ATEX is an acronym and is derived from “Atmosphère Explosible” (French for explosive atmosphere).
ATEX is the directive 94/9/EC dated 23 March 1994 concerning equipment and protective systems intended for use in potentially explosive atmospheres.
Explosive atmospheres are a constant hazard in the chemical and petrochemical industries because of the processing techniques used. These explosive atmospheres are caused by escaping gas, vapours and mist, for example.
