NettetIt can clearly be seen that 50% LEL of methane in EN60079 calculates to a 2.2% volume concentration in air, as oppose to 2.5% volume as stated in ISO10156. Therefore if a detector is calibrated according to EN60079 using a mixture of 50% LEL methane made to ISO 10156, a 13.6% error would occur potentially invalidating the calibration. fx6065 flightNettet20. sep. 2024 · The lower explosive limit (LEL) is the minimum concentration of a specific combustible gas required to fire combustion when in contact with … fxap5c7776plwf15041nwvt6fjaLower flammability limit Lower flammability limit (LFL): The lowest concentration (percentage) of a gas or a vapor in air capable of producing a flash of fire in the presence of an ignition source (arc, flame, heat).
