Explosive Atmosphere Testing

ATEX and IECEx Certifications

Explosive Atmosphere Protection Conformance

Combustible dusts and flammable gases, mists or vapors can all contribute to potentially explosive atmospheres in the workplace. For this reason, equipment and systems that are used within or in conjunction with these environments must conform to specific safety requirements. These requirements apply to all explosion-proof equipment and systems including safety, control and regulation devices, and protective components, equipment and systems. Companies that manufacture explosion-proof equipment and systems for the global market must conform to applicable standards.

These  potentially hazardous environments, also known as “Ex areas” (short for explosive areas), are found in a range of industries, including oil and gas refineries and distribution facilities,  chemical processing plants, grain  and agricultural handling, processing  and storage facilities, underground  mines, and even hospital operating  environments.

Equipment used in these hazardous environments must therefore be expressly designed to minimize such risks, and manufacturers of electrical, non-electrical, electronic, mechanical equipment and systems must ensure that their products meet the enhanced requirements of applicable regulations and standards.

For international trade, vital requirements are provided by the ATEX Directive and the IECEx system:

  • About ATEX Testing and Certification

    In the EU, all explosion-proof classification falls under the ATEX Directive (2014/34/EU). This includes anything used within, or in conjunction with potentially explosive atmospheres such as safety, control and regulation devices and protective components, equipment and systems. As a visible sign of compliance with ATEX, CE marking must be affixed to the equipment.

  • About IECEx International Certification Scheme Testing

    IECEx Certification Scheme Testing is a worldwide standard to ensure explosion proof equipment and systems are safe for use in countries that participate in the IECEx system. To be validated against the IECEx Certified Equipment Scheme, manufacturers need to obtain the Certificate of Conformity (CoC), validation of the technical report (ExTR) and the quality assurance report (QAR).
