IECEx

The International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres (IECEx) is an internationally used process to certify electrical equipment used in hazardous locations.

The code defines a system to classify locations prone to explosive atmospheres caused by gases, dusts, or fibers for example. The main goal of the International Electrotechnical Commission IEC with the IECEx regulation is to reach global harmonization of codes governing use of electrical apparatus in hazardous locations. IEC promotes mutual acceptance of evaluations and reports among the testing labs and certifying bodies.
