scope:

This standard specifies the technical delivery conditions for anodized aluminium and wrought aluminium alloy products which are widely used in the metalworking industry. Anodic oxidation generates an oxide coating on the surface of aluminium, which results in an increased resistance to corrosion. Furthermore, for certain suitable alloys anodizing preserves the decorative appearance obtained through pretreatment as in Table 1.

For the purposes of this standard, semi-finished aluminium products are:

- sheet, strip and plate as in DIN EN 485-1;

- cold drawn rod, bars and tube as in DIN EN 754-1;

- extruded rod, bars, tube and profiles as in DIN EN 755-1;

- extruded precision profiles as in DIN EN 12020-1.

This standard does not cover:

- products with oxide coatings produced by hard anodizing for technical purposes;

- products with oxide coatings produced by coil anodizing;

- products worked after anodizing.
