Explosive atmospheres – Part 29-4: Gas detectors – Performance requirements of open path detectors for flammable gases

Title (German)

Explosionsfähige Atmosphäre – Teil 29-4: Gasmessgeräte – Anforderungen an das Betriebsverhalten von Geräten mit offener Messstrecke für die Messung brennbarer Gase

Brief description

This standard specifies performance requirements of equipment for the detection and measuring of flammable gases or vapours in ambient air by measuring the spectral absorption by the gases or vapours over extended optical paths, ranging typically from one metre to a few kilometres. Such equipment measures the integral concentration of the absorbing gas over the optical path in units such as LFL metre for flammable gases.
