Explosion proof designation in use of US 1

[kimseunghee]

The explosion proof equipment is normally designated as protection type such as EXe Exd or so on. How do I know protection type from designation from US vendor. The only thing I obtain from vendor site is to give the kind of Class and Div. The designation does not identify protection type in US ? How can compare protection type(stipulated in IEC) with US designation ?

In USA NEC and in Canada CSA defines explosion proof as Class I, Division 1 and 2 Groups A, B, C, D, E, F and G. Factory Mutual has a nice table listing also the international partners.
