IEC 60653:1979

Specifies the methods of use of calibrated piezoelectric hydrophones for the measurement in liquids of acoustic fields generated by ultrasonic medical equipment operating in the frequency range 0,5 MHz to 15 MHz.

Defines alternative procedures for the measurement of acoustic pressure and derived intensity parameters for the sound fields generated by single ultrasonic transducers which have cylindrical or spherical active elements and defines additional acoustical terms.

Specifies a method of determining the total radiated acoustic power of ultrasonic transducters based on the use of a radiation force balance. Provides general principles for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured.

Provides a source of reference for the work which has been carried out in order to evaluate the various test procedures for checking the effectiveness of ultrasonic cleaners. Measures the effectiveness of an ultrasonic cleaner under closely defined conditions so that the performance of different makes and models can be compared. Has the status of a technical report.
