What is a QAN/QAR?

Understanding QAN and QAR

What is QAN?

Quality Assurance Notification (QAN) complies with the ATEX Directive for the EU and UK. It applies to equipment used in hazardous zones, such as zones 1, 0, 21, and 20. Companies must complete the QAN process to sell ATEX products in Europe. A Notified Body issues QAN certification.

What is QAR?

Quality Assurance Registration (QAR) follows IECEx requirements. Similar to QAN, this is a mandatory Quality Assurance System for companies applying for an IECEx Certificate of Conformity.

Key Points to Understand

  • ISO 9001 vs. EN 80079-34: EN 80079-34 is stricter but overlaps with ISO 9001 requirements. Setting up BS EN ISO/IEC 80079-34 meets ISO 9001 standards. ISO 9001 Registration is not mandatory.
  • Combined Audits: The IECEx QAR audit scheme is quite similar to the ATEX QAN audit scheme. Manufacturers are encouraged to explore combined IECEx and ATEX audits as a cost-saving and time-efficient option.
  • Audit Cycles: The typical audit cycle for QAN and QAR spans three years, with required surveillance occurring every 12–18 months.
