Title
Ultrasonics – Power measurement – Radiation force balances and performance requirements

Ultrasons – Mesurage de puissance – Balances de forces de rayonnement et exigences de fonctionnement

International Electrotechnical Commission

Publication Date:
Dec 1, 2006

Scope:

This International Standard

• specifies a method of determining the total emitted 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 (target) intercepts the sound field to be measured;

• establishes limitations of the radiation force method related to cavitation and temperature rise;

• establishes quantitative limitations of the radiation force method in relation to diverging and 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 force balance 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 force balance in the frequency range 0,75 MHz to 5 MHz;

• the measurement of total ultrasonic power of transducers, preferably with well-collimated beams;

• 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.
