Cupru şi aliaje de cupru. determinarea conţinutului de cupru. Partea 1: Determinarea prin electrogravimetrie a cuprului din aliaje cu un conţinut de cupru mai mic de 99,85 %
This European Standard specifies an electrolytic method for the determination of the copper content in copper materials with a copper content less than 99,85 % (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. Arsenic, antimony, bismuth and tin, if present, also interfere.
