GB 21340-2019The norm of energy consumption per unit products for glass products and cast stone (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed and managed by the China National Standardization Administration. This standard replaces GB 21340-2013 "flat glass unit energy consumption limit", GB 30252-2013 "photovoltaic rolled glass Energy consumption limit per unit product, GB 29451-2012 "Energy consumption limit for cast stone unit products". With GB 21340-2013, Compared with GB 30252-2013 and GB 29451-2012, except for editorial changes, the main technical changes are as follows:

--- Added the definition of "special production line for flat glass for automobiles" (see 3.2);

--- Supplemented the energy consumption correction factor of the flat glass unit product of the special flat glass production line for automobiles (see Table 2 in 4.1);

--- Supplemented the energy consumption limit level (see 4.1);

--- Removed the heat consumption index of the flat glass unit melting furnace (see Chapter 4 of GB 21340-2013);

--- Increased the comprehensive energy consumption access value of flat glass unit products (see 5.2,

4.2 in GB 21340-2013);

--- Removed the advanced value of the energy consumption limit of flat glass unit products (see

4.3 in GB 21340-2013), photovoltaic calendered glass unit production The advanced value of energy consumption (see

4.3 in GB 30252-2013) and the advanced value of comprehensive energy consumption of cast stone unit products (see GB 29451- In.2012, 4.3);

--- Removed energy management and measures (see Chapter 6 of GB 21340-2013, Chapter 6 of GB 30252-2013 and Chapter 6 of GB 29451-2012). This standard was drafted.

1 Scope

GB 21340-2019 is the Chinese national standard on the norm of energy consumption per unit products for glass products and cast stone, 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 14 October 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2020. 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 energy consumption per unit of flat glass, tempered glass, photovoltaic rolled glass and cast stone (hereinafter referred to as "energy consumption") Language and definition, energy consumption limit level, technical requirements, energy consumption correction factor, statistical range and calculation method. This standard is applicable to the production of transparent and bulk-colored sodium-calcium-silicate flat glass products by float process, and steel produced by horizontal tempering method. Glass products, photovoltaic rolled glass products produced by calendering, and enterprises producing cast stone products for energy consumption calculation, assessment and new construction And energy control of the expansion and expansion project. This standard does not apply to the production of ordinary embossed glass, wired glass and special flat glass for the production of aerospace, electronics, information and other industries. Glass products are also not suitable for the production of automotive tempered glass, chemically tempered glass and non-horizontal tempering methods for the production of tempered glass products.
