22、steel, cadmium and their alloys) either as an end finish or as an intermediate layer for other coatings. They are intended to a) impart corrosion resistance, b) improve adhesion to paints and other organic finishes, c) facilitate cold-forming operations, such as wire drawing, tube drawing and extrus
23、ion, and d) modify surface frictional properties so as to facilitate sliding. Phosphate conversion coatings are produced by treatment with solutions, the main constituents of which are the appropriate dihydrogen orthophosphates. These coatings are applied principally to ferrous materials, aluminium,
24、 zinc and cadmium and differ in coating mass per unit area and apparent density, depending on a) the construction material and surface condition of the components, b) previous mechanical and chemical treatment of the components, and c) processing conditions for phosphating. All phosphate conversion
25、coatings are more or less porous but can be sealed substantially by subsequent sealing processes.

This International Standard does not address any h
27、ealth hazards, safety or environmental matters and legislations associated with its use. It is the responsibility of the producers, purchasers and/or user of this International Standard to establish appropriate health, safety and environmentally acceptable practices and take appropriate actions to c
28、omply with any national, regional and/or international rules and regulations. Compliance with this International Standard does not in itself confer immunity from legal obligations. 1 Scope This International Standard specifies requirements for the processing of ferrous metals, aluminium, zinc, cadmi
29、um 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 fini
