ATEX, IECEx, and North American schemes share technical roots in IEC standards but differ in marking, quality assurance, and market surveillance expectations.
This article highlights considerations for Decommissioning and Removing Ex Equipment Safely under maintenance programs themes. It is educational and not a substitute for project-specific standards, certificates, or AHJ rulings.
Non-electrical equipment (e.g., pumps, gearboxes) falls under ATEX 2014/34/EU Category rules and machinery integration with ignition hazard assessment.
Cable glands, conduit seals, and enclosure entries are part of the certified assembly; torque, thread type, and compound fills must match certificate conditions.
The IECEx scheme issues Certificates of Conformity (CoC) and relies on IECEx OD procedures; many national regulators accept IECEx with local registration steps.
Map your equipment EPL and type of protection to the classified area, then verify installation conditions of use, cable entries, grounding, and maintenance intervals. Keep declarations and certificates version-controlled.
