Electrical apparatus for the detection and measurement of oxygen - Performance requirements and test methods
This European Standard specifies performance requirements and test methods for portable, transportable and fixed electrical apparatus for the measurement of the oxygen concentration in gas mixtures indicating up to 25 % (v/v). This European Standard applies to apparatus intended for commercial and industrial safety applications, including integral sampling systems of aspirated apparatus. In the case of inert gas purging, this European Standard applies also to apparatus with an oxygen measuring function for explosion protection. It does not apply to external sampling systems, nor laboratory, scientific or medical equipment nor those which are used exclusively for process control. NOTE: The most commonly used oxygen sensors in commercial equipment for industrial application are: paramagnetic sensors; electrochemical sensors (aqueous and solid electrolytes)
