ATEX vs C1D2: Comparing Certification Standards for Industrial PCs and Panel PCs
When working in hazardous environments, selecting the right industrial computer is critical. If your business operates in oil & gas, chemical processing, pharmaceuticals, or food production, you’ve likely come across ATEX and C1D2 certifications. These safety standards ensure that equipment is safe to use in explosive atmospheres, but how do they differ? Let’s break it down.
What is ATEX?
ATEX (Atmosphères Explosibles) is a European regulatory framework for equipment used in explosive atmospheres. It ensures that electronic devices, including industrial computers and Panel PCs, meet strict safety requirements to prevent ignition risks.
ATEX Classification Zones:
- Zone 0 – Explosive gas atmosphere is always present.
- Zone 1 – Explosive gas atmosphere is likely under normal operation.
- Zone 2 – Explosive gas atmosphere is unlikely but possible in abnormal conditions.
- Zone 20, 21, 22 – Similar to the above but for dust hazards.
What is C1D2?
C1D2 (Class I, Division 2) is a North American standard, primarily used in the United States and Canada, as part of the NEC (National Electrical Code). It defines hazardous locations where flammable gases or vapors may exist only under abnormal conditions.
C1D2 Classification:
- Class I – Presence of flammable gases, vapors, or liquids.
- Division 1 – Hazardous substances present under normal conditions.
- Division 2 – Hazardous substances present only in abnormal conditions.
ATEX vs C1D2: Key Differences in Hazardous Area Certifications
| Feature | ATEX (Europe) | C1D2 (North America) |
|---|---|---|
| Regulatory Body | EU Directives (2014/34/EU, 1999/92/EC) | NEC (National Electrical Code) |
| Scope | Gas & dust environments | Gas & vapor environments |
| Classification | Zone-based system (0, 1, 2, 20, 21, 22) | Division-based system (1 & 2) |
| Primary Market | Europe, UK & IECEx countries | USA & Canada |
| Use Case | Hazardous industrial environments | Industrial areas with occasional hazards |
Choosing the Right Industrial Computer
If your business operates in the UK or Europe, ATEX-certified Panel PCs are the ideal choice for hazardous environments. These computers are designed to withstand explosive atmospheres while ensuring maximum durability, reliability, and safety.
Features of ATEX-Certified Panel PCs:
- SUS316 Stainless Steel Construction – Provides superior corrosion resistance.
- Total IP66 Rating – Fully dust-tight and protected against powerful water jets.
- M12 Waterproof Connectors – Ensures a fully sealed, ruggedized solution.
- Projected Capacitive Touch – Enables seamless operation with gloves or wet conditions.
- ATEX Zone 2, Zone 22, IECEx & C1D2 Certified – Suitable for hazardous locations worldwide.
Conclusion
Understanding ATEX vs. C1D2 is crucial when selecting an industrial computer for hazardous environments. While both certifications provide safety assurances, ATEX is the preferred standard for the UK and European industries, ensuring compliance with strict safety regulations.
If you’re looking for a robust and certified ATEX Panel PC, make sure it meets the required zone classifications and includes features like stainless steel housing, full IP66 protection, and waterproof connectors.
