Abstract
A reference block for determining the characteristics of individual ultrasonic transducers contained within right circular cylinder type ultrasonic probes. Right circular cylinder type ultrasonic probes are designed for performing ultrasonic inspections of components that can only be examined from within a center line access hole. The reference block is made from the same material as that of the right circular cylinder type components which will be examined using the ultrasonic probe being characterized and is designed with curved contact surfaces that specifically duplicate the surfaces of those components. This reference block can be used to calibrate instruments prior to contact inspection using angle-beam search units. The reference block is also useful for checking the performance of both angle-beam and straight-beam search units and for evaluating instrument performance.
