    摘 要：對標準GB/T 16921—2005與國家電網有限公司[2018]979號文件中對金屬覆蓋層鍍銀厚度試驗要求與規(guī)定進行研究，提出在進行金屬覆蓋層銅鍍銀測試過程中，會因產品測試點不同部位、不同面、不同角度的變化，對銅鍍銀層厚度數(shù)值出現(xiàn)不一樣的結果，對調整測試儀器中的測量距離是否會改變銅鍍銀層厚度數(shù)值進行了分析研究，并給出了在測試金屬覆蓋層銅鍍銀產品時應當注意的事項與測試方法。

    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
