Scope

This European Standard is applicable to fixed gas detection systems for the detection and measurement of flammable or toxic1 gases or vapours or oxygen. This European Standard supplements the requirements of the European Standards for electrical apparatus for the detection and measurement of flammable gases, vapours ( e.g. EN 61779 or EN 50241), toxic gases (e.g. EN 45544) or oxygen (e.g. EN 50104). Applying the above mentioned metrological standards ensure the measuring performance in normal operation of the gas detection system. Additionally the requirements of this European Standard address the functional safety of gas detection systems and encompasses c
