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.
