Over deze norm
NEN-EN-ISO 19598 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.
||Metallic coatings - Electroplated coatings of zinc and zinc alloys on iron or steel with supplementary Cr(VI)-free treatment
