Metallic and other inorganic coatings -- Chromate conversion coatings on zinc, cadmium, aluminium-zinc alloys and zinc-aluminium alloys -- Test methods
This standard was last reviewed and confirmed in 2013. Therefore this version remains current.
ISO 3513:2010 specifies methods for the determination of the presence of colourless chromate conversion coatings, 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, total chromium content per unit area on zinc and cadmium, mass per unit area of both colourless and coloured coatings, satisfactory adhesion of chromate conversion coatings, and quality of chromate coatings.
