この概要は現在英語のみで提供しています。
適用範囲
This standard applies specifically to compressed air foam system fire fighting vehicles (CAFS fire trucks). It covers the terminology, technical requirements, testing methods, inspection rules, and marking for these specialized vehicles. It is mandatory for all manufacturers producing CAFS fire trucks for the Chinese market. The standard does not apply to other types of fire fighting vehicles, which are covered by different parts of the GB 7956 series.
技術要求
The standard specifies comprehensive technical requirements for the entire vehicle and its specialized systems. For the complete vehicle, it mandates that the fuel tank capacity must support driving 100 km followed by 2 hours of continuous operation at rated flow and pressure. The control panel must feature Chinese labeling, operational instructions, and a piping system diagram. For the compressed air foam system (CAFS), the standard requires the ability to project both dry and wet foam, with specific flow rate requirements for nozzles and monitors. The system must include automatic pressure balancing, residual pressure release, and automatic cleaning functions. The compressed air system must meet specific flow rate ratios relative to the foam solution flow and include safety valves that comply with JB/T 6441. The foam proportioning system must use corrosion-resistant materials and allow for adjustable mixing ratios with specific precision tolerances. Additional requirements cover the fire pump, fire monitor, piping systems, and liquid tanks. Manufacturers must ensure all piping is color-coded according to specific standards (e.g., black for compressed air, deep green for intake water). The standard also details requirements for instruments, equipment storage, warning lights, and accompanying documentation.
試験方法
The standard outlines rigorous testing procedures to verify compliance. Key tests include: Continuous operation testing of the fire pump under various pressure conditions; Foam projection performance testing to measure range, expansion ratio, and drainage time for both dry and wet foam; Dry foam adhesion testing on vertical surfaces; Reliability testing of the compressed air system and foam pump; Hydrostatic pressure testing for piping and tanks to ensure structural integrity; and Vacuum and priming time tests for the fire pump at maximum suction depth. All testing must be conducted under specified environmental conditions with corrections applied as needed.
よくある質問
What products are regulated under GB 7956.6-2015?
GB 7956.6-2015 regulates compressed air foam system fire fighting vehicles (CAFS fire trucks). It applies to the manufacturing, testing, and inspection of these specific vehicles.
Are there any mandatory requirements in GB 7956.6-2015?
Yes, Chapter 4 (Technical Requirements), Chapter 6 (Inspection Rules), and Section 7.1 (Marking) are mandatory. All other chapters are recommended.
What are the key performance tests for the compressed air foam system?
Key tests include power matching performance, projection stability, projection performance (range, expansion ratio, drainage time), and dry foam adhesion performance. The system must also pass reliability tests for the compressed air system and foam pump.
