Notified body certificate validity — maximum five years
A CE certificate issued by a notified body under MDR/IVDR is valid for the period it indicates, which may not exceed five years; on application by the manufacturer the validity may be extended for further periods each not exceeding five years, based on a re-assessment under the applicable conformity assessment procedures. Any supplement to a certificate remains valid as long as the certificate it supplements is valid.
- Re-certification reviews and renewal of certificates are required at least every five years.
- The Croatian national registration (unique registration number, EUDAMED device registration) is not time-limited in the same way and does not expire with the certificate, but the device may no longer be placed on the market if the certificate lapses without a transitional basis.
