As per Rule 18 of the NRCan NDTCB’s Rules of Implementation for the CAN/CGSB-48.9712-2022 Standard, when an NDT certification that you hold becomes invalid, there are specific processes that you must follow to revalidate it.
Guidelines for revalidation
- Revalidation via recertification examination:
If a candidate (due for renewal only at the end of their period of validity) cannot meet the requirements for renewal within 12 months of the expiration date of the certification or has a significant interruption in work activity, the candidate can revalidate via recertification examination.
If the revalidation of the certificate takes place within the 12 months following the date of expiration (renewal grace period), the date of expiration of the reinstated certificate shall be no more than 5 years from the date of expiration of the original certificate. However, if the revalidation of the certificate takes place 12 months or more following the date of expiration, the date of expiration of the reinstated certificate shall be based off the date that the certificate was revalidated (a period of 5 years or less, depending on the candidate’s birth month).
- Revalidation via initial certification examinations/other requirements as applicable:
If a candidate fails all allowable examination attempts for recertification or a candidate (due for recertification at the end of their period of validity) cannot meet the requirements for recertification within 12 months of the expiration date of the certification or has a significant interruption in work activity, the candidate can revalidate via completion of initial certification examinations (and other initial certification requirements as needed/specified by the NRCan NDTCB).
If the revalidation of the certificate takes place within the 12 months following the date of expiration (recertification grace period), the date of expiration of the reinstated certificate shall be no more than 5 years from the date of expiration of the original certificate. However, if the revalidation of the certificate takes place 12 months or more following the date of expiration, the date of expiration of the reinstated certificate shall be based off the date that the certificate was revalidated (no more than a period of 5 years, depending on the candidate’s birth month).
- Revalidation as otherwise specified by the NRCan NDTCB
Revalidation for all other circumstances for which a certification is suspended or withdrawn shall be decided by the NRCan NDTCB on a case-by-case basis, allowing for precedence of previous cases and decisions where applicable.
Following revalidation in these circumstances, the date of expiration of the reinstated certificate shall be determined by the NRCan NDTCB and in any case will be no more than a period of 5 years, depending on the candidate’s birth month.
