Copper and copper alloys .Determination of copper content.Part 2: Electrolytic determination of copper in materials with copper content higher than 99,80 %; German version EN 16117-2:2012
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.
