scope:

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 1000 MPa (or of corrdsponding hardness), because such steels are subject to hydrogen embrittlement.
