What standard must an inspector be certified to perform radiography?

• A. AWS D1.1
• B. CSA W178.2, CGSB 48.971
• C. ISO 9001
• D. ASME IX

Answer: (B)

Radiographic inspection is an NDT method, so the inspector must be certified under recognized NDT personnel certification standards. In Canada, the standards that specify the qualifications for radiography personnel are CSA W178.2 and CGSB 48.971. They define the knowledge, skills, and examinations needed for radiographic testing and include requirements for radiation safety and film interpretation. Without certification to these standards, performing radiography isn’t considered compliant.

The other standards listed don’t fit this need. AWS D1.1 and ASME IX are welding codes/qualification standards, not NDT personnel certification. ISO 9001 is a quality management system standard and doesn’t certify individuals for radiographic work.
