IS 1359 : 1992 Electroplated coatings of tin

1 Scope

1.1 This standard specifies the requirements for electroplatedtin coatings of not less than 99.5 percent tin applied tofabricated articles of Iron, Steel, Nickel alloys and Copper andcopper alloys containing more than 50 percent of copper. It alsocovers coatings brightened by fusion in hot oil afterelectrodeposition, the process being known as flow-brightening orflow melting.

1.2 This standard does not, however, cover coatings on:

a) threaded components;

b) tin-coated copper wire;

c) coatings on sheet, strip or wire in unfabricated form or onarticles made from them;

d) coatings in coil springs;

e) coatings applied by chemical means (Immersion, autocatalyticor electroless);

f) electroplating of steels with tensile strength greater than1000 Mpa (or of corresponding hardness); because such steels aresubject to hydrogen embrittlement and aluminium and zinc alloys.
