Escopo e aplicabilidade

This standard applies to remote-controlled fire foam (water) monitor systems, which are fixed fire extinguishing devices capable of long-distance operation. It covers systems driven by hydraulic, pneumatic, or electric control mechanisms, including components like fire monitors, monitor towers, power sources, and foam proportioning devices. It is specifically designed for remote-controlled systems and does not apply to manually operated fire monitors.

Requisitos técnicos

The standard specifies comprehensive performance parameters for various system components, including flow rate tolerance, rated working pressure, and range for foam, water, and combination monitors. It mandates strict material and structural criteria, requiring components to be manufactured from corrosion-resistant materials or treated for corrosion protection, with marine equipment requiring specific seawater corrosion resistance. Critical components must withstand rigorous hydrostatic strength and sealing tests without leakage or permanent deformation. Furthermore, the standard outlines specific operational parameters, requiring the system to start reliably with a response time of less than 5 seconds and maintain continuous operation for at least 3 hours. For systems used in hazardous locations, the explosion-proof performance of electrical components must comply with relevant GB 3836 standards.

Métodos de ensaio

Testing procedures include visual inspections, hydrostatic strength tests (at 1.5 times maximum working pressure), and hydrostatic sealing tests (at 1.1 times maximum working pressure). It also mandates salt spray corrosion tests lasting 72 hours to evaluate material durability, alongside operational performance tests measuring flow rates, range, and system response times. Electrical and explosion-proof characteristics are verified according to GB/T 14048.1 and GB 3836 series standards.

Perguntas frequentes

What products are regulated under GB 19157-2003?

The standard regulates remote-controlled fire monitor systems, which include liquid-controlled, air-controlled, and electric-controlled fire monitors, along with associated power sources, control devices, fire monitor towers, and foam proportioning devices.

Are there any mandatory clauses in GB 19157-2003?

Yes, specific clauses regarding performance parameters and critical performance requirements (such as structural integrity, pressure resistance, and system response time) are mandatory for compliance.

How does GB 19157-2003 relate to ISO standards?

The standard references several international equivalents, such as ISO 4413 for hydraulic systems and IEC 60079 for electrical equipment in explosive atmospheres, aligning its testing and safety protocols with international practices.
