GB/T 13825-2008 "Metal coating ferrous metal material hot-dip galvanized layer, mass weighing method per unit area", stipulates the weighing method for the mass per unit area of ferrous metal hot-dip galvanized layer. The standard specifies the test principle, equipment, sample preparation, operation steps and result calculation. By standardizing the weighing process, the accurate measurement of the mass per unit area of the hot-dip galvanized layer is realized, which provides scientific quantitative means for evaluating the mass of the hot-dip galvanized layer and ensuring the protection performance.
