FIELD: machine building.
SUBSTANCE: proposed method comprises making two independent measurements of absolute depth of every defect and wall full thickness, using obtained results to define means square deviation of measurements, defining the confidence interval for defect absolute depth, and comparing tolerable absolute or relative depth of defect with confidence interval upper limit.
EFFECT: higher reliability and accuracy.
