38、04 EN ISO 19598:2016 (E)5 1 ScopeThis 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).

39、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

40、 coating thicknesses required.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
