Scope

Scope: This document specifies the evaluation index system, evaluation methods, and grade classification for the quality and enterprise standard level of electrical round copper rods. This document is applicable to the quality and enterprise standard level evaluation of electrical round copper rods. Relevant institutions can refer to it when conducting quality grading and enterprise standard level assessments, as well as "leader" evaluations and related certifications. Enterprises can also refer to this document when formulating their own enterprise standards. Main technical content: 4.2 Evaluation Index Classification The evaluation index system for the quality grading and "leader" evaluation of electrical round copper rods includes basic indicators, core indicators, and innovative indicators. Basic indicators include chemical composition, dimensional deviation, and surface quality. Core indicators include mechanical properties, torsional properties, and electrical properties. The core indicators are divided into three levels, including advanced level, which corresponds to the 5-star level in the enterprise standard ranking list; average level, which corresponds to the 4-star level in the enterprise standard ranking list; and benchmark level, which corresponds to the 3-star level in the enterprise standard ranking list.
