This standard specifies the technical requirements and inspection methods for obtaining protective zinc coatings on metal workpieces through mechanical plating processes. It applies to mechanical zinc coatings on various types of metal workpieces, with core content including the classification and identification of coatings, requirements for substrate pretreatment, inspection of coating quality, and sampling rules, accompanied by detailed process procedures and technical parameters. The relevant test methods mentioned in the standard, such as the cross-cut test for evaluating coating adhesion, bending tests, impact tests, and salt spray tests (e.g., neutral salt spray tests) for assessing corrosion resistance, are all key inspection measures to ensure the quality of zinc coatings.
