AS/NZS 1789:2023
[Current]AS/NZS 1789:2023 adopts and modifies ISO 2081:2018, which specifies requirements for electroplated coatings of zinc with supplementary treatments on iron or steel. It includes information to be supplied by the purchaser to the electroplater, and the requirements for heat treatment before and after electroplating. This document does not specify requirements for the surface condition of the basis metal prior to electroplating with zinc.
