GB/T 18996-2021 is a silver content detection standard for silver alloy jewelry. The silver content is determined by sodium chloride or potassium chloride volumetric method (potential Titrimetric method). Silver content is a key indicator to measure the quality of silver alloy jewelry. The standard specifies the operation process in detail, and with the help of Potentiometric titration, poten-tiometry accurate determination, it can effectively eliminate interference and ensure accurate results. It is suitable for all kinds of silver alloy jewelry, providing strong support for mass control of its production and market circulation supervision, safeguarding consumer rights and interests, and promoting the healthy development of the silver alloy jewelry industry.
