This International Standard specifies requirements for elec-troplated coatings of nominally pure tin on fabricated metal artides. The coatings may be dull or bright as electroplated or may be flow-melted by fusion after electroplating.
It does not apply to
a) threaded components;
b) tin-coated copper wire;
c) coatings on sheet, strip or wire in unfabricated form, or on artides made from them;
d) coatings on coil springs;
e) coatings applied by chemical means (immersion, autocatalytic or "electroless");
f) electroplating of steels with tensile strength greater than 1 000 MPa1) (or of corresponding hardness), because such steels are subject to hydrogen embrittlement (see 8.2).
