a supplier's quality system, or when the purchaser requests inspection documents with test results, or for use in cases of dispute), an inspection lot shall be sampled in accordance with 7.2 and 7.3.
6.2 Hardness The hardness properties of H... condition material shall conform to either the Brinell or the Vickers hardness requirements given for round or regular polygonal rod in Tables 9 to 16. The test shall be carried out in accordance with 8.2. The test method to be used (Brinell or Vickers) shall be stated by the purchaser in the order [see 5j)] unless the choice is to be left to the discretion of the supplier. NOTE No tensile requirements are specified in this standard. The tensile values given in Tables 9 to 16 are approximate and are given for information only.
6.3 Resistance to dezincification The depth of dezincification of CuZn36Pb2As (CW602N) products shall be: Ð for grade A: maximum 200 mm; Ð for grade B: mean not to exceed 200 mm and maximum 400 mm [see 5k)]. The test shall be carried out in accordance with 8.3. NOTE The as-supplied forging stock may not necessarily meet this 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 the test requirement.
6.4 Dimensions and tolerances 6.4.1 Diameter The diameter shall conform to the tolerances given in Table 17 for class A, B or C, as appropriate to the order [see 5g)]. The diameter is calculated as the mean of one or more pairs of measurements taken at right angles at the same cross-section of the rod. 6.4.2 Circularity For round rod the deviation from circularity shall not exceed half the range of the tolerance on diameter given in Table 17. 6.4.3 Length The forging stock shall conform to the tolerances on length given in Table 18. NOTE Subject to agreement between the purchaser and the supplier, an agreed proportion of underlength rod may be included in a consignment.
6.4.4 Straightness For round rod of diameter from 10 mm up to and including 50 mm, supplied to class C tolerances on diameter and of length 1 000 mm or over, the deviation from straightness, defined as the curvature (depth of arc) against a datum line when the product is lying flat in a horizontal plane, shall conform to the tolerances given in Table 19.
BSI 1998
7.2 Analysis The sampling rate shall be in accordance with Table 20. A test sample, depending on the analytical technique to be employed, shall be prepared from each sampling unit and used for the determination of the composition. NOTE 1 When preparing the test sample, care should be taken to avoid contaminating or overheating the test sample. Carbide tipped tools are recommended; steel tools, if used, should be made of magnetic material to assist in the subsequent removal of extraneous iron. If the test samples are in finely divided form (e.g. drillings, millings), they should be treated carefully with a strong magnet to remove any particles of iron introduced during preparation. 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 an earlier stage of manufacturing the product, e.g. at the casting stage, if the material identity is maintained and if 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 finished products. The test samples shall be cut from the sampling units and may require heat treatment before testing. Test samples, and test pieces prepared from them, shall not be subjected to any further treatment, other than any machining operations necessary in the preparation of the test pieces.
8 Test methods 8.1 Analysis Analysis shall be carried out on the test pieces, or test portions, prepared from the test samples obtained in accordance with 7.2. Except in cases of dispute, the analytical methods used shall be at the discretion of the supplier. For expression of results, the rounding rules given in 8.5 shall be used. NOTE In cases of dispute concerning the results of analysis, methods of analysis to be used should be agreed between the disputing parties.
8.2 Hardness test 8.2.1 General When a hardness test is to be carried out the test samples shall be prepared in accordance with 8.2.2 and the test shall be carried out in accordance with 8.2.3.
Page 6 EN 12165:1998
8.2.2 Preparation of samples
NOTE The method of preparation of the test sample, i.e. whether in accordance with a) or b) of 8.2.2.1, should be stated together with the hardness test results obtained, on any inspection document supplied for the forging stock [see 5m)].
8.2.2.2 Precipitation hardening alloys Test samples from alloys in Table 2, obtained in accordance with 7.3, shall be either: a) used directly (i.e. in the as-delivered condition) for the hardness test; or b) solution heat treated and precipitation hardened before testing at the option of the purchaser [see 5i)], unless the choice of sample preparation has been left to the discretion of the supplier. NOTE The method of preparation of the test sample, i.e. whether in accordance with a) or b) of 8.2.2.2, should be stated, together with the hardness test results obtained, on any inspection document supplied for the forging stock [see 5m)].
