GB 30530-2024Norm of energy consumption per unit production of dimethyl siloxane (English PDF)

1 Scope

GB 30530-2024 is the Chinese national standard on norm of energy consumption per unit production of dimethyl siloxane, 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 29 April 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2025. 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 grade, technical requirements, statistical scope and calculation method of the allowance of comprehensive energy consumption per unit production (referred to as energy consumption) of dimethyl siloxane. This document is applicable to the calculation and assessment of the comprehensive energy consumption per unit production of dimethyl siloxane, as well as the energy consumption control of new (renovation, expansion) projects.
