Compliance-Überblick

Dieser Überblick ist derzeit nur auf Englisch verfügbar.

Geltungsbereich und Anwendbarkeit

This standard applies to the design, manufacturing, and inspection of pyrolysis sensing electrical fire monitoring detectors used in electrical fire monitoring systems. It is mandatory for all manufacturers producing these specific detectors for the Chinese market. It covers both independent and non-independent detectors, including multi-sensor combined detectors.

Technische Anforderungen

The standard specifies comprehensive requirements for pyrolysis sensing detectors, including general appearance, basic functions, and monitoring alarm capabilities. Detectors must not have the function of breaking distribution circuits. It also defines strict communication protocols for non-independent detectors. It outlines performance criteria for key components such as indicator lights, displays, and terminal blocks. The electrical strength and insulation resistance requirements ensure safety under specified voltage conditions. Manufacturers must ensure detectors meet these component-level specifications. The standard mandates strict electromagnetic compatibility (EMC) and environmental endurance criteria, covering voltage fluctuations, mechanical vibrations, low temperatures, constant damp heat, and dust resistance. These requirements align with referenced standards like the GB/T 17626 series for EMC.

Prüfverfahren

Testing includes basic function, communication, and monitoring alarm tests. The core pyrolysis alarm performance test utilizes specific materials like PVC, ABS, and FR-4 epoxy resin to simulate thermal decomposition. Detectors must trigger an alarm within 13 minutes during this test. Additional tests cover electrical safety (insulation, leakage current, electrical strength), EMC immunity (ESD, surges, radiated fields), and environmental durability (vibration, collision, low temperature, damp heat, dust) in accordance with GB/T 16838.

Häufige Fragen

What products are regulated under GB 14287.5-2025?

It regulates pyrolysis sensing electrical fire monitoring detectors, including both independent and non-independent types used in electrical fire monitoring systems.

When will GB 14287.5-2025 be implemented?

The standard was issued on October 31, 2025, and will be officially implemented on November 1, 2026. Manufacturers must ensure compliance before this date.

What materials are used for the pyrolysis alarm performance test?

The test uses specific thermal decomposition sheets made of PVC, ABS, and FR-4 epoxy resin to evaluate the detector's response time.