8.2.3 Procedure for testing Hardness shall be determined on a test piece cut from the test sample prepared in accordance with 8.2.2. The test shall be carried out in accordance with EN 10003-1 or ISO 6507-1 as appropriate [see 5j)] and the impression/indentation made on the cross-section of the test piece mid-way between the central axis and the outside surface. For the Vickers test in accordance with ISO 6507-1, a test 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 mm diameter ball and a force of 98,07 N, or a 2,5 mm diameter ball and a force of 612,9 N, or a 10,0 mm diameter ball and a force of 9 807 N. NOTE When reporting hardness test results, reference should be made 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 on the test samples obtained in accordance with 7.3. If required, the test samples shall be heat treated in the temperature range 450 8C to 550 8C before testing. A test piece shall be taken from each test sample so as to expose a prepared cross-sectional surface to the test solution.
9 Declaration of conformity and inspection documentation 9.1 Declaration of conformity When requested by the purchaser [see 5l)] and agreed with the supplier, the supplier shall issue for the products the appropriate declaration of conformity in accordance with EN 1655. 9.2 Inspection documentation When requested by the purchaser [see 5m)] and agreed with the supplier, the supplier shall issue for the products the appropriate inspection document in accordance with EN 10204.
10 Marking, labelling, packaging Unless otherwise specified by the purchaser and agreed by the supplier, the marking, labelling and packaging shall be left to the discretion of the supplier [see 5n)]. BSI 1998

8.2.2.1 Non-precipitation hardening alloys Test samples from alloys in Table 1 and in Tables 3 to 8, obtained in accordance with 7.3, at the option of the supplier, shall be prepared in accordance with either a) or b) as follows: a) directly from forging stock produced by hot working; or b) from forging stock subsequently annealed at a temperature of not less than 500 8C for not less than 30 min.
At the completion of the test: Ð for grade A, the maximum depth of dezincification in a longitudinal direction shall be measured; Ð for grade B, the mean depth of dezincification (in accordance with annex B) and the maximum depth of dezincification, in a longitudinal direction, shall be measured. 8.4 Retests for analysis, hardness and dezincification resistance If there is a failure of one, or more than one, of the tests in 8.1, 8.2 or 8.3, two test samples from the same inspection lot shall be permitted to be selected for retesting the failed property (properties). One of these test samples shall be taken from the same sampling unit as that from which the original failed test piece was taken, unless that sampling unit is no longer available, or has been withdrawn by the supplier. If the test pieces from both test samples the appropriate test(s), then the inspection lot represented shall be deemed to conform to the particular requirement(s) of this standard. If a test piece fails a test, the inspection lot represented shall be deemed not to conform to this standard. 8.5 Rounding of results For the purpose of determining conformity to the compositional limits specified in this standard, an observed or a calculated value obtained from the analysis shall be rounded in accordance with the following procedure, which is based upon the guidance given in annex B of ISO 31-0:1992. It shall be rounded in one step to the same number of figures used to express the specified limit in this standard. The following rules shall be used for rounding: a) if the figure immediately after the last figure to be retained is less than 5, the last figure to be retained shall be kept unchanged; b) if the figure immediately after the last figure to be retained is equal to or greater than 5, the last figure to be retained shall be increased by 1.

Annex A (informative) Bibliography
Annex B (normative) Determination of mean depth of dezincification B.1 Introduction EN ISO 6509 specifies a method for the determination of the maximum depth of dezincification of a brass specimen. In accordance with the ruling given in 7.5.3 of EN ISO 6509:1995, the following procedure extends the method to cover the determination of the mean depth of dezincification, in order to conformity to the dezincification resistance acceptance criteria for CuZn36Pb2As (CW602N) grade B products.
