GB/T 2972-2016
ActiveTest method for uniformity of zinc coating on zinc-coated steel wire by the copper sulphate dip
镀锌钢丝锌层硫酸铜试验方法
Application Summary AI generated
This standard specifies a test method using repeated dips in a copper sulfate solution to assess the uniformity and thickness of the zinc coating on galvanized steel wire. It is applied in the manufacturing and quality control of zinc-coated steel wire products, such as those used in fencing, cables, and overhead conductors, to ensure the coating provides adequate corrosion protection. The method is primarily used in production testing and acceptance inspection within the steel wire and fastener industries.
