Описание
Gives a method of measuring the maximum experimental safe gaps for gas or vapour-air mixtures under normal conditions of temperature and pressure to permit the selection of the appropriate group of flameproof enclosures. Values of the MESG (g0) min. the difference (g100) min., - (g0) min., the most dangerous concentration, and the test temperature are tabulated.
