Champ d’application

This standard applies to domestic dimethyl ether gas cooking appliances with a rated heat input of a single burner not exceeding 5.23kW, utilizing dimethyl ether specified in GB 25035. It is not applicable to gas stoves used in moving transport vehicles or gas-electric hybrid stoves. Manufacturers must ensure their cooking appliances meet these specific criteria for the Chinese market.

Exigences techniques

The standard specifies stringent structural requirements for the appliances, including stability, tilt resistance, and the mandatory inclusion of a flame failure protection device. Each burner must be equipped with at least two independent gas valves to ensure safety. Specific structural guidelines are also provided for built-in stoves, emphasizing anti-corrosion and thermal deformation limits. Material requirements mandate that components in contact with dimethyl ether must be compatible with its characteristics. Key components like burner ports, nozzles, and gas ducts must meet specific melting point thresholds (e.g., >700°C for burner ports). Sealing materials and lubricants must undergo strict resistance testing against dimethyl ether. Performance criteria cover gas tightness, heat input accuracy, and combustion conditions, including limits on carbon monoxide concentration and noise levels. The standard also sets requirements for thermal efficiency, electrical safety for AC-powered ignition devices, and durability of critical components like valves and ignition devices. Appliances must pass endurance, vibration, and drop tests to ensure long-term reliability.

Méthodes d’essai

Testing methods are primarily conducted in accordance with GB 16410-2007 and GB/T 16411-2008. Key evaluations include gas tightness testing under specific pressures, combustion condition assessments to measure flame stability and CO emissions, and thermal efficiency tests. Additionally, the standard outlines procedures for endurance testing of safety devices and physical stress tests like vibration and drop tests for packaging.
