Scope

Scope: This document specifies the product classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of hand-operated wire cutters. This document is applicable to hand-operated wire cutters used for cutting ordinary carbon structural steel wire, cables, and hard copper wire. Main technical content: 1. Basic dimensions: The deviation of the total length of the product is limited, and the value change is much smaller than that of Chinese industry standards and Japanese standards. 2. Hardness: For the edge hardness of the wire cutter blade, on the one hand, the minimum hardness requirements are increased compared with Chinese, Japanese, and American standards; on the other hand, the hardness range is narrowed. 3. Life test: On the basis of industry standards, the number of usage cycles required for hand-operated wire cutters is increased.
