标准摘要
[中文适用范围]： 给出了在正常温度和压力条件下测量气体或蒸气-空气混合物的最大实验安全间隙的方法，以便选择适当的隔爆外壳组。 MESG 值 (g0) 最小值差值 (g100) 最小值、- (g0) 最小值、最危险浓度和测试温度均以表格形式列出。 [外文原描述]： 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.
