ExTC is an IECEx certified Testing Laboratory (ExTL) and performs explosive atmosphere product testing.

What is an IECEx Test Laboratory?

The IECEx System is the International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres. The objective of the IECEx System is to facilitate international trade in equipment and services for use in explosive atmospheres.

To do so, IECEx require an assessment process to be successfully completed for a facility to be accepted as an ExTL. Ex Testing and Certification has completed this assessment.

In addition, ExTC has NATA ISO17025 accreditation for testing and certification.

What does this mean?

As a certified Test Lab, ExTC can issue an IECEx Test Report (ExTR) – the first step in gaining a Certificate of Conformity, certifying a product to be used in an Explosive Environment.

We offer explosive atmosphere testing of electrical equipment, non-electrical equipment and explosive tests on diesel engines for explosive atmospheres.
