ATEX vs IECEx: Key Differences Explained for Hazardous Area Equipment

When specifying electrical equipment for use in hazardous areas where explosive gases or dust may be present, understanding the different certification schemes is critical for compliance and safety. Two of the most common certifications are ATEX and IECEx, but many people aren't clear on the differences between them.

In this article, we'll explain what ATEX and IECEx are, the key differences between them, and what you need to know when specifying explosion proof equipment for your project.

What is ATEX?

ATEX is the European Union directive for equipment intended for use in explosive atmospheres. The name comes from the French "Atmosphères Explosibles" and it's a regulatory requirement that applies to all equipment placed on the European Union market.

Key points about ATEX:

• It's a legal requirement in the EU for equipment in hazardous areas
• Covers both the equipment itself and the manufacturing process
• Includes two directives: one for equipment (2014/34/EU) and one for work equipment (1999/92/EC)
• Certification is done by notified bodies designated by EU member states
• Products that are ATEX certified can be sold freely throughout the EU

What is IECEx?

IECEx is an international certification scheme operated by the International Electrotechnical Commission. It's based on international standards for explosion protection and provides a framework for mutual recognition of certifications among participating countries.

Key points about IECEx:

• It's a voluntary certification scheme based on international standards
• Aims to facilitate international trade in equipment for hazardous areas by providing mutually recognized certification
• Covers certification of equipment, services, and personnel
• Participated in by over 30 countries including major industrial nations across Europe, Asia-Pacific, the Americas, and Middle East

Key Differences Between ATEX and IECEx

1. Legal Requirement vs Voluntary Certification

The most fundamental difference is that ATEX is a legal requirement for any equipment placed on the European Union market, regardless of where it's manufactured. IECEx is a voluntary certification scheme that provides proof of compliance with international standards, which many countries accept but it's not always a legal requirement on its own.

2. Geographic Applicability

If you're supplying equipment for use within the European Union, you need ATEX certification. IECEx certification is useful for global trade where you need certification that's accepted in multiple countries around the world that recognize the IECEx scheme.

3. Standards Approach

ATEX defines the essential requirements for explosion protection, and references harmonized European standards that correspond to international IEC standards. IECEx is directly based on the IEC 60079 series of international standards for explosion protection.

Can Equipment Have Both ATEX and IECEx Certification?

Yes, and it's quite common. Many manufacturers choose to obtain both certifications: ATEX for access to the EU market and IECEx for global trade acceptance. This gives you maximum flexibility for supplying projects in different countries around the world.

At Youngly Tech, all of our explosion proof equipment is both ATEX and IECEx certified, giving you full compliance and global acceptance for your projects.

What Does This Mean for Your Project?

If You're Working in the European Union

You must use ATEX certified equipment for hazardous areas. This is a legal requirement, and non-compliant equipment cannot be legally placed on the market or used. Make sure any explosion proof equipment you purchase has a valid ATEX certificate from a notified body.

If You're Working Outside the EU

Requirements vary by country, but IECEx certification is widely accepted in many countries around the world including many in the Middle East, Asia-Pacific, Africa, and the Americas. Check with your local regulatory authorities to understand what certification they accept.

If You're Working on International Projects

Having both ATEX and IECEx certification gives you maximum flexibility to supply equipment to different countries around the world while maintaining the necessary certifications.
