ISO 9712 is an international organization for standardization that specifies requirements for the qualification and certification of personnel who perform industrial non-destructive testing (NDT) in the following methods: 

• Acoustic emission testing 
• Eddy current testing 
• Leak testing (hydraulic pressure tests excluded) 
• Magnetic testing 
• Penetrant testing 
• Radiographic testing 
• Strain gauge testing 
• Thermographic testing 
• Ultrasonic testing 
• Visual testing (direct unaided visual tests and visual tests carried out during the application of another NDT method are excluded) 

The system specified in ISO 9712 is also applicable to other NDT methods or to NDT techniques within an established NDT method, provided a comprehensive scheme of certification exists and the NDT method or NDT technique is covered by international, regional or national standards or the NDT method or the NDT technique has been demonstrated to be effective to the satisfaction of the certification body.

Why should you use ISO 9712 - Qualification and certification of NDT personnel?  

Since the effectiveness of any application of non-destructive testing (NDT) depends upon the capabilities of the persons who perform or are responsible for the test, a procedure has been developed to provide a means of evaluating and documenting the competence of personnel whose duties require the appropriate theoretical and practical knowledge of the non-destructive tests they perform, specify, supervise, monitor or evaluate.  

ISO 9712 provides its users with guidelines for the required responsibilities, levels of certification, eligibility, examinations, and certifications for the NDT personnel.
