ISO 2082:2008

ISO 2082:2008 specifies the requirements of electroplated coatings of cadmium with supplementary treatments on iron and steel. It includes information that is to be supplied by the purchaser to the electroplater, and describes coating requirements, including those for heat treatment before and after electroplating.
It is not applicable to coatings applied

to sheet, strip or wire in the non-fabricated form,
to close-coiled springs, or
for purposes other than protective, intrinsic lubricity, ductility, electrical conductivity and low contact resistance use.

ISO 2082:2008 does not specify requirements for the surface condition of the basis metal prior to electrodeposition with cadmium.
The coating thickness that can be applied to threaded components can be limited by dimensional requirements, including class or fit.
