Alcance y aplicabilidad

This standard applies to fire electronic products used in installation sites within general industrial and civil buildings. It covers the protection requirements for enclosures, materials, and terminals of fire safety equipment like controllers and alarms. Products installed in special environments with specific performance criteria may also fall under its scope unless otherwise specified by other relevant standards. Manufacturers must ensure their products meet the mandatory requirements of Chapter 3 to enter the Chinese market.

Requisitos técnicos

The standard specifies stringent criteria for enclosures, requiring the use of non-combustible or flame-retardant materials. Indoor controller-type products must meet a minimum protection rating of IP30, while outdoor equipment must feature dust and water resistance. Floor-mounted products require water resistance and wear resistance, and surface panels of floor-mounted fire emergency luminaires must possess impact resistance. For insulating materials, the standard dictates heat resistance limits based on glow wire flammability tests, with specific temperature thresholds for components securing current-carrying parts versus other parts. Main circuit wiring must utilize flame-retardant wires with an operating temperature parameter exceeding 105°C. Terminal blocks and specific insulating components must pass the needle flame test. The standard also outlines structural and marking requirements for terminals to ensure good electrical contact and sufficient mechanical strength. Additionally, protective grounding must be provided for exposed conductive parts that pose a risk, with terminals required to be easily accessible, corrosion-protected, and clearly marked. All products must pass the corresponding tests detailed in Chapter 4 before market approval.

Métodos de ensayo

The standard details a series of rigorous testing procedures to verify compliance. These include enclosure protection rating tests (referencing GB 4208), sand and dust tests, and rain tests. Mechanical and environmental durability are assessed through surface wear resistance tests (using a Taber-type abrasion machine) and impact tests (via steel ball free-fall). Fire hazard risks are evaluated using glow wire flammability tests and needle flame tests, while the mechanical strength of terminals is verified through specific tightening torque tests.

Preguntas frecuentes

What products are regulated under GB 23757-2009?
