Scope and field of application

This International Standard specifies requirements for electroplated coatings of the intermetallic compound SnNi, with a composition of approximately 65 % (m/m) tin and 35 % (m/m) nickel.

It does not apply to

a) threaded components;

b) coatings on sheet, strip or wire in the unfabricated form, or on articles made from them;

c) coatings on coil springs;

d) 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).

1) MPa = 1 N/mm²
