Conformity assessment – A passport to the world


The IEC manages three Conformity Assessment Systems – IECEE, IECEx and IECQ – that between them cover the whole range of electrotechnical sectors.


The combination of IEC International Standards and CA Systems makes products safer and more reliable, increasing consumer confidence and public safety.


All members of IEC CA Systems accept certificates issued by other members. Duplication of tests is eliminated, reducing time and cost. A manufacturer based in a non-member country can approach a certification body in any member country and have its products tested and certified.


IEC CA Systems reduce the number of steps required to obtain national certification. They take into account variations that may be included in a standard when adopted nationally and reduce trade barriers. IEC CA Systems provide a standardized approach to testing and certification.
