IECEx provides a means for manufacturers, regulators and users of equipment used in hazardous areas to address the risk of fires or explosions from flammable gases or dusts. Testing and certification of equipment, services and competence of persons to international standards facilitates the sale of safer products internationally at a lower cost.
This is achieved through the Conformity Assessment process where approved IECEx Certifying Bodies (ExCBs) conduct testing of Ex equipment to relevant IEC Standards (Equipment Scheme), and the manufacturer producing the Ex equipment remains under audit surveillance ensuring they have a quality management system to replicate the test sample during production. This is referred to as the Quality Assessment Report (QAR). The final step is then issuing the manufacturer with an IECEx Certificate of Conformity (CoC) which the controlled copy (electronic version) is available from the IECEx website. The IECEx CoC includes the summary reports from the laboratory test report of the equipment (ExTR) and the surveillance audits (QARs)
In addition to the preparation of International Standards, the IEC facilitates the operation of Conformity Assessment Systems. One such System is the IECEx System.
The IECEx System comprises the following:
- The IECEx Certified Equipment Scheme
- The IECEx Certified Service Facilities Scheme
- The IECEx Conformity Mark Licensing System
- The IECEx Certification of Personnel Competencies (CoPC)
What Is The Difference Between Iecex And ATEX
- Having a single Qualification Process for the assessment and evaluation of Certification Bodies and Test Laboratories to ensure that they have the necessary test equipment and facilities with staff holding the necessary level of technical expertise to conduct testing and certification.
- Establishing a single way of conducting Ex testing and certification – we refer to this as doing Ex certification the “IECEx Way”. As an illustration, it is acceptable under ATEX to rely solely on a manufacturer’s declaration for Zone 2 equipment (Ex ‘n’) whereas for IECEx we do not discriminate between Zone 0, 1, 2. All equipment under IECEx must be independently tested and certified in order to carry the IECEx certificate number and have an IECEx Certificate issued on the IECEx website.
- Targeted Jurisdiction for ATEX is the European Union but does get used on a voluntary basis outside EU
- ATEX requires compliance with the EHSR listed in Annex II and uses compliance with Standards as a “deemed to comply with EHSR requirements” meaning that strict compliance with Standards is NOT a requirement of ATEX. However most manufacturers use standards as their means to demonstrate compliance with the EHSRs
- Bodies offering ATEX services are known as “Notified Bodies” (ExNB). These bodies are qualified by the official body within their own country with the official body in the country issuing a notification to the EU Commission.
- A certificate issued by an ExNB is called “EU Type Examination Certificate” and is not a Certificate of Conformity.
- The assessment and testing/certification process of ATEX as with EU Directives is risk-based, meaning that for lower risk areas like previous zone 2 or Ex n, ATEX allows full manufacturer’s declaration without the involvement of an ExNB When it comes to IECEx
- Targeted Jurisdiction is the world, all countries
- As such, IECEx is a true International Certification Scheme where full compliance with IEC International Standards is required
- Rather than being qualified within a certification body or Test Lab’s own country, IECEx Certification Bodies (ExCB) and IECEx Test Labs (ExTL) are evaluated and qualified according to a single international process managed and approved by the single International IECEx Management Committee. Each ExTL and ExCB is visited and assessed by an expert team of assessors from IECEx.
- IECEx operates a Technical Secretariat with the IECEx Executive Secretary appointed with the Chief Executive Officer Function of the Scheme to handle day-to-day matters, reporting to the IECEx Executive and Management Committee
- ExCBs issue IECEx Certificates of Conformity that require that samples be fully tested against the Standard regardless of the zone of use of the product.
- IECEx Certificates are ALL publicly available for full viewing at the IECEx Website. This provides a single central On-Line location where Certificates issued by all IECEx approved ExCBs are located. In effect, we say if the IECEx certificate does not appear on the website then it is not issued.
- IECEx is the only Certification scheme to be formally endorsed by the United Nations as the “world’s best practice and recommended model” for use by regulators when regulating the use of Ex equipment and Services.
The point to understand is that ATEX has been set up and works effectively within EU where there exists EU legislation as the overarching requirement.
As IECEx operates globally across many national and regional jurisdictions, the IECEx rules governing acceptance of ExTLs, ExCBs, and the process of certification need to be comprehensive to ensure that confidence and integrity in IECEx certifications are maintained.

So while from a legislative perspective, all that is required to sell Ex products in the EU is ATEX, customers are asking for IECEx as well.
