T/SITA 128-2026 Product quality grading of commercial gas combustion appliances
Basic Information
Scope
This document applies to gas-fired appliances that use urban gas in accordance with GB/T 13611 as an energy source, with combustion air drawn from indoors and combustion products discharged directly or indirectly into the outdoors. Specifically, it includes the following types of appliances: a) Steam generators with a rated thermal load of no more than 80kW, a steam pressure of no more than 80kPa, and a designed normal water level with a water capacity of less than 30L; b) Steamers with a rated thermal load of no more than 80kW and a steam chamber pressure of no more than 1200Pa; c) Deep fryers with a rated thermal load of no more than 50kW and a chamber pressure of no more than 80kPa; d) Cooking stoves with a rated thermal load of no more than 50kW; e) Large-pot stoves with a rated thermal load of no more than 80kW; f) Flat-top stoves with a rated thermal load of no more than 50kW; g) Constant-pressure boilers with a rated thermal load of no more than 100kW; h) Rice cookers with a stewing capacity of 6L or more; i) Dishwashers with a rated thermal load of no more than 50kW; j) Stir-fry stoves with a rated thermal load of no more than 60kW; k) Barbecue grills with a rated thermal load of no more than 50kW; l) Hot plate stoves with a rated thermal load of no more than 35kW; m) Other commercial gas appliances with a rated thermal load of no more than 80kW; n) Combinations of the above products. Note 1: The thermal loads mentioned above refer to the thermal loads of individual combustion units. Note 2: This document only applies to single-phase power supplies with a rated voltage of no more than 250V. This document specifies the technical grading evaluation indicators, factory capacity grading evaluation indicators, scoring and calculation methods, and overall evaluation principles for the quality of commercial gas-fired appliances.
