The OBAC Institute conducts obligatory and voluntary assessment of product conformity with ATEX No. 2014/34/UE Directive: Equipment and protective systems intended for use in potentially explosive atmospheres.

The OBAC Institute, as the first private Polish certification body, is approved by the International Electrotechnical Commission IECEx for testing, inspection and certification of explosion-proof products in accordance with the requirements of IEC standards.

OBAC’s test reports ExTR are accepted by Chinese Governmental MA Certification Centre in Bejing.

OBAC’s test reports ExTR are accepted by EAC Certification Bodies in Russia, Belarus, and Kazakhstan.
