[en] The main task of an NDT engineer is to select the best method, considering the cost-benefit value of different available systems and taking into account the special existing constraints. The aim of the paper is to suggest a tool that will enable characterization of measuring systems. The derivation of the characterization parameters and functions has to be general, i.e., suitable for all possible measuring methods, independent of their principle of operation. Quite often the properties measured during the NDT procedure are not the wanted ones, but there must be a correlation between the measured property and the performance of the product. One has to bear in mind that the ultimate choice between systems is not, in practice, just based on the mathematical optimization approach that is presented. Factors like cost-benefit, availability of trained manpower, service, real-time information, weight, volume, etc., may be crucial problems, and they may well dictate the final selection

[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] Ultrasonic inspection is one of the most widely used methods for nondestructive inspection. The beam of high-frequency sound wave, ultrasonic wave, is introduced into the material. It travels through the material with some attendant loss of energy and can be reflected at interfaces. The reflected beam is detected and analyzed. Ultrasonic inspection is used to detect flaws in metal parts as well as in welded, brazed and bonded joints during research work and developing production and service. It is also used to detect and locate porosity, pipe, and flakes. In addition, it can be used for the measurement of metal thickness. Ultrasonic inspection is therefore used for quality control and material inspection in all major industries

[en] The article presents the modern methods of research of building materials (such as styrofoam, cement, concrete admixtures, etc.), applied in the Far Eastern Federal University. The latest equipment described for these studies and modern methods of testing. (paper)

[en] This invention concerns suction pads for supporting loads. Specifically, the suction pad is part of a pair of pads located at the ends of a bridge forming a vehicle for transporting instruments for the non-destructive testing of a large vessel intended to contain a fuel assembly for a nuclear reactor immersed in a liquid metal coolant. For example, the vehicle is of the type described in the French patent application filed this day under the heading 'Vehicle for transporting instruments for testing against a wall'
