ISO 9717-2010 pdf free.Metallic and other inorganic coatings – Phosphate conversion coating of metals. ISO 9717 specifies requirements for the processing of ferrous metals, aluminium, zinc, cadmium and their alloys to produce coatings consisting essentially of inorganic phosphates, which are intended to be used in conjunction with supplementary treatments for the protection of the basis metal against corrosion and to provide anti-wear properties to sliding surfaces, adhesion to organic finishes and ease of cold-forming operations. 2 Normative references The following referenced documents are indispensable for the application of this document.

BS EN ISO 3613:2021 pdf free.Metallic and other inorganic coatings一Chromate conversion coatings on zinc, cadmium, aluminium-zinc alloys and zinc- aluminium alloys一Test methods. In the case of a cadmium substrate, observe the appearance of the spot for 1 mm. The formation of a dark or black stain at least 5 s after the application of the test solution shall be deemed to indicate the presence of a colourless chromate conversion coating. Black stain formation after more than I mm can be indicative of the presence of supplementary coatings, such as wax or oil. For comparison purposes, test an untreated surface similarly. Untreated zinc and cadmium surfaces, or the surfaces that have been treated for the chromate conversion coating but do not have a continuous coating, will react with the lead acetate solution to form a black stain on the untreated or bare zinc and cadmium surfaces almost immediately, within 2 s to 5 Sb after the application of the test solution. No significance is to be placed upon any differences in the reaction time to black-spot formation between 1 mm and 3 mm on a zinc substrate, or between 5 s and 60 s on a cadmium substrate, with a colourless…
