Defines the plating of a Zinc-Nickel (12% to 16%) alloy on mechanical parts and fasteners in steels (R[m] <= 1450 MPa), stainless steels (R[m] <= 1450 MPa), copper alloys, nickel alloys and aluminium alloys (not applicable for electrical components), as well as the passivation and lubricant finishing that can be associated to them.

This European Standard specifies the plating of a Zinc-Nickel (12%to 16%) alloy on mechanical parts and fasteners in steels ( R m≤1450MPa), stainless steels ( R m≤1450MPa), copper alloys, nickel alloys and aluminium alloys (not applicable for electrical components), as well as the passivation and lubricant finishing that can be associated to them. The Zinc-Nickel process is an electrolytic plating process under controlled current allowing to deposit a Zinc-Nickel layer from, most often, an alkaline electrolyte. Alkaline Zinc-Nickel is only considered in this standard.

The purpose of this standard is to give technical and quality requirements of Zinc-Nickel plating. It doesn’t give complete in-house process instructions, these shall be given in the manufacturers detailed process instructions.
