GB/T 17832-2021 《Silver jewellery alloys—Determination of silver—Volumetric (potentiometric) method using potassium bromide》 Related products
GB/T 17832-2021 is used for the detection of silver alloy jewelry. It uses the potassium bromide volumetric method to determine the silver content. The silver content determines the quality and value of silver alloy jewelry. This standard specifies the specific operation of the potassium bromide volumetric method Potentiometric titration, poten-tiometry, which can accurately determine the silver content in silver alloys. It is suitable for all kinds of silver alloy jewelry products, providing a reliable basis for production, Quality control and market transactions, protecting consumer rights and interests, and helping to standardize the order of the silver alloy jewelry industry.
