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 Custom Enclosures: Prototype Testing Strategy under equipment certification themes. It is educational and not a substitute for project-specific standards, certificates, or AHJ rulings.
Grounding, bonding, and static control keep touchable metalwork and raceways at equipotential levels compatible with flameproof and increased safety concepts.
UL and CSA listings for hazardous locations map protection techniques to North American categories; dual marking with ATEX/IECEx is common on global product lines.
Canadian installations reference similar concepts in the CEC; always confirm edition year and provincial amendments.
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.
Book a consultation with HazloLabs when markets or standards change mid-project—early alignment saves retest cycles.
