Alcance y aplicabilidad

This standard applies to domestic gas instantaneous water heaters with a rated heat input not exceeding 70 kW, including models for hot water supply, heating, and dual-purpose applications. It covers various types such as flue-type (D), forced exhaust (Q), balanced flue (P), forced balanced flue (G), and outdoor type (W) water heaters, as well as condensing water heaters. This standard is mandatory for all manufacturers selling gas water heaters in the Chinese market. It does not apply to gas storage water heaters.

Requisitos técnicos

The standard specifies comprehensive requirements for materials, structural integrity, and performance. For materials, it mandates that components in contact with gas, combustion products, or water must be corrosion-resistant or treated for corrosion protection, and the use of asbestos is strictly prohibited. Structurally, it requires robust gas system airtightness, with specific limits on leakage rates for valves and connections. Manufacturers must ensure at least two independent shut-off valves are installed in the gas path to the main burner. The standard also details requirements for safety devices, including flame failure devices, incomplete combustion preventive devices, and anti-dry burn safety devices, which must automatically shut off gas supply under hazardous conditions. Performance requirements cover combustion characteristics, thermal efficiency (minimum 84% for non-condensing models), hot water production capacity, and surface temperature limits to ensure user safety. Special requirements for heating, dual-purpose, and condensing models are addressed in appendices, including higher efficiency thresholds for condensing units.

Métodos de ensayo

Testing methods include evaluating gas system airtightness under pressure, measuring heat input accuracy, and assessing combustion conditions under no-wind, windy, and spray conditions. The standard outlines procedures for testing safety device response times, such as flame failure valve closing times and incomplete combustion prevention activation. Durability tests require components like gas valves and ignition devices to withstand tens of thousands of cycles. Thermal efficiency and hot water performance are measured under specified gas and water pressure conditions. Additionally, electrical safety and electromagnetic compatibility (EMC) tests are mandated for models using AC power, referencing standards like GB 4706.1 and GB/T 17626 series.

Preguntas frecuentes

What products are regulated under GB 6932-2015?

GB 6932-2015 regulates domestic gas instantaneous water heaters with a rated heat input up to 70 kW, including hot water supply, heating, and dual-purpose models, as well as condensing variants. It excludes gas storage water heaters.

Are there any updates from the previous version of GB 6932?

Yes, GB 6932-2015 replaces GB 6932-2001. Key updates include modified structural and installation requirements for natural exhaust water heaters, the addition of incomplete combustion preventive devices for natural exhaust models, and new requirements for gas/air ratio control devices and condensing water heaters.

How does GB 6932-2015 address electrical safety?

For water heaters using AC power, the standard mandates compliance with electrical safety requirements detailed in Appendix C, referencing GB 4706.1-2005. This includes tests for leakage current, dielectric strength, and grounding measures. EMC requirements are specified in Appendix D, covering voltage dips, surges, and fast transient bursts.
