The materic. number d-signation is in accordance with the system given in EN 1412. 4.2 Product The product designation provides a standardized pattern of designation fr
34、om 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
35、the standard. The product designation for products to this standard shall consist of: - denomination (scrap); - number of this European Standard (EN 12861); - material designation, either symbol or number (see tables in annexes B to E); - diameter class, if specified (see tables in annexes B to E).
36、The derivation of a product designation is shown in the following example. EXAMPLE: Scrap conforming to this standard, in material designated either S-Cu-1 or CSO26A, diameter class A, shall be designated as follows: Scrap EN 12861 - S-Cu-1 - A or Number Denomination Material of designation this Eur
