This International Standard specifies requirements for electroplated coatings of nominally pure tin on fabricated metal articles. 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 articles 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).
