Material condition for the product as manufactured, without specified mechanical properties; R. Material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensile strength requirement; H. Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirement; S (suffix)
Material condition for a product which is stress relieved. NOTE Products in the M,
R. or H. material condition may be specially processed (i.e. mechanically or thermally stress relieved ) in order to lower the residual stress level to improve the resistance to stress corrosion and the dimensional stability on machining [see 5 h), 5 i) and 8.5]. Exact conversion between material conditions designated R. and H. is not possible. Except when the suffix S is used, 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. SIST EN 12167:2011

In view of this, mechanical property requirements for profiles are not specified in this standard but, if needed, are subject to agreement between the purchaser and the supplier [see 5 j)]. 6.2.2 Bar Bar in the R. or H. condition shall conform to the appropriate tensile or hardness requirements given in Tables 8 to 14. The tests shall be carried out in accordance with 8.2 or 8.3. 6.3 Resistance to dezincification The maximum depth of dezincification of CuZn38As (CW511L), CuZn36Pb2As (CW602N) and CuZn21Si3P (CW724R) products shall be 100 µm for thickness up to 40 mm. For greater sections the average depth of dezincification shall be less than 100 µm and the maximum measured value shall be less than 200 µm. The thickness is defined as the maximum ruling section. The test shall be carried out in accordance with 8.4. Products in CuZn21Si3P (CW724R) that have passed the test shall be marked with “Si”. NOTE Products in the alloys CuZn38As (CW511L) and CuZn36Pb2As (CW602N) may be subjected to heat treatment in the range 450 °C to 550 °C during manufacture. If the user needs to heat the material above 530 °C during subsequent processing then advice should be sought from the supplier. SIST EN 12167:2011

NOTE 1 If a purchaser requires the corners to have larger radii than those specified in Table 21, then the product is effectively a profile and the dimensions and tolerances of the corner radii required should be stated on the order/drawing. NOTE 2 Except in cases of dispute, the corners should be measured directly, either by use of a gauge or an optical projector. In cases of dispute, the method by optical projector should be used. 7 Sampling 7.1 General When required (e.g. if ne
