A note about transitioning to the new 2022 standard

NRCan NDTCB is now issuing non-destructive testing (NDT) certifications under the CAN/CGSB-48.9712-2022 standard effective April 1, 2024. Certifications awarded prior to this new standard will be valid for the stated period of validity on the certification until the next step in the certification process (renewal, recertification, or revalidation), which will be carried out according to the 2022 standard and the new NRCan NDTCB Rules of Implementation.

Certification according to the 2014 standard and Rules of Implementation will fulfill the requirements of both the 2014 version and preceding versions of the standard. Consequently, any requirement for certification to any version of the CAN/CGSB-48.9712 standards shall be fulfilled by a valid certification according to the applicable standard at the time of issuance by the NDTCB.

This transitional framework is necessary in ensuring credible, fair and accessible mechanisms for individuals and the NDTCB to manage certification requirements with respect to variations of the ongoing standard publishing cycles.
