Compliance overview
Scope and applicability
This standard applies to the design, manufacturing, and testing of turbo-jet engine fire fighting vehicles (涡喷消防车). It covers specific technical requirements for these specialized vehicles, including their chassis modifications, hydraulic systems, and the turbo-jet fire extinguishing device itself. It is intended to be used in conjunction with GB 7956.1, which defines the general technical conditions for all fire fighting vehicles.
Technical requirements
The standard outlines comprehensive technical specifications across several subsystems. For the complete vehicle, it mandates specific safety features like anti-static ground straps and secure additional fuel tank installations. The chassis modification requirements must align with the relevant clauses in GB 7956.3-2014. For the turbo-jet fire extinguishing device, the standard sets critical operational parameters. It requires the device to have an independent fuel tank with a minimum capacity and specific safety clearances. The device must demonstrate stable operation at rated speed, with strict limits on rotation speed fluctuations and operational noise levels at the operator's position. The device must also feature a self-protection fire extinguishing system and a speed limiter. The hydraulic system requirements ensure reliability under continuous operation, specifying temperature limits for hydraulic oil after multiple lifting cycles and mandating pressure gauges and relief valves. Additionally, the standard defines performance metrics for the fire water system, requiring adequate mixing of extinguishing agents and specific spray ranges and wind speeds at designated distances. Outriggers are mandatory for vehicles with a thrust-weight ratio exceeding 0.08.
Testing methods
Testing procedures include visual inspections and physical measurements for structural and safety requirements. The turbo-jet device performance is evaluated through operational tests, measuring water mist spray range, wind speeds at various distances, and rotational angles. Hydraulic system tests involve continuous cycling to monitor oil temperature and component integrity. Compliance is verified through both factory and type tests, ensuring all critical parameters meet the specified limits.
FAQs
What products are regulated under GB 7956.11-2025?
This standard applies specifically to turbo-jet engine fire fighting vehicles. It must be used in conjunction with GB 7956.1, which covers the general technical conditions for all fire fighting vehicles.
What are the key performance requirements for the turbo-jet fire extinguishing device?
