This standard is specifically designed for testing the mechanical performance of metal jewelry chains such as necklaces and bracelets. It specifies the method for conducting tensile tests on finished or semi-finished products to determine their maximum breaking force and the force at specific elongation levels. When performing tests according to this standard, the core testing instrument is an electronic tensile testing machine. This equipment must be capable of precisely controlling the loading speed and recording the force-displacement curve. Additionally, it must be equipped with specialized fixtures (such as hook-shaped clamps) that can securely hold delicate jewelry chains to ensure the validity of the tests. This method serves as an important technical basis for controlling jewelry quality and assessing its safety and durability in use.
