This International Standard specifies requirements for elec-troplated coatings of the intermetallic compound SnNi, with a composition of approximately 65 % (m/m) tin and 35 % (mim) nickel.
It does not apply to
a) threaded components;
b) coatings on sheet, strip or wire in the unfabricated form, or on artides made from them;
c) coatings on coil springs;
d) electroplating of steels with tensile strength greater than 1 000 MPa11 (or of corresponding hardness), because such steels are subject to hydrogen embrittlement (see 8.2).
