Specifies requirements for mass, quality and testing of zinc coatings and zinc/aluminium-alloy coatings on steel wire of circular or non-circular cross-section. The coatings are applied using a continuous process which may compromise immersion in molten metal or electrodeposition. The Standard applies to coatings on wire at its final size and specifies six coating mass classes. It specifies methods for the determination of coating mass and gives advice on the transport and storage of coated wires, and on coating selection for corrosion protection.
