This Part of BS 4292 describes a method for specifying requirements for electrodeposited coatings (single-layer, double-layer or multilayer) of gold and its alloys on metallic and non-metallic materials for general decorative and/or protective purposes.
This standard is not applicable to:
- coatings on screw threads;
- coatings applied on sheet or strip in the unfabricated form;
- gold alloy coatings containing less than 58.5 % by mass of pure gold; or
- coatings containing less than 1 mg of gold per square centimetre of surface area.
In the case of double-layer and multilayer coatings, the thickness requirements apply to the total gold coating, but the requirements for gold content apply to each layer (see 7.1).
