UNI 5974-1967
Methods for chemical analysis of ferrous metal materials. Among wear-resistant white metals, lead alloy and tin are used for printing. Determination of antimony; copper; lead and tin in lead soldering alloys. electrolysis

Scope: The group of methods is applicable to the alloys considered in this unification having a copper content less than or equal to 10%: arsenic and bismuth must be absent, or present in traces, because they co-deposit with antimony. 2 Controlled potential electrolytic methods allow the determination of antimony (if the copper in the sample is not greater than 0.05 g), copper and lead, together or separately, and tin.
