EN 12163:2011 (E) 8 4 Designations 4.1 Material 4.1.1 General The material is designated either by symbol or number (see Tables 1 to 7). 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 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 property requirements; H. Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirements; 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 k), 5 l) and 8.4]. 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. The product designation for products to this standard shall consist of: denomination (Rod); number of this European Standard (EN 12163); material designation, either symbol or number (see Tables 1 to 7); SIST EN 12163:2011

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 sub-sequent 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. NOTE 3 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. 7.3 Mechanical tests The sampling rate shall be in accordance with Table 19. Sampling units shall be selected from the finished products
