适用范围：This International Standard• specifies a method of determining the total emitted acoustic power of ultrasonictransducers based on the use of a radiation force balance;• establishes general principles for the use of radiation force balances in which an obstacle(target) intercepts the sound field to be measured;• establishes limitations of the radiation force method related to cavitation and temperaturerise;• establishes quantitative limitations of the radiation force method in relation to divergingand focused beams;• provides information on assessment of overall measurement uncertainties.This International Standard is applicable to:• the measurement of ultrasonic power up to 1 W based on the use of a radiation forcebalance in the frequency range from 0,5 MHz to 25 MHz;• the measurement of ultrasonic power up to 20 W based on the use of a radiation forcebalance in the frequency range 0,75 MHz to 5 MHz;• the measurement of total ultrasonic power of transducers, preferably with well-collimatedbeams;• the use of radiation force balances of the gravimetric type or force feedback type.NOTE The titles of all publications referred to in this Standard are listed in the Bibliography.
