Scope

This document stipulates the limit levels, technical requirements, statistical scope and calculation methods for energy consumption per unit product of copper and copper alloy processed materials (hereinafter referred to as energy consumption). This document is applicable to the calculation and assessment of unit product energy consumption of manufacturing enterprises that process copper and copper alloy ingots (billets), pipes, rods, wires, plates, strips, foils, and electrical copper wire rods, as well as for new and improved construction. Energy consumption control for expansion projects. This document is not applicable to the calculation and assessment of energy consumption of copper and copper alloy processing materials produced by special processes such as powder metallurgy, vacuum casting, multi-stage aging, etc.
