This European Standard specifies performance requirements for Group I (as defined in EN 50054) portable, transportable and fixed apparatus for the detection and measurement of methane concentrations in mine air. The apparatus, or parts thereof, are intended for use in mines susceptible to firedamp and shall meet the general requirements and test methods specified in EN 50054. This European Standard is restricted to apparatus intended for the detection and measurement of volume ratios of methane in air from 0 % (v/v) up to 100 % (v/v). NOTE: Apparatus covered by this European Standard will normally be intended to operate in volume ratios greater than 5 % (v/v)
