A calibration for immersion ultrasonic testing of pipe or tubing should establish atransducer position such as:

Only longitudinal waves are generated in the test piece

I.D. and O.D. notches produce equal responses for equivalent metal path distances

Rayleigh waves are generated through the entire pipe or tubing wall

All ultrasound enters the test piece
