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.
