ActiveTest methods for bare wires - Part 11: Test for adherence of coating
裸电线试验方法 第11部分：镀层附着性试验
Application Summary AI generated
This standard specifies the method for testing the adherence of metallic coatings on bare electrical wires, such as tin or silver plating on copper conductors. It is applied in the manufacturing and quality control of wires used in power cables, communication cables, and winding wires to ensure the coating does not peel or flake during bending or wrapping. The test is critical for verifying durability in electrical and electronic equipment where reliable conductivity and corrosion resistance are required.
