1 Scope

GB 29450-2012 is the Chinese national standard on the norm of energy consumption per unit product of glass fibers, 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 31 December 2012 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 October 2013. 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 standard specifies the production of glass fiber yarn and glass ball of energy consumption per unit of product (referred to as energy consumption) technical requirements limit the statistical range And calculation methods and energy management measures. This standard applies to alkali or E-glass balls and manufacturers to produce E-glass tank furnace or crucible method, ECR glass, and alkali glass Energy consumption calculation fiber production enterprises, assessment, and control the energy consumption of new projects. This standard does not apply to high-strength fibers of glass, high silica glass fiber, a special alkali-resistant glass fibers, glass fiber manufacturer.
