1604 is obsolete

UL 1604 is obsolete and has been superceded by ANSI/ISA 12.12.01.  The end of life date for 1604 was July 31, 2012.  That being said, this is a good overview of the requirements for either standard.  Anyone working with this type of product should also get familiar with the IEC 60079 series standards.  They define the hazardous locations (known as explosive atmospheres or ATEX) requirements for europe.  IEC60079-0 describes the basic requirements, and the others describe varios protection methods.

Thanks for the primer, Jane. We don't hear much about UL 1604, but it sounds like a rating that more engineers -- mechanical and electrical -- should be familiar with.
