GB 35848-2024Commercial gas-burning appliances (English PDF)

1 Scope

China's mandatory standard for commercial gas-burning appliances - the ranges, wok burners, ovens, fryers, steamers, griddles and boiling pans of restaurant and canteen kitchens. They differ from domestic appliances in ways that matter for safety rather than for cooking: the heat inputs are several times larger, the appliances run for many hours a day, they stand in a room with a mechanical extraction system that can pull enough air to disturb the combustion, and they are operated by staff who change often and are not the owner. It specifies the terms and definitions, the classification, the requirements, the test methods, the inspection rules and the marking, packaging, transport and storage of commercial gas-burning appliances, and it applies to the appliances fired by town gas, natural gas or liquefied petroleum gas used in commercial catering. The requirements cover the gas circuit with its connections, taps and governors; the burners and their stability across the range of gases and pressures the appliance may see; the flame supervision device, which on a commercial appliance is the single most important safety component, because a burner that goes out unnoticed in a busy kitchen fills the room; the ignition; the combustion products, with the carbon monoxide limits that decide whether the kitchen is habitable; the thermal efficiency; the surface temperatures and the guarding of a machine that people work around all day; the electrical safety of the powered appliances; and the stability and mechanical strength. The whole appliance must also satisfy the general safety requirements for gas burning appliances of GB 16914. Issued on 29 April 2024 and in force since 1 August 2024, it replaces GB 35848-2018.
