ISO 19598:2016适用于钢铁上无铬（VI）钝化的电沉积锌和锌合金涂层。锌合金涂层含有镍或铁作为合金元素（分别称为锌/镍和锌/铁涂层）。 涂层或涂层系统的主要用途是保护钢铁部件免受腐蚀。 ISO 19598:2016规定 -用于上述涂层系统的名称， -在规定的试验程序中达到的最低耐腐蚀性，以及 -要求的最小涂层厚度。

ISO 19598:2016 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. ISO 19598:2016 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.
