What is IECEx?

IECEx is an international certification system that aims to simplify the approval process for electrical and non-electrical equipment used in explosive atmospheres. Developed by the International Electrotechnical Commission (IEC), this system ensures that products comply with international standards, reducing barriers to trade while maintaining safety measures.


ATEX (Atmosphères Explosibles) is a European Union directive that governs the manufacture and sale of equipment used in potentially explosive atmospheres. IECEx, on the other hand, is an international system that goes beyond European boundaries. While ATEX focuses primarily on safeguarding the European market, IECEx offers a broader scope, aiding companies in safety compliance across the globe.

IECEx certification process

Obtaining IECEx certification can be a complex process, but it provides numerous advantages for manufacturers and end-users alike. The certification process involves the following steps:

  • Application: Manufacturers submit an application to an IECEx Certification Body, providing technical documentation and information about the equipment to be certified.
  • Evaluation: The Certification Body evaluates the equipment, testing it against the relevant international standards. This assessment includes design evaluations and testing for functionality, performance, and protection.
  • Factory inspection: Once the evaluation is complete, a team of experts conducts an on-site assessment of the manufacturer’s facilities to ensure that the production processes are consistent and comply with IECEx requirements.
  • Certification: If all requirements are met, the Certification Body issues an IECEx Certificate of Conformity, which serves as proof that the equipment has successfully met the necessary standards for use in explosive atmospheres.

Benefits of IECEx

The adoption of IECEx offers several benefits to manufacturers, end-users, and other stakeholders in the industry. Some key advantages include:

  • Global recognition: IECEx certification is widely recognized by regulatory authorities and industry bodies across the world, facilitating market access for manufacturers in multiple countries.
  • Streamlined compliance: With a unified international standard, manufacturers can avoid the need for separate certifications in each country they operate, saving both time and resources.
  • Enhanced safety: IECEx ensures that certified equipment adheres to stringent safety standards, reducing the risk of accidents and ensuring the well-being of workers in hazardous environments.
  • Competitive advantage: Being IECEx-certified can give manufacturers a competitive edge, as it demonstrates their commitment to quality, safety, and compliance.
  • Simplified supply chain: End-users can easily identify IECEx-certified equipment, simplifying the procurement process and ensuring the use of reliable and safe products.
