Intercomparison of ultrasonic power calibration of ultrasonic transducers from 1 to 10 MHz

Objective



The objective of the intercomparison is to compare the ultrasonic power calibration of a number of standard transducers in primary laboratories.

Status:

In view of potential measurement difficulties, it was agreed that the intercomparison should initially be restricted to calibrations of only one of the transducers, namely the 4 MHz one. The results of this initial phase demonstrated that at least one laboratory had to further develop its equipment in order to eliminate possible sources of error. This having been done, the intercomparison is now continuing with the 1, 2, 5 and 10 MHz transducers.
