This document specifies the classification, requirements, inspection rules, marking, Encasement, transportation and storage of silver and silver alloys/copper and copper alloy composite strips, and provides relevant test methods. It is suitable for the manufacture and inspection of silver and silver alloys, gold and gold alloys with double, triple or multi-layer composite strips with copper and copper alloys as the base layer. Normative reference documents include tensile test methods for metallic materials, Vickers Hardness test methods, chemical analysis methods for copper and copper alloys, grades and chemical composition standards for processed copper and copper alloys, Encasement, marking, transportation, storage and mass certificate standards for heavy non-ferrous metal processed products, and chemical analysis methods for gold, silver and precious metal alloys. The document does not contain specific terms or definitions, but describes the classification and composition of the tapes.
