Abstract：The standards of pure precious metal products and the corresponding testing standards issued at home and abroad were summarized. The development history and current situation of precious metal products and their testing technical standards were reviewed. The differences of product standard parameters at home and abroad as well as the advantages and disadvantages of various testing technology methods were compared. The existing problems at present were analyzed and discussed. The development trend and hot spots in future were prospected.
