Visão geral de conformidade

Esta visão geral está disponível por enquanto apenas em inglês.

Escopo e aplicabilidade

This standard applies to cabinet heptafluoropropane gas fire extinguishing equipment and cabinet carbon dioxide gas fire extinguishing equipment stored in high-pressure form. It is not applicable to cabinet carbon dioxide gas fire extinguishing equipment stored in low-pressure form. Manufacturers of fire protection systems for industrial and commercial facilities must ensure their products comply with these mandatory requirements.

Requisitos técnicos

The standard specifies comprehensive requirements for the composition, performance, and safety of cabinet gas fire extinguishing equipment. Key technical parameters include working temperature ranges, storage pressure, and maximum filling density. The equipment must support automatic, manual, and optionally mechanical emergency startup modes. Manufacturers must ensure the equipment features clear warning signs and reliable linkage performance. It also details requirements for critical components such as cylinder assemblies, container valves, safety relief devices, and low-leakage high-seal valves. Furthermore, the standard introduces new requirements for concentration distribution performance and a status monitoring and data application platform.

Métodos de ensaio

The standard outlines a rigorous testing protocol to verify compliance. Key evaluations include hydraulic strength tests, air tightness tests, and vibration tests to ensure structural integrity. Engineers must conduct concentration distribution tests to confirm the equipment can extinguish open flames within 30 seconds after discharge. Additional assessments cover corrosion resistance (salt spray, stress, sulfur dioxide), temperature cycling leakage, and impact resistance for accidental discharge protection devices. Performance tests for pressure displays, weighing devices, and signal feedback devices are also mandated.
