GB/T 13912-2020 specifies the technical requirements and test methods for hot-dip galvanized coatings on steel components (with total content of other alloying elements not exceeding 2%). It is not applicable to specific products such as continuously produced sheets and wires. The technical requirements include indicators such as appearance, thickness, and adhesion. The testing covers uniformity of the coating, adhesion amount, and adhesion performance, requiring the use of instruments such as coating thickness gauges, spectrometers, and drop weight test devices. Standardized procedures such as the copper sulfate immersion method and the stripping method are also employed to complete the testing.
