X-Ray Fluorescence Analyzer Operator Certification

Online Examination System for select CAN/CGSB-48.9712 and XRF multiple-choice exams

All written multiple-choice examinations for CAN/CGSB-48.9712 (NDT) and XRF are being updated to a computer-based electronic format (in-person live proctored). Examinations are being launched in the online examination system via the following schedule:

  • February 1, 2023 (ongoing): Magnetic Testing (MT) and Penetrant Testing (PT)
  • June 16, 2023: Ultrasonic Testing (UT), Eddy Current Testing (ET) and X-Ray Fluorescence (XRF)
  • June 30, 2023: Radiographic Testing (RT) EMC sector (including Radiation Protection exam)
  • July 14, 2023: Radiographic Testing (RT) A/S sector
  • July 28, 2023: Level 3 Basic (all methods)

Once candidates receive official electronic written examination authorization from the NRCan NDTCB, they can register for and book their examinations through the online exam system portal and select the closest available examination centre. Candidates who have valid written examination admittance and registration forms for the methods/examinations listed above must submit a request to the NRCan NDTCB by email to receive electronic written examination authorization. Immediately after completing an exam, candidates can view unofficial examination results through the online examination system.

Paper-based NDT multiple-choice examinations will be phased out, however paper-based XRF examinations will be maintained for use by select special XRF examination centres (SXECs). Additionally, Special Written Examination Centres (SWECs) for NDT and XRF written exams are no longer available. For more information, please contact the NRCan NDTCB.

NRCan NDTCB Service fees update

COVID temporary accommodations and extensions

In April 2020, The NRCan NDTCB implemented temporary accommodations and extensions relating to initial certifications and renewals/recertifications for select candidates and expiry dates. Some of these extensions have already expired, with all extensions for renewal and recertification expiring by December 2024. It is the responsibility of certification candidates and certificate holders to keep track of all expiry dates and due dates and manage their applications and certifications accordingly. Please visit our NDT Certification Body COVID Program Updates page for more information.

The Natural Resources Canada (NRCan) x-ray fluorescence (XRF) analyzer operator certification program comprises radiation safety training and examination components that are based on the non-destructive testing method of radiographic testing.

The NRCan National Non-Destructive Certification Body (NDTCB) developed and implemented its XRF certification program in collaboration with Health Canada. Health Canada publishes safety codes that are incorporated into the Canada Labour Code, which applies to federally regulated sectors. An addendum specifically applicable to portable hand-held x-ray tubes based on open-beam XRF devices falls within the scope of Safety Code 32. It requires individuals who use “portable hand-held x-ray tube based open-beam XRF” devices to be certified.

The NRCan (NDTCB) has adopted International Standard ISO 20807:2004 (with modifications) as the basis of its XRF certification. The certification scheme and guidelines in the current XRF Examination Preparation booklet supersede any differing details from the ISO 20807:2004 certification standard.


  • Understands the importance of impartiality and takes it seriously
  • Has processes to manage potential conflicts of interest and ensure all certification activities are objective
  • Is solely responsible for, retains authority for, and does not delegate its decisions relating to certification, including the granting, maintaining, recertification, expansion and reduction of scope, suspension, or withdrawal of certifications

What it means to be XRF certified

Certified XRF analyzer operators must have at least basic knowledge of XRF theory and applications, as well as an understanding of the principles and practices of radiation safety as they relate to portable open-beam XRF analyzers. They must pass examinations, submit application forms with photos and identification, and maintain valid certification.
