[en] Test procedures in the nuclear sector are specified in the ASME rules and in the European and German ENIQ secification. In spite of differences between these catalogues of rules, their central point of qualification consists in measurements in relevant test pieces. Investigations of this kind have been carried out at MPA Stuttgart since decades ago. The procedure, influencing parameters and current possibilities of MPA are presented. By concentrating on the technical aspects of qualification, economically efficient and if necessary also short-term qualification of nondestructive tests is possible. (orig.)

[en] Short communication

[en] The proceedings contain 29 lectures and 43 posters which were presented in Trier at the annual meeting of the DGZfP in May 1990. The contributions report on further development of non-destructive testing methods towards more reliability, both of inspections and with regard to interpretation of the results. (MM)

[en] The two volumes contain all 93 lectures and posters. 34 contributions are presented as separate records in the data base. (HP)

[en] ENDEF, an initiative of the European Commission, DG XVII (Energy) was well supported by the European industrial institutions working in assistance with nuclear industrial organisations in the CEEC's (Central and Eastern European Countries) and NIS's (New Independent States). This Forum provides effectively a platform for open discussion between representatives of industrial actors active in the NDE (Non Destructive Examination)/ISI (In Service Inspection) field with the purpose to establish a co-operation pattern between qualified representatives of the EU (European Union) industry to offer a better co-ordinated and well defined assistance to the CEEC's and NIS in the field of NDE/ISI, and to lay the ground for further industrial co-operation. ENDEF developed a strategy to follow for the establishment of co-operation projects. This strategy is now used to understand the extent of past or present assistance projects and to identify the areas where more co-operation is needed. ENDEF encourages the creation in the NIS's and CEEC's of similar forums in order to increase the co-operation and co-ordination. ENDEF is also working in perfect agreement with the European Network ENIQ, piloted by the European plant operators. This identity of views lead to the leadership by the ENDEF co-ordinator of the ENIQ Task 3 involving Applications of the European Methodology for ISI qualification in the CEEC's and NIS's and presently fully integrated in ENDEF.

[en] A survey is given of the principles of the different methods of nondestructive materials testing. Electromagnetic and acoustic waves: visuel light-optical methods; laser methods; radiographic methods; γ-ray methods; thermographic methods using ultra-sound; acoustic emission analysis. Heat flux: testing with liquid crystals. Electromagnetic fields: magna flux methods; stray-flux methods; hysteresis methods; eddy-current methods. Mechanical-physical methods: microsclerometric measurement; photoelastic surface layer methods. (orig.)

[en] The current problem solutions and the latest research results from all areas of nondestructive materials testing are presented in 63 poster contributions: Industrial radiography, ultrasonic testing, eddy current testing, thermography, acoustic emission testing, penetrant testing, testing of new materials, parameter determination, the application of computers and the application of mathematical models.

[en] The lecture is more concerned with the basic questions of using non-destructive testing than with its special processes, techniques and devices. In the context of this basic consideration, one must deal with the application of non-destructive testing for quality assurance in the manufacture of products and in operating plants. Assuring the quality of the tests themselves is part of the subject; both the choice of the processes and techniques suitable for the aim of testing and the skilful execution of the test work require a certain quality, which must be assured if non-destructive testing is to play its intended part in the quality assurance of products and in the operation of plants.
