EN ISO 19598 (ISO 19598:2016) AS
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.
