Electrical apparatus for the detection and measurement of combustible gases - General requirements and test methods
This European Standard specifies general requirements for construction and testing and describes the test methods that apply to portable, transportable and fixed apparatus for the detection and measurement of combustible gas or vapour concentrations with air. The apparatus, or parts thereof, is intended for use in potentially explosive atmospheres and in mines susceptible to firedamp. This European standard is supplemented by the following European Standards, concerning the specific requirements for performance of the various types of apparatus:EN 50055: Performance requirements for Group I apparatus indicating up to 5 % (v/v) methane in air; EN 50056: Performance requirements for Group I apparatus indicating up to 100 % (v/v) methane EN 50057: Performance requirements for Group II apparatus indicating up to 100 % lower explosive limit; EN 50058: Performance requirements for Group II apparatus indicating up to 100 % (v/v) gas- NOTE 1: Group I apparatus indicating up to 100 % (v/v) methane and Group II apparatus indicating up to 100 % (v/v) gas are suitable for use only with the specific gases for which they have been calibrated. NOTE 2: For the purposes of this European Standard the term 'combustible gas' includes combustible vapours but excludes mist and dust, see 3.3 note 1. This European Standard is applicable to combustible gas detection apparatus intended to provide an indication) alarm and/or other output function, the purpose of which is to give a warning of potential explosion hazard and in some cases to initiate automatic or manual protective actions. This European Standard is applicable to apparatus, including the integral sampling systems of aspirated apparatus intended to be used for commercial and industrial safety applications. This European Standard does not apply to external sampling systems, or to apparatus of the laboratory or scientific types, or to apparatus used only for process control purposes
