適用范圍：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.
