BS EN ISO 2081:2018 Metallic and other inorganic coatings – Electroplated coatings of zinc with supplementary treatments on iron or steel

BS EN ISO 2081:2018

Metallic and other inorganic coatings. Electroplated coatings of zinc with supplementary treatments on iron or steel

Status : Current   Published : March 2018



What is this standard about?

It describes how to electroplate iron or steel with zinc coatings and supplementary treatments. 

Who is this standard for?

It’s widely used in manufacturing industries, specifically by applications’ suppliers in: 

  • Aerospace
  • Defence
  • Marine
  • Automotive
  • Rail
  • Electronics

Why should you use this standard?

It specifies requirements for electroplated coatings of zinc with supplementary treatments on iron or steel, including information to be supplied by the purchaser to the electroplater, and the requirements for heat treatment before and after electroplating. 

NOTE 1: This standard is not applicable to zinc coatings applied:

  • To sheet, strip or wire in the non-fabricated form
  • To close-coiled springs
  • For purposes other than protective or decorative

It does not specify requirements for the surface condition of the basis metal prior to electroplating with zinc. However, defects in the surface of the basis metal can adversely affect the appearance and performance of the coating. The coating thickness that can be applied to threaded components can be limited by dimensional requirements, including class or fit.

What’s changed since the last update?

This revised version is now more user-friendly, with updated normative references, clarifications made to the essential requirements and the removal of non-essential requirements. 

NOTE 2: Due to REACH Regulations, the use of hexavalent chromium compounds was banned in Europe from September 2017 except where specifically authorized. Alternative conversion coatings or substitutes can be used and are required to satisfy the corrosion requirements given in this document.
