DIN EN ISO 19598:2017-04

This International Standard applies 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 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. This International Standard has been prepared by Technical Committee ISO/TC 107 "Metallic and other inorganic coatings" in collaboration with Technical Committee CEN/TC 262 "Metallic and other inorganic coatings", the secretariat of which is held by BSI. The responsible German working committee is NA 062-01-76 AA "Chemische und elektrochemische Überzüge" ("Chemical and electrochemical coatings") at DIN Standards Committee Materials Testing (NMP).
