Aperçu de conformité

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

Champ d’application

This standard applies to temperature sensing electrical fire monitoring detectors used in electrical fire monitoring systems. It is mandatory for manufacturers producing these specific fire safety devices for the Chinese market. The scope includes independent and non-independent detectors, as well as contact and non-contact types, but excludes residual current detectors covered under GB 14287.2.

Exigences techniques

The standard specifies mandatory requirements for basic performance, including alarm response times and temperature setting ranges. Detectors must issue an alarm within 40 seconds when the monitored temperature reaches the set value. It also defines monitoring alarm functions, requiring distinct audible and visual signals with specific sound pressure levels. Furthermore, the standard outlines stringent electromagnetic compatibility (EMC) and environmental tolerance criteria, ensuring reliable operation under various electrical and climatic conditions as per GB 16838.

Méthodes d’essai

Testing procedures evaluate the detector's basic performance and alarm functionality under controlled temperature changes. Manufacturers must verify compliance through a series of rigorous electrical and environmental tests. Key tests include insulation resistance, electrical strength, and various EMC immunity tests referencing the GB/T 17626 series. Additionally, climatic and mechanical tests such as low temperature operation and constant damp heat are required.
