Scope

This document stipulates the product classification of deformed aluminum and aluminum alloys, energy consumption limit levels per unit product, technical requirements, energy consumption statistical scope and calculation methods. This document is applicable to the calculation and assessment of unit product energy consumption (hereinafter referred to as energy consumption) of general industrial deformed aluminum and aluminum alloy ingots, plates, strips, foils, pipes, bars, profiles, wires, and forgings. and energy consumption control of new projects. This document does not apply to the calculation and assessment of energy consumption of aluminum and aluminum alloy products produced in special fields such as aviation and aerospace, as well as powder metallurgy, injection molding and other special processes.
