Explosive atmospheres - Gas detectors. Performance requirements of open path detectors for flammable gases Ingestion-build-111333 Figure 1 – Product lifecycle1 Scope This part of EN 6007929 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. NOTE 1
