Champ d’application

This standard applies to enterprises processing copper and copper alloy ingots, tubes, bars, wires, plates, strips, foils, and electrical copper wire rods. This standard is mandatory for energy consumption assessment and new project approvals in China. It does not apply to special processes such as powder metallurgy or vacuum melting.

Exigences techniques

The standard classifies energy consumption limits into three tiers: Tier 1, Tier 2, and Tier 3. Existing facilities must comply with Tier 3, while new and renovated/expanded facilities must meet Tier 2. It specifies comprehensive energy consumption limits for melting and casting processes, processing processes, and full processes. The requirements vary by product type and production method, such as extrusion and continuous casting. Manufacturers must strictly adhere to these tiered limits to maintain market access.

Méthodes d’essai

The standard outlines the statistical scope, including production, auxiliary, and affiliated systems. It provides a formula for calculating the comprehensive energy consumption per unit product, factoring in various energy conversion coefficients referenced in the appendices. Accurate calculation of comprehensive energy consumption is required for compliance reporting.