B.2 Procedure Having determined the maximum depth of dezincification in a longitudinal direction, in accordance with clause 7 of EN ISO 6509:1995 (see 8.3), carry out the following operations to determine the mean depth of dezincification. Adjust the magnification of the microscope to suit the general depth of dezincification and use the same magnification for all measurements. Examine the entire length of the section for evaluation, in contiguous visual fields of the microscope. NOTE To ensure the best accuracy of measurement, measure the largest number of contiguous fields at the greatest possible magnification.
Using the measuring scale incorporated in the microscope, measure and record the dezincification depth, i.e. the point of intersection of the scale and the dezincification front, [see Figure B.1a)] for each contiguous field. If the scale lies between two dezincified areas within the visual field, the dezincification depth shall be recorded as the point of intersection of the scale and an imaginary line ing the extremities of the two dezincification fronts adjacent to the scale [see Figure B.1b)]. If there is no evidence of dezincification in the field examined, or only one dezincified area which does not intersect the scale, then record the dezincification depth of that field as zero [see Figure B.1c)]. B.3 Expression of results After measurement of all the contiguous fields along the entire length of the section for evaluation, calculate and report the mean dezincification depth as the sum of the measured depths for every field, divided by the number of contiguous fields examined.
NOTE The locations for the measurement of dezincification depth, in three different cases, are marked X.

4.1.1 General The material is designated either by symbol or number (see Tables 1 to 8). 4.1.2 Symbol The material symbol designation is based on the designation system given in ISO 1190-1. NOTE Although material symbol designations used in this standard might be the same as those in other standards using the designation system given in ISO 1190-1, the detailed composition requirements are not necessarily the same.
4.1.3 Number The material number designation is in accordance with the system given in EN 1412. 4.2 Material condition For the purposes of this standard, the following designations, which are in accordance with the system given in EN 1173, apply for the material condition: M
H...
Material condition for the product as manufactured without specified mechanical properties; Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirements.
NOTE Products in the H... condition may be specified to Brinell or Vickers hardness. The material condition designation H... is the same for both hardness test methods.
Material condition is designated by only one of the above designations. 4.3 Product The product designation provides a standardized pattern of designation from which a rapid and unequivocal description of a product is conveyed in communication. It provides mutual comprehension at the international level with regard to products which meet the requirements of the relevant European Standard. The product designation is no substitute for the full content of the standard.

6 Requirements
7 Sampling
6.1 Composition The composition shall conform to the requirements for the appropriate material given in Tables 1 to 8.
7.1 General When required (e.g. if necessary in accordance with specified procedures of a supplier's quality system, or when the purchaser requests inspection documents with test results, or for use in cases of dispute), an inspection lot shall be sampled in accordance with 7.2 and 7.3.
6.2 Hardness The hardness properties of H... condition material shall conform to either the Brinell or the Vickers hardness requirements given for round or regular polygonal rod in Tables 9 to 16. The test shall be carried out in accordance with 8.2. The test method to be used (Brinell or Vickers) shall be stated by the purchaser in the order [see 5j)] unless the choice is to be left to the discretion of the supplier. NOTE No tensile requirements are specified in this standard. The tensile values given in Tables 9 to 16 are approximate and are given for information only.
6.3 Resistance to dezincification The depth of dezincification of CuZn36Pb2As (CW602N) products shall be: Ð for grade A: maximum 200 mm; Ð for grade B: mean not to exceed 200 mm and maximum 400 mm [see 5k)]. The test shall be carried out in accordance with 8.3. NOTE The as-supplied forging stock may not necessarily meet this 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 the test requirement.
6.4 Dimensions and tolerances 6.4.1 Diameter The diameter shall conform to the tolerances given in Table 17 for class A, B or C, as appropriate to the order [see 5g)]. The diameter is calculated as the mean of one or more pairs of measurements taken at right angles at the same cross-section of the rod. 6.4.2 Circularity For round rod the deviation from circularity shall not exceed half the range of the tolerance on diameter given in Table 17. 6.4.3 Length The forging stock shall conform to the tolerances on length given in Table 18. NOTE Subject to agreement between the purchaser and the supplier, an agreed proportion of underlength rod may be included in a consignment.
