Specifies a method of determining the total radiated acoustic power of ultrasonic transducers based on the use of a radiation force balance. Establishes general principles for the use of radiation force balances in which an obstacle intercepts the sound field to be measured. Applicable to: the measurement of ultrasonic power based on the use of a radiation force balance in the frequency range from 0,5 MHz to 25 MHz; the measurement of total ultrasonic power of transducers with well-collimated beams; the use of radiation force balances of the gravimetric type.
