Education of personnel engaged in non-destructive inspection, including formal training, and certification, is probably the greatest single factor affecting the quality of non-destructive inspection.

Certification systems require that employers and other stakeholders participate in identifying the knowledge, skills and abilities (competencies) than individual must have to do a job properly.

This International Standard specifies requirements for principles for the qualification and certification of personnel who perform industrial non-destructive testing (NDT).

The effectiveness of Non Destructive Testing is primarily dependent upon the capabilities of the NDT Personnel. Hence, Qualification and Certification of NDT Personnel is of great importance for the enforcement of Quality.
