Cupru şi aliaje de cupru. Determinarea conţinutului de cupru. Partea 2: Determinarea prin electrogravimetrie a cuprului din materiale cu un conţinut de cupru mai mare de 99,80 %
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 castings, wrought and unwrought 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.
