This International Standard is applicable to ultrasonic equipment designed for physiotherapy
consisting of an ultrasonic transducer generating continuous or quasi-continuous wave ultrasonic energy in the frequency range 0,5 MHz to 5 MHz.
This standard only relates to ultrasonic physiotherapy equipment employing a single plane
unfocused circular transducer per treatment head, producing static beams perpendicular to
the face of the treatment head in accordance with present practice.
This standard specifies:
. methods of measurement and characterization of the output of ultrasonic physiotherapy equipment based on reference testing methods;
. characteristics to be specified by manufacturers of ultrasonic physiotherapy equipment based on reference testing methods;
. guidelines for safety of the ultrasonic field generated by ultrasonic physiotherapy equipment;
. methods of measurement and characterization of the output of ultrasonic
physiotherapy equipment based on routine testing methods;
. acceptance criteria for aspects of the output of ultrasonic physiotherapy equipment based on routine testing methods.
Therapeutic value and methods of use of ultrasonic physiotherapy equipment are not covered by the scope of this standard.
