  1. Non-Destructive Testing: New Methods and Qualification of Personnel TAIEX Workshop on the implementation of the Pressure Equipment Directive (PED) Bucharest, 27 February - 1 March 2007

  2. contractor: Who has qualified your NDT personnel?

  3. Annex I chapter 3.1.3 3.1.3. Non-destructive tests For pressure equipment, non-destructive tests of permanent joints must be carried out by suitable qualified personnel. For pressure equipment in categories III and IV, the personnel must be approved by a third-party organization recognized by a Member State pursuant to Article 13. qualified personnel.

  4. Recommended Practice No. SNT-TC-1A 1984, 1988, 1992, 1996 or 2001 Edition EN 473:2006-01 Non destructive testing - Qualification and certification of NDT personnel - General principles Certification by employer third-party organisation SNT-TC-1A EN 473 ISO 9712 ISO 9712:2005-02 Non destructive testing - Qualification and certification of NDT personnel and Technical Corrigendum 1:2006-11

  5. Certification by employer third-party organisation SNT-TC-1A EN 473 ISO 9712 employer maintains system for qualification, certification and surveillance of NDT personnel employer uses external system for qualification, certification and surveillance of NDT personnel of a certification body employer authorises NDT personnel

  6. Proved independence from company interests EU / worldwide recognised Handsome system for SMEs Adopted to company needs Direct surveillance Quite flexible Certification by employer third-party organisation SNT-TC-1A EN 473 ISO 9712

  7. EN 473 / ISO 9712 NDT methods: AT Acoustic emission ET Eddy current LT Leak testing MT Magnetic testing PT Penetrant testing RT Radiographic testing UT Ultrasonic testing VT Visual testing EN 473 Applicable for other NDT methods infrared thermographic testing and strain testing

  8. EN 473 / ISO 9712 Requirements: Certification body Comply with ISO / IEC 17024 Conformity assessment General requirements for bodies operating certification of persons Authorised qualifying bodies Examination centre Employer

  9. EN 473 / ISO 9712 Requirements (cont.): Qualification levels Competence of level 1, 2 and 3 personnel Responsibilities of level 1, 2 and 3 personnel level 1: perform test acc. written practice, documentation level 2: level 1 + select technique, design written practice level 3: level1+2 + select method, define procedures and criteria, manage qualification examination, …

  10. EN 473 / ISO 9712 Requirements (cont.): Certification Training Industrial experience Qualification examinations Certificates

  11. EN 473 / ISO 9712 Problems: Content of training not defined Syllabus - IAEA-TECDOC-628 revision 1Training guidelines in non-destructive testing techniques; 2002 edition - ISO/TR 25107:2006-07 Non-destructive testing - Guidelines for NDT training syllabuses No regulations for other methods e.g. such as: UT wall thickness measurement RT film evaluation EN 473 not fully harmonised with ISO 9712 EN 473 not applied by all industrial sectors

  12. EN 473 / ISO 9712 Benefits: Widely distributed in Europe over 120 000 certificates Broad acceptance Reference in product standards EN 13445 Unfired pressure vessels Part 5 - Inspection and Testing

  13. In Germany: Notified by ZLS Central Office of Safety of the German Länder ISO / IEC 17024 + “delta” Annex I chapter 3.1.3 3.1.3. Non-destructive tests For pressure equipment, non-destructive tests of permanent joints must be carried out by suitable qualified personnel. For pressure equipment in categories III and IV, the personnel must be approved by a third-party organization recognized by a Member State pursuant to Article 13.

  14. EFNDTMultilateral Recognition of NDT Personnel Certification Schemes Certification Body seeking recognition of its system National NDT society being member of EFNDT or ICNDT Compliance with EFNDT Code of Practice Accreditation by EA signatory member or Recognition by governmental department/agency or Audit by EFNDT Certification Executive Committee (CEC) EN 473 www.efndt.org ISO 9712 ISO / IEC 17024

  15. Digital Techniques Radiology with Computer Radiography Radiology with Real Time Detectors

  16. Image plates versus radiographic film Much larger dynamic range Large wall thickness differences with one “shoot” Reduced exposure time Reduced dose rate Multiple use No chemistry, no dark room Scan time 10 sec to 120 sec

  17. Image plates versus radiographic film EN 14784-1:2005-11Non-destructive testing Industrial computed radiography with storage phosphor imaging plates Part 1: Classification of systems EN 14784-2:2005-11Non-destructive testing Industrial computed radiography with storage phosphor imaging plates Part 2: General principles for testing of metallic materials using X-rays and gamma rays

  18. Image plates

  19. Realt time detectors Varian flat panel Detector radiation produces light flashes which are stored in photo diodes output via transistors

  20. Qualification Digital Radiology film-less radiographic testing multi-sectorial Level 1 Level 2 } Qualification and certification acc. EN 473
