This standard specifies the comprehensive technical specifications and test methods for electroplating pure tin coatings on metal products, aiming to provide a quality basis for corrosion protection and improved solderability. The standard primarily covers the technical requirements for electroplating pure tin coatings, as well as key test methods to ensure their quality, involving core performance indicators such as coating thickness, adhesion strength, and corrosion resistance. Completing these tests requires corresponding professional instruments, such as metallographic microscopes or thickness gauges for measuring coating thickness, cross-cut testers or tensile testing machines for evaluating coating adhesion, and salt spray test chambers for examining corrosion resistance performance.
