This standard specifies a detailed method for the determination of aluminum content in hot-dip galvanized aluminum alloy platings by chemical Titrimetric method, including principle, reagents, analytical steps, result calculation, precision, quality control and test report. The standard is applicable to steel wire platings with aluminum content ranging from 2.5% to 30%. This method forms a complex with metal ions in a standard solution of disodium ethylenediaminetetraacetate (EDTA) and uses a drop-back method to determine aluminum content, providing an accurate test method for quality control of hot-dip galvanized aluminum alloy steel wire products.
