コンプライアンス概要
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 to various types of high-expansion foam fire fighting vehicles and fire fighting vehicles equipped with medium-expansion foam generators. It must be used in conjunction with GB 7956.1, which specifies the general technical conditions for fire fighting vehicles. This part specifically outlines the special requirements for the complete vehicle and dedicated devices of high-expansion foam fire fighting vehicles.
技術要求
The standard specifies comprehensive technical requirements for high-expansion foam fire fighting vehicles. Marking requirements mandate that system operation diagrams, operating instructions, and warning signs must be clearly displayed at operation points and hazardous areas. For the fire hydraulic system, the standard details requirements for the foam proportioning system, including the use of corrosion-resistant materials, the necessity of flushing devices, and strict mixing ratio accuracy limits. The system must maintain sealing performance under maximum working pressure and flow without leakage. Regarding foam discharge devices, the standard sets performance parameters for wind-driven and hydraulically-driven high-expansion foam generators, as well as medium-expansion foam generators. Key parameters include working pressure, premix solution flow rate tolerance, foam expansion ratio, and 50% drainage time. Additional requirements cover instruments, equipment placement, and the mandatory provision of at least 3 sets of deep cold protective clothing. The standard also specifies the necessary accompanying documents, tools, and spare parts, including electrical schematics and maintenance manuals.
試験方法
Testing methods include basic tests conducted according to GB 7956.1, and specific checks for markings and warning signs. The fire hydraulic system is tested for sealing performance under maximum pressure and flow, mixing ratio accuracy, and foam pump reliability over a 4-hour continuous operation. Foam discharge devices are tested according to GB 20031 for performance parameters and water impact resistance. Visual inspections are conducted for instruments, equipment placement, and accompanying documents.
