Escopo e aplicabilidade

This standard applies to all types of fire monitors, including fixed fire monitors and mobile fire monitors. It covers devices used for spraying water, foam, or dry powder, such as fire water monitors, fire foam monitors, and fire powder monitors. It is mandatory for all manufacturers producing fire monitors for the Chinese market. The standard replaces the previous version GB 19156-2003.

Requisitos técnicos

The standard specifies comprehensive performance requirements for fire monitors. Chapter 5 and Chapter 7 are mandatory, covering critical aspects such as appearance, materials, and operational performance. Manufacturers must ensure strict adherence to these mandatory clauses. It details the spray performance parameters for various types of monitors, including water, foam, dry powder, and pulse monitors. Key parameters include rated flow, working pressure, and range. For foam monitors, requirements for foam expansion ratio and drainage time are also specified. Additionally, the standard outlines requirements for hydraulic sealing and hydraulic strength to ensure structural integrity under pressure. High and low temperature performance is mandated to guarantee reliable operation in extreme environments. For remote-controlled fire monitors, specific criteria are set for control response time, wireless control distance, and power source performance, including waterproofing and continuous operation time. Remote-controlled units must include a manual override mechanism.

Métodos de ensaio

The testing methods include visual inspection and salt spray corrosion tests for material durability. Operational performance is evaluated through force measurements for rotation and spray conversion. Spray performance tests measure flow rate, range, and for foam monitors, the foam expansion ratio and drainage time using specialized collectors. Hydraulic sealing and strength tests are conducted by pressurizing the monitor to specified limits. Environmental tests follow GB/T 2423.1 and GB/T 2423.2 for low and high temperatures, respectively. Remote control features are tested for response time, control distance, and power source endurance.
