GB 1 2305.4 - 1990 "Test Methods for JINHE Gold Alloy Platings with Metal Coatings Part 5 Bonding Strength Test" standard specifies the bonding strength test method for gold and gold alloy platings. The standard applies to the determination of the bonding strength of metal platings for engineering, decoration and protection. The tests include sanding test, tape test, thermal shock test and bend test, which are designed to detect the adhesion of platings to the substrate. The specific method involves observing the blistering, disbonding, and detachment of platings under different conditions. The standard provides detailed test procedures and reporting requirements to ensure that the durability and performance of platings comply with relevant standards.
