4.1 Material
4.1.1 General
The material is designated either by symbol or by 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:
Material condition for the product as manufactured without specified mechanical properties;
Material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensile property requirements;
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.
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 Lsee Clause 5 list entry I), list entry m) and 8.41.
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);BS EN 12163 pdf free download.
