This document specifies requirements for hard anodic oxidation coatings on aluminium and its alloys, including test methods.

It also specifies the information to be supplied by the customer to the anodizer (see Annex A).

It is not applicable to coatings produced by processes such as those referred to as plasma electrolytic oxidation, micro-arc oxidation, plasma-chemical anodic oxidation, anodic spark deposition or spark anodizing.

This document specifies methods for the determination of

— the presence of colourless chromate conversion coatings,

— the presence of hexavalent chromium in colourless and coloured coatings on zinc or cadmium or aluminium-zinc (mass fraction of aluminium: 55 %, within a range of 54 % to 56 % mass fraction) and zinc-aluminium (mass fraction of aluminium: 5 %) alloys,

— the total chromium content per unit area on zinc and cadmium,

— the mass per unit area of both colourless and coloured coatings,

— the satisfactory adhesion of chromate conversion coatings, and

— the quality of chromate coatings.

These methods are applicable

— to colourless and coloured chromate conversion coatings containing trivalent and hexavalent chromium in varying proportions and produced by either chemical or electrochemical processes, and

— only to chromate coatings that are free from any supplementary coatings, such as oil, water or solvent-based polymers or wax.
