The question of implementation of test samples verification nondestructive testing by comparison them with a set of model test samples each year which are verified using high-sensitivity ultrasonic flaw. Analysis of the result is executed and uncertainty of the longitudinal ultrasonic waves velocity determination is evacuated, which is one of the key indicators in assessing compliance.
measurement uncertainty, the control sample, criterion, conformity, checking’s, velocity of a longitudinal ultrasonic wave
