ISA-RP12.4-1996: Pressurized Enclosures

This recommended practice provides guidance to those who design and install pressurized systems for hazardous (classified) locations, and should be used in conjunction with ANSI/NFPA 496, Purged and Pressurized enclosures for enclosures for electrical equipment. It also provides performance and test recommendations so that the enclosure and components mounted internally or protruding through the enclosure are unlikely to cause ignition of a surrounding flammable atmosphere.
