1 This International Standard specifies requirements for nickel plus chromium and for copper plus nickel plus chromium electrodeposited coatings that are applied to iron, steel, zinc alloys, copper and copper alloys, and aluminium and aluminium alloys to provide an attractive appearance and corrosion resistance. Several classes of coatings are provided that differ in thickness and type and guidance is given in selecting the coating class appropriate to the service conditions to which the coated product will be exposed.
2 This International Standard does not specify the surface condition required by the basis metal prior to the coating pro-cess.
3 This International Standard is not applicable to coatings on sheet, strip or wire in the unfabricated form nor to threaded fasteners or coil springs.
NOTES
4 ISO 4526 and ISO 6158 specify requirements for coatings of nickel and chromium used for engineering purposes.
5 Requirements for similar coatings, except for the absence of a top-coat of chromium, that can be used for appearance and protection are specified in ISO 1458.
