26、on of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee
27、. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance wi
28、th the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approv
29、al by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 9712 was prepared by Technical Committee I

32、hts reserved vBS EN ISO 9712:2012ISO 9712:2012(E)IntroductionSince 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 docum
33、enting 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 comparability of a wide range of industrial applications requiri
34、ng 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. When latitude is provided in the criteria within this Inte
35、rnational 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 personnel to decide how to assure themselves that they are c
36、ompetent 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 would no doubt use this International Standard as a refe
37、rence document.vi ISO 2012 All rights reservedBS EN ISO 9712:2012Non-destructive testing Qualification and certification of NDT personnel1 ScopeThis International Standard specifies requirements for principles for the qualification and certification of personnel who perform industrial non-destructiv
38、e testing (NDT).NOTE 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
39、exists and the method 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 on
40、e or more of the following 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 testi
41、ng (direct unaided visual 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
42、 assessment by second 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 reference
