Metallic Coatings – Electrodeposited zinc and zinc alloys on iron or steel with supplementary Cr (VI)-free treatment

This standard applies to electrically isolated and Cr (VI)-free and passivated zinc coatings on iron or steel. The coating may contain nickel as an alloying element or iron (Zinc-Nickel or Zinc-Iron). The main purpose of the application of coating sand coating systems is the corrosion of components of iron materials. This standard is defined for the above coating systems, the name sand sets minimum corrosion resistance described in test procedures, the required minimal thickness frim.
