CEN/TC 262/WG 14 - Guidelines and specifications for electrodeposited coatings of zinc or cadmium (including supplementary treatments) on iron or steel

ISO 2081:2018 specifies requirements for electroplated coatings of zinc with supplementary treatments on iron or steel. It includes information to be supplied by the purchaser to the electroplater, and the requirements for heat treatment before and after electroplating.
ISO 2081:2018 is not applicable to zinc coatings applied
-      to sheet, strip or wire in the non-fabricated form,
-      to close-coiled springs, or
-      for purposes other than protective or decorative.
ISO 2081:2018 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.

ISO 27830:2017 specifies the technical requirements of metallic and other inorganic coatings in order to develop consistent technical standards and establishes a standard format for designating the coatings. It applies to International Standards for electrodeposited, autocatalytic and vapour-deposited coatings.
Detailed technical requirements for individual coatings are not given in this document, but can be found in the International Standards listed in the Bibliography.
ISO 27830:2017 does not apply to thermally sprayed and porcelain enamel coatings.

ISO 2082:2017 specifies the requirements of electroplated coatings of cadmium with supplementary treatments on iron and steel. It includes information that is to be supplied by the purchaser to the electroplater, and describes coating requirements, including those for heat treatment before and after electroplating.
It is not applicable to coatings applied
-      to sheet, strip or wire in the non-fabricated form,
-      to close-coiled springs, or
-      for purposes other than protective, intrinsic lubricity, ductility, electrical conductivity and low contact resistance use.
ISO 2082:2017 does not specify requirements for the surface condition of the basis metal prior to electrodeposition with cadmium.
The coating thickness that can be applied to threaded components can be limited by dimensional requirements, including class or fit.
Additional information on corrosion resistance, rinsing and drying, processing parts in bulk and dyeing of chromate conversion coatings is given in Annex C.
