This International Standard establishes principles for the qualification and certification of personnel who perform industrial non-destructive testing (NDT). NOTE 1 The term 'industrial' implies the exclusion of applications in the field of medicine. 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. The 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 for the employer. Where required by regulatory requirements and codes, the authorization to operate shall be given in writing by the employer in accordance with a quality procedure that defines any employer required job -specific training and examinations designed to verify the certificate holder's knowledge of relevant industry code(s), standard(s), NDT procedures, equipment, and acceptance criteria for the tested products. NOTE 2 This standard specifies requirements for what are in effect third-party conformity assessment schemes; These requirements do not directly apply to conformity assessment by second or first parties but relevant parts of this standard can be referred to in such arrangements.
