Explosion-proof markings under ATEX and IECEx standards define where and how electrical equipment can be safely operated in potentially explosive atmospheres. These markings indicate protection level, gas or dust classification, and temperature limits. What Is ATEX? ATEX stands for "Atmosphères Explosibles", meaning Explosive Atmospheres in French. It requires that the product is safe, and carries a label indicating the conditions under which it is approved for use. Such equipment carries standardized explosion-protection markings defined by international standards including IEC 60079, ATEX Directive 2014/34/EU, and NFPA 70 (NEC). The equipment Group I is subdivided into the Categories M1 and M2: The equipment in this category is intended for use in both underground parts of mines and those parts of surface installations of such mines that are endangered by firedamp and/or combustible dust.
