Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to the design, manufacturing, and inspection of fire emergency lighting and evacuate indicating systems used in industrial and civil buildings. It covers system equipment including fire emergency luminaires, central control panels, centralized power supplies, and distribution boxes. It is mandatory for all manufacturers producing fire safety equipment for the Chinese market.

Exigences techniques

The standard specifies comprehensive functional and performance requirements for system components. For fire emergency luminaires, it dictates strict rules on emergency activation times, battery discharge durations, and luminous flux requirements. Manufacturers must ensure luminaires meet specific illumination and power conversion criteria. For central control panels and centralized power supplies, the standard outlines requirements for automatic and manual emergency start functions, fault alarm mechanisms, and system self-inspection protocols. These devices must maintain operational continuity during main power failures. The standard also details general technical requirements concerning device structure, creepage distances, and material flammability ratings (referencing GB/T 5169). Equipment must be constructed with appropriate protective enclosures and electrical insulation to ensure safety during emergency operations.

Méthodes d’essai

GB 17945-2024 mandates a rigorous suite of tests to verify compliance. Key procedures include basic functional tests, repeated conversion tests, and voltage fluctuation tests. Devices must undergo these evaluations to prove operational reliability. Environmental endurance is assessed through high and low temperature operation tests, constant damp heat tests, and vibration tests. Equipment must maintain normal operation during and after these environmental stressors. Electromagnetic compatibility (EMC) is verified through a series of immunity tests, including electrostatic discharge, electrical fast transient/burst, and surge immunity tests (referencing GB/T 17626 series). Systems must resist specified levels of electromagnetic interference without functional failure.

Questions fréquentes

What products are regulated under GB 17945-2024?

GB 17945-2024 applies to fire emergency lighting luminaires, exit signs, central control panels, centralized power supplies, and distribution boxes used in industrial and civil buildings. It is mandatory for the design, manufacturing, and inspection of these systems.

Are there any major updates from the previous GB 17945-2010 version?

The 2024 version introduces new classifications for Type A and Type B devices based on voltage ratings, adds requirements for multi-information composite signs and personnel positioning functions, and updates EMC and environmental endurance testing criteria. Manufacturers must update their product designs to meet these new structural and performance requirements.

How does GB 17945-2024 differ from ISO standards?

While GB 17945-2024 references some international electromagnetic compatibility standards (like IEC 61000-4 series equivalents), it is a distinct Chinese national standard with specific national requirements for fire safety systems, including unique evacuation sign graphics and mandatory system self-inspection protocols.
