Abstract
An ultrasonic calibration block for standardizing an output of a pulse-echo ultrasonic inspection system is provided with an insonification surface for receiving ultrasonic pulses from the inspection system and a plurality of reflective interfaces stacked on top of one another and positioned at different distances from the insonification surface, each reflective interface having a different and characteristic reflectivity. A method of calibrating the output of the inspection system, using the calibration block, employs standard waveforms generated by insonifying the calibration block to generate a look-up table of standard waveform amplitudes related to a standardized output of the inspection system for a given material of a part to be inspected.
