Escopo e aplicabilidade

GB 7956.7-2019 applies specifically to pumper fire fighting vehicles (fire trucks primarily equipped with a fire pump without extinguishing agent tanks, designed to utilize water sources directly for firefighting or water supply). It covers the technical requirements, test methods, inspection rules, and packaging for these specialized vehicles. This standard is mandatory for manufacturers producing pumper fire trucks for the Chinese market, including those configured with large-flow or long-distance water supply systems.

Requisitos técnicos

The standard mandates comprehensive performance criteria for both standard pumper trucks and those equipped with advanced water supply systems. Key areas include chassis fuel capacity requirements to ensure continuous operation after driving 100km, and strict operational parameters for the fire water system. Manufacturers must ensure the fire pump's power matching ratio does not exceed 60% for diesel engines. For vehicles with water supply systems, the standard specifies performance thresholds for remote and large-flow systems, detailing requirements for suction modules, booster modules, and hose-laying devices. It also sets operational limits for auxiliary equipment like self-walking mechanisms and on-board cranes, ensuring structural integrity and functional reliability during deployment. Additionally, the standard outlines detailed specifications for instrumentation, warning lights, and the mandatory equipment list (e.g., fire hoses, nozzles, wrenches) that must be carried on board. All equipped instruments and control panels must clearly display pressure, flow, and operational instructions to ensure safe usage during emergencies.

Métodos de ensaio

The standard outlines rigorous evaluation procedures, including continuous operation tests (6 hours for standard pumpers, 12 hours for water supply system pumpers) to monitor engine and hydraulic temperatures. It also mandates hydrostatic strength and sealing tests for pumps and piping, and maximum vacuum and suction depth tests to verify priming performance. Specialized tests for self-loading and self-walking mechanisms are required to validate deployment speed and obstacle negotiation.

Perguntas frequentes

What products are regulated under GB 7956.7-2019?

This standard specifically regulates pumper fire fighting vehicles, which are primarily equipped with a fire pump and do not carry extinguishing agent tanks. It also covers vehicles equipped with specialized large-flow, long-distance, or combined remote large-flow water supply systems.

Are the requirements in GB 7956.7-2019 mandatory?

Yes, Chapters 4 and 6 of this standard are mandatory, while the remaining chapters are recommended. Manufacturers must comply with the mandatory technical requirements and inspection rules to sell these vehicles in China.

How does GB 7956.7-2019 differ from general fire fighting vehicle standards?

It builds upon the general requirements of GB 7956.1-2014 but introduces specific criteria for pump configurations, continuous operation durations (e.g., 6h or 12h tests depending on the system), and specialized structural modules like self-walking mechanisms and self-loading systems unique to water supply configurations.
