Scope

Main technical content: This document specifies the terms and definitions, basic requirements, evaluation index system, and evaluation methods for the evaluation of candidate products of "co-generation excellent products" for household gas stoves. This document applies to household gas stoves (excluding integrated stoves) with a rated heat load of ≤5.23kW using only urban gas, and household gas-electric dual-use stoves with a rated heat load of ≤5.23kW using urban gas and a total rated input power of ≤5.00kW using electricity. This document does not apply to gas stoves used in mobile transportation vehicles. The evaluation indicators for "co-generation excellent products" of household gas stoves are mainly divided into two categories: mandatory performance indicators and optional performance indicators. Mandatory performance indicators include: gas tightness, surface temperature rise (dry battery shell, hose joints, valve shell, igniter shell, parts that must be touched by hands during operation), electric ignition device, heat load deviation, thermal efficiency, CO content in flue gas (theoretical air coefficient α=1), flameout protection device (valve opening time, valve closing time), and nitrogen oxide emission level. Optional performance indicators include: flame stability, wind resistance, anti-dry-burn protection function, smoke-stove linkage function, and timed shutdown function.
