This International Standard applies to electrodeposited zinc and zinc-alloy coatings on iron and steel with Cr(VI)-free passivation. The zinc-alloy coatings contain nickel or iron as alloying elements (referred to as zinc/nickel and zinc/iron coatings, respectively).
The main purpose of the coatings or coating systems is protecting iron and steel components against corrosion.
This International Standard specifies
  • — the designations to be used for the above coating systems,
  • — the minimum corrosion resistance to be achieved in specified test procedures, and
  • — the minimum coating thicknesses required.
