  1. Non-Destructive Testing (NDT) Implementation of the Pressure Equipment Directive TAIEX workshop INT MARKT 12009 12.April 2005 in Bratislava, Slovakia German Society for NDT – Berlin - Hannelore Wessel

  2. Introduction • Standard NDT methods • NDT and PED • EN standards • EN 473 – Personnel Qualification and Certification • EFNDT Non-Destructive Testing (NDT)

  3. Tasks of NDT • GENERALLY • Detection and quantitive descriptionof deviations without • distroying the usability of inspected specimen. • IN PARTICULAR • Detection of rough structure defects at the surface • of the test specimen and inner defects. • Sizing of these defects. • Detection of microstructure characteristics or defects. • APPLICATION of NDT • During the manufacturing process within general quality assurance • processes. • During in-service inspection, e.g., for lifetime prediction. Introduction

  4. Diagnostic and judgement within NDT Defect Detection Classification Analysis crack Quantification Judgement not acceptable Introduction

  5. Visual testing VT Penetrant testing PT Radiography RT Magnetic testing MT Ultrasonic testing UT Eddy current testing ET Acoustic emission AE Infrared thermography IRT Standard NDT methods

  6. EN standards National standards GPSG 6. GPSGV Einfache Druckbehälter Company standards Device and Products Safety Law Directive 97/23/EG of the European Parliament and of the Council of 29 May 1997 on the approximation of the laws of the Member States concerning PRESSURE EQUIPMENT PED and standards

European standards CEN Technical Comittee TC 54 Unfired pressure vessels BSI TC 267 Metallic industrial piping AFNOR TC 268 Shell boilers AFNOR TC 269 Water-tube boilers DIN Product Secretariat EN13445-5 Unfired pressure vessels; Inspection and Testing EN13480-5 Metallic industrial piping; Testing EN 12953-5 Shell boilers; Inspection during construction, documentation and marking of pressure parts of the boiler EN 12952-6 Water-tube boilers and auxiliary installations; Inspection during construction, documentation and marking of pressure parts of the boiler European standard European standards

  8. Classification of NDT standards CEN TC 138 N 623 Classification of NDT standard in the frame of Pressure Equipment Directive 03.03.2002 old: new: H Harmonised standards Hs Harmonised supporting standards S Supporting standards Type 1 Type 2 European standards

  9. Classification of NDT standards • Type 1 • Technical solution for at least one ESR: • in the standard itself • through reference to another standard • Informative Annex ZA • Examples: • Product standards • Material standards • Personnel qualification (EN 473) European standards

  10. Classification of NDT standards • Type 2 • Standard with basic rules, supporting fulfillment of ESRs • Examples: • Basics • Terminology • NDT methods European standards

  11. Harmonisation of technical legislation Placing safe products on the market Free movement of goods NDT and PED
