T/CNHA 1020-2019 Integrated stove-hood

Scope

Scope: This standard specifies the terms and definitions, product classification, requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of integrated stoves. This standard applies to integrated stoves using urban gases other than dimethyl ether, biogas, and liquefied petroleum gas mixed with air, with a single-phase rated voltage of ≤250V, including: a) Integrated stoves with a rated heat load of ≤5.23 kW per burner; b) Integrated stoves with a rated heat load meeting the requirements of a) and a total rated electrical input power of ≤5.00 kW, equipped with electrical units. Integrated stoves using dimethyl ether, biogas, liquefied petroleum gas mixed with air, and gas types other than those specified in GB/T 13611 may refer to this standard for use. This standard does not apply to integrated stoves used in moving vehicles or integrated stoves with internal circulation smoke extraction devices. This standard does not consider: — The use of the appliance by children; — People with physical, sensory, or mental disabilities. Main technical content: On the basis of GB/T 17713-2011, the standard raises the requirements for indicators such as aerodynamic performance, noise, odor reduction, and grease separation; on the basis of GB/T 16410-2007, it raises or refines the requirements for combustion noise, flameout noise, nitrogen oxide concentration in dry flue gas, flame transfer, flame extinction, backfire, black smoke, contact yellow flame, combustion stability of small fire burners, combustion stability when using oversized pots, temperature rise of valve housings and igniter housings, thermal shock resistance, and gravity shock resistance; it adds requirements for flue gas fire safety devices, check valves, and electromagnetic compatibility, and, in accordance with GB 30720-2014, it sets requirements for the thermal efficiency of integrated stoves at the level of Class 2 energy efficiency.
