BS EN ISO 9712
Non-destructive testing – Qualification and certification of NDT personnel – General principles

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

Accreditation in Europe is voluntary, but assessment and approval by government appointed agencies, which may also be accreditation bodies, may become mandatory in regulatory sectors such as Pressure Equipment (Pressure Equipment Directive 97/23/EC).

The system described in this International Standard can also apply to other NDT methods, or to new techniques within an established NDT method, provided a comprehensive scheme of certification exists and the method or technique is covered by International, European, regional or national standards.  This certification covers proficiency in one or more of the following methods:

a) acoustic emission testing

b) eddy current testing

c) infrared thermography testing

d) leak testing (hydraulic pressure tests excluded)

e) magnetic testing (magnetic particle testing and flux leakage testing)

f) penetrant testing

g) radiographic testing

h) strain testing

i) ultrasonic testing

j) visual testing (direct unaided visual tests and visual tests carried out during the application of another NDT method are excluded)

Certification to this International Standard provides an attestation of general competence of the NDT operator.  It does not represent an authorization to operate, since this remains the responsibility of the employer, and the certified employee may require additional specialized knowledge of parameters such as equipment, NDT procedures, materials and products specific to the employer
