Metallic and other inorganic coatings - Chromate conversion coatings on zinc, cadmium, aluminium-zinc alloys and zinc-aluminium alloys - Test methods

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.

Chromate conversion coatings on zinc, cadmium, aluminium-zinc alloys and zinc-aluminium alloys - Test methods

<p> La présente Norme internationale spécifie les méthodes pour la détermination - de la présence de couches de conversion au chromate incoloresi); - de la présence et de la quantité de chrome hexavalent dans les couches colorées et incolores sur zinc, cadmium et alliages d'aluminium (55 % en masse)-zinc et de zinc-aluminium (5 % en masse); - de la teneur totale en chrome par unité de surface sur zinc et cadmium; - de la masse par unité de surface des couches incolores et colorées; - du degré d'adhérence des couches de conversion au chromate; - de la qualité de la couche de conversion au chromate. Ces méthodes s'appliquent - aux couches de conversion au chromate incolores et colorées contenant du chrome trivalent et hexavalent en diverses proportions et produites par un procédé chimique ou électrochimique; - uniquement aux couches au chromate exemptes de tout revêtement supplémentaire tel que huile, polymère à base d'eau ou solvant, ou cire. </p>
