Although # 4 answer is on right track. But apart from area
classification, mech grip is also equally imp. to Sum up:
Ex'e'(single compression) equal to IP54.(IEC 60079-0,7)
Ex'd' (double compression) equivalent IP66. (IEC 60079-1).
Double is better always... but may not be necessary for all
applications.
