Champ d’application

This standard specifies the protection performance requirements and testing methods for fire electronic products used in various environments. It applies to fire alarm systems, controllers, and detectors installed in both indoor and outdoor settings, including normal and special use environments. It is mandatory for all manufacturers producing fire electronic products for the Chinese market. It officially replaces the previous GB 23757-2009 edition.

Exigences techniques

The standard categorizes operating conditions into normal use environments and special use environments. Normal environments cover specific temperature, humidity, and electromagnetic conditions, while special environments address extreme temperatures, condensation, pollution, microbial erosion, and explosion hazards. Structural requirements mandate that materials must withstand mechanical, electrical, and thermal stresses. It specifies enclosure protection ratings (IP codes) based on installation locations (indoor, outdoor, ground-mounted). Manufacturers must ensure proper terminal configurations and protective grounding for safety. Fire hazard tests, such as the glow wire test and needle flame test, are required for material heat resistance. Performance requirements include strict limits on temperature rise for internal components and minimum clearances for creepage distances and electrical clearances. The standard also outlines comprehensive electromagnetic compatibility (EMC) requirements to ensure operational stability under various electromagnetic phenomena. For products with backup power, specific regulations apply to batteries and备用电源. Certain lithium batteries are prohibited, and temperature monitoring with automatic cutoff is mandatory. Additional safety features like carbon monoxide or hydrogen detection may be required depending on battery type and capacity.

Méthodes d’essai

The standard outlines a series of rigorous testing procedures to verify compliance. Key tests include the glow wire test and needle flame test for fire hazard assessment, and enclosure protection (IP code) tests for environmental ingress. For ground-mounted products, surface wear resistance and impact resistance tests are mandatory. Additionally, it specifies procedures for terminal mechanical strength, climate and mechanical environment tests, temperature rise tests, and comprehensive EMC testing in accordance with referenced standards like the GB/T 17626 series.

Questions fréquentes

What products are regulated under GB 23757-2025?

It applies to all fire electronic products, including controllers and detectors, used in various indoor and outdoor environments within China.

Are there any updates from the previous version of GB 23757?