6.4.4 Straightness For round rod of diameter from 10 mm up to and including 50 mm, supplied to class C tolerances on diameter and of length 1 000 mm or over, the deviation from straightness, defined as the curvature (depth of arc) against a datum line when the product is lying flat in a horizontal plane, shall conform to the tolerances given in Table 19.
BSI 1998
7.2 Analysis The sampling rate shall be in accordance with Table 20. A test sample, depending on the analytical technique to be employed, shall be prepared from each sampling unit and used for the determination of the composition. NOTE 1 When preparing the test sample, care should be taken to avoid contaminating or overheating the test sample. Carbide tipped tools are recommended; steel tools, if used, should be made of magnetic material to assist in the subsequent removal of extraneous iron. If the test samples are in finely divided form (e.g. drillings, millings), they should be treated carefully with a strong magnet to remove any particles of iron introduced during preparation. 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 an earlier stage of manufacturing the product, e.g. at the casting stage, if the material identity is maintained and if 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 finished products. The test samples shall be cut from the sampling units and may require heat treatment before testing. Test samples, and test pieces prepared from them, shall not be subjected to any further treatment, other than any machining operations necessary in the preparation of the test pieces.
8 Test methods 8.1 Analysis Analysis shall be carried out on the test pieces, or test portions, prepared from the test samples obtained in accordance with 7.2. Except in cases of dispute, the analytical methods used shall be at the discretion of the supplier. For expression of results, the rounding rules given in 8.5 shall be used. NOTE In cases of dispute concerning the results of analysis, methods of analysis to be used should be agreed between the disputing parties.
8.2 Hardness test 8.2.1 General When a hardness test is to be carried out the test samples shall be prepared in accordance with 8.2.2 and the test shall be carried out in accordance with 8.2.3.
Page 6 EN 12165:1998
8.2.2 Preparation of samples
NOTE The method of preparation of the test sample, i.e. whether in accordance with a) or b) of 8.2.2.1, should be stated together with the hardness test results obtained, on any inspection document supplied for the forging stock [see 5m)].
8.2.2.2 Precipitation hardening alloys Test samples from alloys in Table 2, obtained in accordance with 7.3, shall be either: a) used directly (i.e. in the as-delivered condition) for the hardness test; or b) solution heat treated and precipitation hardened before testing at the option of the purchaser [see 5i)], unless the choice of sample preparation has been left to the discretion of the supplier. NOTE The method of preparation of the test sample, i.e. whether in accordance with a) or b) of 8.2.2.2, should be stated, together with the hardness test results obtained, on any inspection document supplied for the forging stock [see 5m)].
8.2.3 Procedure for testing Hardness shall be determined on a test piece cut from the test sample prepared in accordance with 8.2.2. The test shall be carried out in accordance with EN 10003-1 or ISO 6507-1 as appropriate [see 5j)] and the impression/indentation made on the cross-section of the test piece mid-way between the central axis and the outside surface. For the Vickers test in accordance with ISO 6507-1, a test 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 mm diameter ball and a force of 98,07 N, or a 2,5 mm diameter ball and a force of 612,9 N, or a 10,0 mm diameter ball and a force of 9 807 N. NOTE When reporting hardness test results, reference should be made 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 on the test samples obtained in accordance with 7.3. If required, the test samples shall be heat treated in the temperature range 450 8C to 550 8C before testing. A test piece shall be taken from each test sample so as to expose a prepared cross-sectional surface to the test solution.
9 Declaration of conformity and inspection documentation 9.1 Declaration of conformity When requested by the purchaser [see 5l)] and agreed with the supplier, the supplier shall issue for the products the appropriate declaration of conformity in accordance with EN 1655. 9.2 Inspection documentation When requested by the purchaser [see 5m)] and agreed with the supplier, the supplier shall issue for the products the appropriate inspection document in accordance with EN 10204.
