Resumen:
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.
