Probabilistic models of substantiation of rejection values of the measured characteristics of defects during ultrasonic testing of welded joints using phased antenna arrays that reduce possible test errors are considered. It is shown that the most important for usage are the reliability indicators of non-destructive testing, taking into account the sub-rejection. The recommended application areas for evaluating the reliability D* criteria of ultrasonic testing using alternative and quantitative indicators for selecting rejection values of measured defect characteristics have been determined.
