Evaluation of the Reliability of NDTesting in Russian Railway Transport

Abstract

Algorithms to estimate ultrasonic testing method based on the integrated use of indicators of reliability and accuracy are presented, and built according to the nature of techniques, features of their application and evaluation purposes (comparison of techniques, introduction of new methods, test procedures, etc.). On the basis of the main revision of ISO 5725-1, 5725-2 the estimation of reproducibility and repeatability of measured characteristics determine the design of reflectors and real defects, and thus the reliability of non-destructive testing, including ultrasonic inspection of railways.

Development of Low-cost Wireless Monitoring System and Its Implementation on Computer Numerical Control Machine Tool

“…In addition, this standardization has been utilized in various applications, such as the validation of orthophoto-based impervious surface areas and determination of imperviousness factors, (43) evaluation of the measurement precision of distribution within the lung following intratracheal administration, (44) and ultrasonic testing. (45) Moreover, Suzuki et al proposed an adaptation to the standardization of the statistical design of a measurement precision experiment. (46) D'Aucelli et al developed a MATLAB framework to automate the analysis of the operations of ISO 5725-compliant measuring systems.…”
