IECExThe International Electrotechnical Commission's certification system for explosion-proof electrical products refers to the certification of electrical equipment specifically used in industrial sectors such as petroleum, chemical, coal mining, light textile, grain processing, and military industries where explosive gases, vapors, dust, or fibers may accumulate in hazardous areas.



The ultimate goal of the IECEx system is to be accepted worldwide

A series of standards for electrical equipment in explosive hazardous environments developed by IEC TC31;

One certificate - IECEx Certification of Conformity;

One logo - IECEx Mark of Conformity.
