Manage Your NDT Certification

Once you have achieved your non-destructive testing (NDT) certification to the CAN/CGSB-48.9712-2014 standard, it is your responsibility to keep an eye on its expiry date and to renew and recertify it on time or to revalidate it if necessary.

Renewal, recertification and revalidation in non-destructive testing


Renewal of your NDT certification is a process that extends the period of its validity. You can renew your NDT certification shortly prior to its expiry. Renewals are valid for a period of up to five years (60 months or less).


Recertification is a process that maintains the validity of your certification through examination. You are required to recertify your certification before the end of your second period of validity, approximately 10 years from initial certification or last recertification (120 months or less).

If you fall within the transitional period for recertification, you must complete your recertification process by your next renewal expiry date. Candidates whose initial certifications were obtained in 2010 or earlier (with a previous expiry date of December 31, 2015), 2011 or earlier (with a previous expiry date of December 31, 2016), and 2012 or earlier (with an expiry date of December 31, 2017), respectively, are considered to be within the transitional period for recertification.


Revalidation is needed when your NDT certification becomes invalid for one of several reasons, such as a significant interruption in NDT work experience, failure to meet eye examination requirements, or violating the code of conduct.

The processes for renewal, recertification and revalidation are different, so please ensure you read the instructions for the process that you need to follow in your circumstances.
