In order for equipment to receive a conformity “Ex” marking under the IECEx System, it must obtain a certificate of conformity. To obtain a certificate of conformity, there must be:
- An accepted IECEx Quality Assessment Report (QAR)
- An accepted IECEx Test Report for type testing (ExTR)
Products with the IECEx conformity mark have received the IECEx Certificate of Conformity, which confirms the product has the appropriate protection for use in explosive atmospheres and that it has been manufactured under a system subject to ongoing surveillance by Certification Bodies. The marking also indicates that the product can be supplied to the market without the need for additional testing. The exception is increased safety (EX e) motor protection type, which must always be tested with the drive it is used with.
