本欧洲标准规定了用于测定铜含量的电解方法
铜含量高于99,80％（质量分数）的非合金铜材料
未锻造，锻造和铸造产品。
银，如果存在，共同存放，并以铜的形式报告。约有一半的硒和
目前碲会共存。铋如果存在也会干扰

This European Standard specifies an electrolytic method for the determination of the copper content of
unalloyed copper materials with a copper content higher than 99,80 % (mass fraction) in the form of
unwrought, wrought and cast products.
Silver, if present, is co-deposited and is reported as copper. Approximately one-half of any selenium and
tellurium present will co-deposit. Bismuth, if present, also interferes.
