Organization: ISO
Publication Date: 15 December 2010
Status: active
Page Count: 14
ICS Code (Surface treatment): 25.220.20
scope:

This International Standard 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 solventbased polymers or wax.
