This International Standard specifies requirements for electro-deposited coatings (single-layer, double-layer or multi-layer) of gold and its alloys for electrical, electronic and other engineering applications on metallic and non-metallic materials.

In the case of double-layer and multi-layer coatings (see 10.11, the thickness requirements apply to the total gold coating, but the requirements for gold content apply to each layer.

It does not apply to coatings on screw threads [see ISO 4042, Threaded components — Electroplated coatings components (at present at the stage of draft11 or to coatings on sheet or strip in the unfabricated form.
