UNI 5976-1967 Methods for chemical analysis of ferrous metal materials. Determination of copper in wear-resistant white metals, lead alloys for printing and tin-lead soldering alloys. controlled potential electrolysis
The method is applicable to the alloys considered in this unification, when lead constitutes the main component, with a copper content of 0.2%; silver and bismuth must be absent or present in traces, because they co-deposit with copper.
