Outlines one acceptable method of test for the measurement of the maximum experimental safe gaps (M.E.S.G.) for gas or vapour-air mixtures under normal conditions of temperature and pressure so as to permit the selection of the appropriate group of flameproof enclosures. Values of the M.E.S.G. (g0) min. the different (g100) min. - (g0) min, the most dangerous concentration and the test temperature are tabulated.
