The issuing of the previous versions. ---First issued in 2014 as GB 30720-2014 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Domestic Gas Cooking Appliances; ---This is the first revision, which incorporates the content of GB 30531-2014 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Commercial Gas Cooking Appliances. Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Gas Cooking Appliances1 Scope
This document specifies the energy efficiency grades, technical requirements and test methods for gas cooking appliances. This document is applicable to domestic gas stoves and integrated stoves with a rated heat load of not greater than 5.23 kw using town gas (hereinafter collectively referred to as “domestic gas cooking appliances”), and is also applicable to cooking stoves with a rated heat load of not greater than 60 kw, large pot stoves with a rated heat load of not greater than 80 kw, water-tank type and steam-generating type steam boxes and steam generators with a rated heat load of not greater than 80 kw (hereinafter collectively referred to as “commercial gas cooking appliances”). This document does not apply to gas cooking appliances used in means of transportation. NOTE. the rated heat load of domestic gas stoves and integrated stoves refers to the heat load of a single combustor; the rated heat load of cooking stoves, large pot stoves, steam boxes and steam generators refers to the heat load of a single combustion unit.2 Normative References
