1.1 This standard covers the requirements of electrogalvanized coating on steel wires of cir-cular section in diameters from 0'2 mm up to and including 10 mm and lays down specifica-tions for:
a) mass of zinc coating,
b) uniformity of zinc coating, and
c) adhesion of zinc coating.
1.2 It also lays down methods of testing for these properties and provides for such testing to be carried out before and/or after the wire has been used for armouring, stranding, etc.
1.3 This standard makes no reference to the quality of wire itself. It does not apply to the articles made from wire which have been electro-galvanized after fabrication.
1.4 The relevant Indian Standard governing a particular type of wire should refer to this stan-dard for specifying the requirements of electro-galvanized zinc coating.
