Electroplated coatings of tin-nickel alloy - Specification and test methods (ISO 2179:1986)
|Publication Date:||1 August 2016|
|ICS Code (Metallic coatings):||25.220.40|
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
