The problems of automation of control processes in the non-destructive testing units are considered. The analysis of normative and technical documents is carried out and the main components of the non-destructive testing system and their parameters are determined. The developed software and relational database for monitoring and control of the unit have been integrated into trial operation in the non-destructive control units of the freight car repair company. Based on the statistical processing of control results, the possibility of assessing the efficiency of NDT inspectors and control devices was shown. The use of a network database and developed software makes it possible to improve the efficiency of control processes in the units of non-destructive testing by reducing the time spent on analysis and deciding on scheduled activities, the formation of reporting documentation.

A comprehensive analysis of the concept “sector”, as one of the main components of the certification area of a specialist in non-destructive testing (NDT) in accordance with the requirements of the international standard EN ISO 9712, was carried out. Features and differences of the lists of sectors regulated by regulatory documents that establish the requirements for certification of NDT personnel are considered in the voluntary (DSTU EN ISO 9712) and legislatively regulated (NPAOP 0.00-1.63-13) areas of Ukraine. The features of the areas of accreditation of Personnel Certification Bodies (OSB) in the field of non-destructive testing of Ukraine and some countries of the European Union are considered. The analysis of sectors with which non-destructive testing personnel is certified was performed. Personnel certification bodies accredited by the National Accreditation Agency of Ukraine (NAAU) and national accreditation bodies of the Great Britain, Germany and Nordic countries in accor­dance with the requirements of the international standard EN ISO / IEC 17024. The differences in product and manufacturing sectors re­gulated by the standard EN ISO 9712 and established by the areas of accreditation of PCB in the field of non-destructive control of Ukraine and selected European countries. The basic principles are stated in accordance with which an additional (national) sector should be created. On the example of the analysis of differences in the production sectors “production” and “control before and during ope­ration, including production” according to EN ISO 9712, various aspects of non-destructive testing that affect the criteria for the formation of additional (national) production sectors were considered. The possibility and appropriateness of introducing national sectors into the certification procedures of Personnel Certification Bodies for non-destructive testing in Ukraine are considered.

The inspection and control of sodium-cooled fast reactors (SFR) is a major issue for the nuclear industry. Ultrasonic solutions are under study because of the opacity of liquid sodium. In this paper, the use of leaky Lamb waves is considered for non-destructive testing (NDT) on parallel and immersed structures assimilated as plates. The first phase of our approach involved studying the propagation properties of leaky Lamb waves. Equations that model the propagation of Lamb waves in an immersed plate were solved numerically. The phase velocity can be experimentally measured using a two dimensional Fourier transform. The group velocity can be experimentally measured using a short-time Fourier transform technique. Attenuation of leaky Lamb waves is mostly due to the re-emission of energy into the surrounding fluid, and it can be measured by these two techniques.

This paper outlines the standardisation process for the XRPD method that is currently being considered by a Working Group (WG10) of Technical Committee 138 "Non-destructive Testing" of the European Committee for Standardisation CEN. Several Standard Documents are on the verge of being released. These documents concern the general principles of (X-ray) diffraction, its terminology, and the basic procedures applied. Another document concerns the instruments used and it offers procedures to characterise and control the performance of an X-ray diffractometer properly. It is intended to issue Standard Documents on specific methods, e.g. determination of residual stresses. In fact work is in progress on this subject. The Standard Documents can be used by industry, government organisations, and research centres with activities related to safety, health and the environment, as well as for educational purposes.

The testing principle of metal ultrasonic is using ultrasonic probe to scan in the work-piece surface, and acquire the probe of reflection signal which is sent to computer to analysis by the ultrasonic data acquisition card so as to detect and locate defects in surface of the parts. This system designed a unique scanning structure using the principle of ultrasonic detection and scans the hardware and software control system to realize internal shape detection for different shape of work-piece.

The aim of this study was to evaluate cementitious matrices properties by partial replacement of Portland cement by silica fume (SF) or by rice husk ash (RHA), and their application in nonbearing hollow blocks, tested by destructive and non-destructive methods. The following mixtures were produced: reference (100% of Portland cement) and Portland cement replacement (10% by mass) with SF or RHA. The non-destructive testing showed that the highest values of UPV were obtained for SF-based blocks and RHA-based blocks. The destructive test showed better results for SF-based blocks, but there was no statistical difference between the RHA-based and control ones.
