THE PERFORMANCE OF SOME PORTABLE GAS DETECTORS WITH AVIATION FUEL VAPOURS AT ELEVATED TEMPERATURES

A method of testing portable flammable gas detectors at elevated temperatures is described and results are given for tests on five proprietary instruments with o at 65 C, and n-hexane vapour n-hexane t o at 25 C. 'Avtag', and 'Civgas ' vapours In general, the aetectors gave a low response to 'Avtag ' and 'Civgas ' vapours and there is evidence that the readings are changed significantly with increase of ambient temperature. for the low response are given. Possible reasons KEY WORIS: Explosimeter, detector, flammable vapour, aircraft fuels. Crown copyright This repor-t has not been pubh shed and should be considered as contioanticl odvonce information.
