« Back to Glossary Index

Code used to identify “flameproof” to IEC 60079-1. Similarly, EEx d to EN50 018, andAEx d to FM 3600 (also to ISA 12.22.01 & 12.00.01). Originally a British term describing a device enclosed in a housing that is capable of withstanding an explosion of a specified gas or vapor that may occur within it while preventing the propagation of flame to a surrounding flammable atmosphere, and operating at such an external temperature that a surrounding flammable atmosphere will not be ignited thereby. The design of such a device includes consideration of pressure wave propogation and pressure piling within the enclosure. May be used in Zone 1 and Zone 2. Roughly equivalent to, but not directly interchangeable with, the term “explosionproof” as used in North America.
