This International Standard is applicable to
· hydrophones employing piezoelectric sensor elements, designed to measure the pulsed and continuous-wave ultrasonic fields generated by ultrasonic equipment;
· hydrophones used for measurements made in water and in the frequency range between 15 MHz and 40 MHz;
· hydrophones with or without an integral amplifier;
· hydrophones with a circular piezoelectrically active element.
This International Standard specifies
· relevant hydrophone characteristics;
· methods of determining directional response and hydrophone sensitivity based on relative or comparative measurements;
and describes
· absolute hydrophone calibration methods.
Recommendations and references to accepted literature are made for the various relative and absolute calibration methods in the frequency range covered by this International Standard.
