Box 100 A-1400 Vienna, Austria GUIDEBOOK FOR THE FABRICATION OF NON-DESTRUCTIVE TESTING (NDT) TEST SPECIMENS IAEA, VIENNA, 2001 IAEA-TECDOC-TCS-13 ISSN 1011–4289 © IAEA, 2001 Printed by the IAEA in Austria June 2001 FOREWORD The International Atomic Energy Agency (IAEA) is promoting the industrial applications of radiation technology, which include non-destructive testing (NDT) under its various programmes such as individual country technical co-operation (TC) projects, regional projects and co-ordinated research projects (CRPs). The NDT technology is essentially needed for the improvement of the quality of industrial products, equipment and plants all over the world, especially in the developing Member States. An important feature of the NDT programme, notably in the East Asia and Pacific (RCA) region, has been the establishment in each of the Member States of a system for training and certification of NDT personnel based on the International Organization for Standardization standard ISO/FDIS 9712-1999, “Nondestructive Testing: Qualification and Certification of Personnel”. The main focus is the creation of a core group of personnel who are trained and qualified to establish the training and certification process in their respective countries. An important requirement for such a process is to have appropriate training materials that include, among others, NDT test specimens having standard known dimensions and in-laid artificial defects simulating the real defects that can or may occur in industrial components. NDT test specimens constitute a very important part of training and certification of NDT personnel and are important for carrying out actual inspection and testing, and for achieving international harmonization of NDT practices. Naturally, therefore, there is a need to pay greater attention to this subject. A number of seminars and workshops on NDT test specimens have been organized for this purpose during the past years under various RCA regional projects while a number of additional activities, such as regional training courses and seminars, are planned for the future. It has always been felt that there is a strong need to have a proper guidebook addressing various issues and problems related to the fabrication of NDT test specimens. Such a book would be useful for conducting training courses on this theme in the future, thereby spreading the know-how for the fabrication of NDT test specimens and establishing and strengthening education, training and certification process in many Member States on a sustainable basis. In view of the above, the IAEA organized an advisory group of experts to develop a Guidebook for the Fabrication of NDT Test Specimens. The experts consulted the ISO/FDIS 9712-1999 requirements for training and certification of personnel and the suitability of various types of NDT test specimens that are needed to meet such requirements. A set of appropriate NDT test specimens, as we
