    Abstract: According to the standard GB/T 16921—2005 and State Grid Co., Ltd. [2018] No. 979, the test requirements and regulations of the silver plating thickness of the metal coating are studied. It is proposed that in the process of testing the copper silver plating of the metal covering layer, different results will appear on the thickness of the copper silver plating layer due to the changes in different parts, different sides and different angles of the product test points, and to analyze and study whether adjusting the measuring distance in the test instrument will change the thickness of the copper silver-plated layer, and give the matters and test methods that should be paid attention to when testing the copper silver-plated product with the metal covering layer.

    Key words: copper silver plating layer; part; angle; measuring distance
