It mainly applies to zinc and zinc alloy coating systems (zinc, zinc-nickel, zinc-iron) and cadmium, primarily intended for corrosion protection and other functional properties: It also specifies requirements and gives recommendations to minimize the risk of hydrogen embrittlement see 4.4 and Annex B. The requirements related to dimensional properties also apply to fasteners made of copper or copper alloys. This document specifies requirements for electroplated coatings and coating systems on steel fasteners.
