- Scope
- This standard specifies requirements for nickel+chromium and copper+nickel+chromium electroplating coatings on steel, zinc alloys, copper and copper alloys, aluminum and aluminum alloys to provide a decorative appearance and enhanced corrosion protection. It stipulates the identification of different thicknesses and types of coatings, and provides guidelines for the selection of coating identifications for electroplated products exposed to corresponding service environments. This standard does not specify the surface condition of the base metal before electroplating. This standard does not apply to the electroplating of unformed sheets, strips, and wires, nor does it apply to the electroplating on threaded fasteners or coil springs. GB/T 12600 specifies the requirements for copper + nickel + chromium plating on plastics. GB/T 9798 specifies the requirements for the same coating as the non-chrome-plated surface. GB/T 12332 and GB/T 11379 specify the requirements for engineering nickel and engineering chromium electroplating layers respectively.
