ISO 3613:2010 Metallic and other inorganic coatings - Chromate conversion coatings on zinc, cadmium, aluminium-zinc alloys and zinc-aluminium alloys - Test methods
WARNING — This International Standard calls for the use of substances and/or procedures that may be injurious to health if adequate safety measures are not taken. This International Standard does not address any health hazards, safety or environmental matters associated with its use. It is the responsibility of the user of this International Standard to establish appropriate health, safety and environmentally acceptable practices and take suitable actions for any national and international regulations. Compliance with this International Standard does not in itself confer immunity from legal obligations.
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 solvent-based polymers or wax.
