Due to developing legislation, specific applications (see 4.3) may require restrictions in the chemical composition. In this case the limitations shall be specified in the ordering information (see Clause 5 list entry f)). 6.2 Mechanical properties Products whose shapes are other than round may be delivered in M material condition in accordance with an agreement between supplier and customer. The hardness properties of H. material condition shall conform to the Brinell hardness requirements given for forging stock with round cross-section in Tables 9 to 16. The test shall be carried out in accordance with 8.2. In case tensile properties are required for forging stock, rods in accordance with EN 12163 or EN 12164 should be used. 6.3 Resistance to dezincification The maximum depth of dezincification, in any direction, of CuZn38As (CW511L), CuZn36Pb2As (CW602N), CuZn32Pb2AsFeSi (CW709R), CuZn21Si3P (CW724R) and CuZn33Pb1AlSiAs (CW725R) products shall be 100 µm. For the alloys CuZn35Pb1,5AlAs (CW625N), CuZn33Pb1,5AlAs (CW626N) the maximum depth of dezincification, in any direction, shall be 200 µm. The test shall be carried out in accordance with 8.3. NOTE 1 Shape and distribution of ß phase aggregates can influence the dezincification resistance of products. Special requirements relating to shape and distribution of beta phase aggregates are subject to agreement between purchaser and supplier. NOTE 2 The as-supplied forging stock in alloys other than CuZn21Si3P (CW724R) 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 pass the test requirement. SIST EN 12165:2016
EN 12165:2016 (E) 13 6.4 Dimensions and tolerances 6.4.1 Diameter The diameter shall conform to the tolerances given in Table 17 for class A or class B, as appropriate to the order [see Clause 5 list entry h)]. 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 Deviation from circular form For round rod the deviation from circular form shall not exceed half the range of the tolerance on diameter given in Table 17. 6.4.3 Length The forging stock shall have length and length tolerances agreed between customer and supplier. 6.4.4 Straightness For round rod of diameter from 10 mm up to and including 50 mm 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 18. 6.5 Surface quality The surfaces shall be clean and smooth. The forging stock may have a superficial film of drawing lubricant or, if annealed or thermally stress relieved, a superficial, dull, iridescent oxide film, securely adherent on the surfaces. Discontinuous irregularities on the surfaces of the forging stock are permitted if they are within the dimensional tolerances. Special requirements (e.g. pickling, degreasing, etc.) relating to the surface quality shall be agreed between the purchaser and the supplier [see Clause 5, list entry j)]. 7 Sampling 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. 7.2 Analysis The sampling rate shall be in accordance with Table 19. 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. 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. In cases of dispute concerning the results of analysis, the full procedure given in ISO 1811-2 should be followed. SIST EN 12165:2016
EN 12165:2016 (E) 14 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 e.g. as conforming to EN ISO 9001. 7.3 Hardness and dezincification resistance tests The sampling rate shall be in accordance with Table 19. 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. In cases of dispute concerning the results of analysis, methods of analysis to be used shall be agreed between the disputing parties. For expression of results, the rounding rules given in 8.5 shall be used. 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

6 Requirements 6.1 Composition The composition shall conform to the requirements for the appropriate material given in Tables 1 to 8. Due to developing legislation, specific applications (see 4.3) may require restrictions in the chemical composition. In this case the limitations shall be specified in the ordering information (see Clause 5 list entry f)). 6.2 Mechanical properties Products whose shapes are other than round may be delivered in M material condition in accordance with an agreement between supplier and customer. The hardness properties of H. material condition shall conform to the Brinell hardness requirements given for forging stock with round cross-section in Tables 9 to 16. The test shall be carried out in accordance with 8.2. In case tensile properties are required for forging stock, rods in accordance with EN 12163 or EN 12164 should be used. 6.3 Resistance to dezincification The maximum depth of dezincification, in any direction, of CuZn38As (CW511L), CuZn36Pb2As (CW602N), CuZn32Pb2AsFeSi (CW709R), CuZn21Si3P (CW724R) and CuZn33Pb1AlSiAs (CW725R) products shall be 100 µm. For the alloys CuZn35Pb1,5AlAs (CW625N), CuZn33Pb1,5AlAs (CW626N) the maximum depth of dezincification, in any direction, shall be 200 µm. The test shall be carried out in accordance with 8.3. NOTE 1 Shape and distribution of ß phase aggregates can influence the dezincification resistance of products. Special requirements relating to shape and distribution of ß phase aggregates are subject to agreement between purchaser and supplier. NOTE 2 The as-supplied forging stock in alloys other than CuZn21Si3P (CW724R) 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 pass the test requirement. kSIST FprEN 12165:2015
FprEN 12165:2015 (E) 11 6.4 Dimensions and tolerances 6.4.1 Diameter The diameter shall conform to the tolerances given in Table 17 for class A or class B, as appropriate to the order [see Clause 5 list entry h)]. 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 Deviation from circular form For round rod the deviation from circular form shall not exceed half the range of the tolerance on diameter given in Table 17. 6.4.3 Length The forging stock shall have length and length tolerances agreed between customer and supplier. 6.4.4 Straightness For round rod of diameter from 10 mm up to and including 50 mm 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 18. 6.5 Surface quality The surfaces shall be clean and smooth. The rods may have a superficial film of drawing lubricant or, if annealed or thermally stress relieved, a superficial, dull, iridescent oxide film, securely adherent on the surfaces. Discontinuous irregularities on the surfaces of the rods are permitted if they are within the dimensional tolerances. Special requirements (e.g. pickling, degreasing, etc.) relating to the surface quality shall be agreed between the purchaser and the supplier [see Clause 5, list entry j)]. 7 Sampling 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. 7.2 Analysis The sampling rate shall be in accordance with Table 19. 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. 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. In cases of dispute concerning the results of analysis, the full procedure given in ISO 1811-2 should be followed. kSIST FprEN 12165:2015
FprEN 12165:2015 (E) 12 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 e.g. as conforming to EN ISO 9001. 7.3 Hardness and dezincification resistance tests The sampling rate shall be in accordance with Table 19. 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. In cases of dispute concerning the results of analysis, methods of analysis to be used shall be agreed between the disputing parties. For expression of results, the rounding rules given in 8.5 shall be used. 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 carr
