Abstract
This article discusses the features of ultrasonic testing technology in accordance with the standard GOST ISO 11666, which provides various methods of sensitivity adjustment and a stepwise assessment of defect admissibility based on its amplitude and conditional length. Examples of quantitative differences in search sensitivity levels depending on the adjustment method as well as experimental confirmation of their influence on testing results are given. To prevent the risk of non-reproducibility in testing results, it is proposed to limit the choice of sensitivity adjustment methods. In addition, the value of the conditional length should be taken into account when developing ultrasonic testing procedures
