Scope

本文件规定了在正常温度和压力条件下（20 ℃，101.3 kPa）测定气体/空气混合物或蒸气/空气混合物最大试验安全间隙(MESG)的试验方法和分类原则，为气体和蒸气分类提供指南。本文件同时给出了常见的可燃性气体和蒸气的特征参数，以便选择适当的设备类别。本文件还规定了在大气压下测定蒸气/空气或气体/空气混合物自燃温度（AIT）的试验方法，以便选择适当的设备温度组别。提供的物质的化学特性值有助于选择危险场所适用设备。当可获得验证试验结果时，可进一步添加数据。
附录B的表B.1中包含的物质特性的选择特别考虑了设备在危险场所的使用情况。
本文件的数据来源于参考文献中列出的一些参考资料。
测定MESG或AIT的这些方法也可用于气体/空气/惰性气体混合物或蒸气/空气/惰性气体混合物。但是，关于空气/惰性气体混合物的数据未列出。
