IEC 61161:1992/AMD1:1998

Contains an 'experimental' standard defining an ultrasonic cleaning exposure test designed to determine the ability of components and equipment to withstand the effects of ultrasonic cleaning. Has the status of a technical report.

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.
