Compliance overview
Scope and applicability
This standard applies specifically to the design, manufacturing, and inspection of water mist fire fighting vehicles (水雾消防车). It covers the complete vehicle requirements and the specialized water mist extinguishing devices equipped on the truck. This standard is mandatory for all manufacturers producing water mist fire trucks for the Chinese market, and it must be used in conjunction with the general technical requirements specified in GB 7956.1.
Technical requirements
The standard outlines comprehensive technical specifications across several critical areas. For the complete vehicle, it mandates specific requirements depending on the drive mechanism of the water mist device, such as fueling protocols for independent engines, power capacity for electric drives, and specific IP67 protection and battery temperature monitoring for electric vehicle chassis. Manufacturers must ensure all automatic control mechanisms include manual emergency overrides. For the water mist extinguishing device, the standard sets strict criteria for pump sets (including insulation resistance and startup time), gas cylinder drives (requiring shock absorption and pressure relief valves), and hose reels. The tank design must adhere to volume error limits, incorporate anti-corrosion treatments, and feature adequate manholes, overflow pipes, and filtration systems. Additionally, the standard defines critical performance metrics for the extinguishing system. This includes parameters for spray performance, water curtain functionality, low liquid level protection, sealing performance, and overpressure protection. The device must demonstrate reliable operation under continuous rated conditions for 1 hour without failure.
Testing methods
The standard specifies a series of evaluations to verify compliance. Visual inspections and operational checks are used to validate control labels, warning signs, and manual emergency functions. Performance testing includes measuring pressure, flow rate, and spray range under specific environmental conditions, as well as evaluating fire extinguishing capabilities for Class A and B fires. Reliability and safety are assessed through hydrostatic strength tests, sealing performance tests, and continuous operation tests. Additionally, specific electrical safety tests, such as insulation resistance and dielectric strength, are mandated for motor-driven pump sets, alongside battery depletion and temperature monitoring tests for electric chassis.
FAQs
What products are regulated under GB 7956.9-2025?
This standard regulates water mist fire fighting vehicles. It specifies the technical requirements, testing methods, and inspection rules for the complete vehicle and its specialized water mist extinguishing devices, including pump-driven, gas cylinder-driven, and electric chassis-driven configurations.
How does GB 7956.9-2025 relate to other fire fighting vehicle standards?
It is the Part 9 of the GB 7956 series. It specifically focuses on the unique technical requirements and专用装置 (specialized devices) of water mist fire fighting vehicles, and must be used in conjunction with GB 7956.1 which covers the general technical conditions for all fire fighting vehicles.
Are there specific requirements for electric vehicle chassis in this standard?
The standard introduces specific requirements for electric vehicle chassis, such as limiting the water tank capacity to 1000L and requiring IP67 protection for the power extraction port. It also mandates battery temperature monitoring with automatic power cutoff upon overheating, and requires a minimum 20% remaining battery capacity after 1 hour of continuous spraying.
