Synthetic leather unit product energy consumption limit

1 Scope

GB 36887-2018 is the Chinese national standard on the norm of energy consumption per unit product of synthetic leather, 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 19 November 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 December 2019. Classification: ICS 27.01, 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 standard specifies the production of N,N-dimethylformamide (hereinafter referred to as DMF) for the production of synthetic leather and synthetic leather. Terms and definitions, classifications, energy consumption limit levels, technical requirements, statistical ranges and calculation methods for energy consumption (hereinafter referred to as energy consumption) limits. This standard applies to synthetic leather production and DMF recovery energy consumption calculation, management and assessment of synthetic leather production enterprises, as well as new or modified Energy control for expansion projects.
