This International Standard specifies requirements for electro-plated coatings of zinc on iron or steel except for coatings applied:
a) to sheet, strip or wire in the unfabricated form;
b) to close-coiled springs;
c) for other than protective or decorative purposes.
It includes information to be supplied by the purchaser to the electroplater and requirements for heat treatment, both before and after electroplating.
The coating thickness that can be applied to threaded com-ponents may be limited by dimensional requirements, including class or fit. Attention is drawn to ISO 4042, which specifies the maximum thicknesses that can be applied to standard threads.
