Standard for Gas and Vapour Detectors and Sensor, Including Accessories

This Standard covers requirements for toxic and combustible gas and vapour detectors and sensors, and accessories, including mechanical guards intended to be portable or employed in indoor or outdoor locations.

A detector and/or sensor , as covered by these requirements, consists of an assembly of electrical components coupled with a sensing means inside a chamber, or by separate components to detect toxic and/or combustible gases or vapours. The detector includes provision for the connection to a source of power and signaling circuits and optional remote control circuits. Additional functionality, such as a heat detector, heat sensor, smoke detector, smoke sensor, or audible signaling appliance/device, is permitted to be incorporated as part of the toxic combustible gas and vapour detector assembly and are to be evaluated to the applicable standard(s).
