Energy consumption limits per unit product for graphite and fluorite

1 Scope

GB 45549-2025 is the Chinese national standard on norm of energy consumption per unit production of graphite and fluorite, in the field of energy and heat transfer engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 28 March 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 April 2026. Classification: ICS 27.010, CCS F01. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the limit level, technical requirements, statistical scope and calculation of energy consumption per unit product (hereinafter referred to as energy consumption) of graphite and fluorite. method. This document is applicable to the calculation and assessment of energy consumption of graphite and fluorite production enterprises, as well as the energy consumption control of new construction, reconstruction and expansion projects.
