APPENDIX B - GLOSSARY
Explosive gas atmosphere:
a mixture in air of combustible materials in the form of gas
vapour or mist in which, after ignition, combustion spreads
throughout the unconsumed mixture.
Lower explosive limit (LEL):
the volume of combustible gas or vapour in air below which
an explosive gas atmosphere will not be formed.
Exd:
flame proof or explosion proof within the confines of European
standards EN50014 and EN50018. An enclosure that can
withstand the pressure developed during the internal
explosion of an explosive mixture and which prevents
transmission of the explosion to the explosive atmosphere
surrounding the enclosure.
Exe:
increased safety within the confines of European standards
EN50014 and EN50019 applied to electrical apparatus that
does not produce arcs or sparks in normal service, in which
additional measures are applied so as to give increased
security against the possibility of excessive temperatures.
PPS:
polymer polyphenylene sulphide, suitable for use in most
chemical environments (eg acids, aldehydes, ketones,
alkalies, petroleum, aromatic hydrocarbons, alcohols, ethers,
esters and most chlorinated hydrocarbons). Avoid immersion
in solvents for extended periods. For further details contact