10 Marking, labelling, packaging Unless otherwise specified by the purchaser and agreed by the supplier, the marking, labelling and packaging shall be left to the discretion of the supplier [see 5n)]. BSI 1998

8.2.2.1 Non-precipitation hardening alloys Test samples from alloys in Table 1 and in Tables 3 to 8, obtained in accordance with 7.3, at the option of the supplier, shall be prepared in accordance with either a) or b) as follows: a) directly from forging stock produced by hot working; or b) from forging stock subsequently annealed at a temperature of not less than 500 8C for not less than 30 min.
At the completion of the test: Ð for grade A, the maximum depth of dezincification in a longitudinal direction shall be measured; Ð for grade B, the mean depth of dezincification (in accordance with annex B) and the maximum depth of dezincification, in a longitudinal direction, shall be measured. 8.4 Retests for analysis, hardness and dezincification resistance If there is a failure of one, or more than one, of the tests in 8.1, 8.2 or 8.3, two test samples from the same inspection lot shall be permitted to be selected for retesting the failed property (properties). One of these test samples shall be taken from the same sampling unit as that from which the original failed test piece was taken, unless that sampling unit is no longer available, or has been withdrawn by the supplier. If the test pieces from both test samples the appropriate test(s), then the inspection lot represented shall be deemed to conform to the particular requirement(s) of this standard. If a test piece fails a test, the inspection lot represented shall be deemed not to conform to this standard. 8.5 Rounding of results For the purpose of determining conformity to the compositional limits specified in this standard, an observed or a calculated value obtained from the analysis shall be rounded in accordance with the following procedure, which is based upon the guidance given in annex B of ISO 31-0:1992. It shall be rounded in one step to the same number of figures used to express the specified limit in this standard. The following rules shall be used for rounding: a) if the figure immediately after the last figure to be retained is less than 5, the last figure to be retained shall be kept unchanged; b) if the figure immediately after the last figure to be retained is equal to or greater than 5, the last figure to be retained shall be increased by 1.

Annex A (informative) Bibliography
Annex B (normative) Determination of mean depth of dezincification B.1 Introduction EN ISO 6509 specifies a method for the determination of the maximum depth of dezincification of a brass specimen. In accordance with the ruling given in 7.5.3 of EN ISO 6509:1995, the following procedure extends the method to cover the determination of the mean depth of dezincification, in order to conformity to the dezincification resistance acceptance criteria for CuZn36Pb2As (CW602N) grade B products.
B.2 Procedure Having determined the maximum depth of dezincification in a longitudinal direction, in accordance with clause 7 of EN ISO 6509:1995 (see 8.3), carry out the following operations to determine the mean depth of dezincification. Adjust the magnification of the microscope to suit the general depth of dezincification and use the same magnification for all measurements. Examine the entire length of the section for evaluation, in contiguous visual fields of the microscope. NOTE To ensure the best accuracy of measurement, measure the largest number of contiguous fields at the greatest possible magnification.
Using the measuring scale incorporated in the microscope, measure and record the dezincification depth, i.e. the point of intersection of the scale and the dezincification front, [see Figure B.1a)] for each contiguous field. If the scale lies between two dezincified areas within the visual field, the dezincification depth shall be recorded as the point of intersection of the scale and an imaginary line ing the extremities of the two dezincification fronts adjacent to the scale [see Figure B.1b)]. If there is no evidence of dezincification in the field examined, or only one dezincified area which does not intersect the scale, then record the dezincification depth of that field as zero [see Figure B.1c)]. B.3 Expression of results After measurement of all the contiguous fields along the entire length of the section for evaluation, calculate and report the mean dezincification depth as the sum of the measured depths for every field, divided by the number of contiguous fields examined.
NOTE The locations for the measurement of dezincification depth, in three different cases, are marked X.
