30、en 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. An added incentive stems from the worldwide comparabi
31、lity of a wide range of industrial applications requiring common non-destructive testing approaches.When certification of NDT personnel is required in product standards, regulations, codes or specifications, it is important to certify the personnel in accordance with this International Standard. Whe
32、n latitude is provided in the criteria within this International Standard, the certification body has the final decision in determining specific requirements.When there is no requirement in legislation, in standard or in the order for certification of NDT personnel, it is for employers of such perso
33、nnel to decide how to assure themselves that they are competent to do the work assignments. Thus, they may employ people who are already certified or they may apply their own expertise so as to assure themselves that their employee has the necessary competence. In this last case, prudent employers w
34、ould no doubt use this International Standard as a reference document.5 EN ISO 9712:2012 (E) DIN EN ISO 9712:2012-12 1 ScopeThis International Standard specifies requirements for principles for the qualification and certification of personnel who perform industrial non-destructive testing (NDT).NOTE
35、 1 The term “industrial” implies the exclusion of applications in the field of medicine.The system specified 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 metho
36、d or technique is covered by International, regional or national standards or the new NDT method or technique has been demonstrated to be effective to the satisfaction of the certification body.NOTE 2 CEN/TR 147485can be used as guidance.The certification covers proficiency in one or more of the fol
37、lowing methods:a) acoustic emission testing;b) eddy current testing;c) infrared thermographic testing;d) leak testing (hydraulic pressure tests excluded);e) magnetic testing;f) penetrant testing;g) radiographic testing;h) strain gauge testing;i) ultrasonic testing;j) visual testing (direct unaided v
38、isual tests and visual tests carried out during the application of another NDT method are excluded).NOTE 3 This International Standard specifies requirements for what are, in effect, third party conformity assessment schemes. These requirements do not directly apply to conformity assessment by secon
39、d or first parties, but relevant parts of this International Standard can be referred to in such arrangements.NOTE 4 Wherever gender specific words such as “his”, “her”, “he” or “she” appear in this International Standard, the other gender is also applicable.2 Normative referencesThe following refer
