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;
- hydrophones with or without an associated pre-amplifier;
This International Standard specifies relevant hydrophone characteristics.
Associated standards deal with hydrophone calibration (IEC 62127-2) and their use characterizing ultrasonic fields (IEC 62127-1), including comprehensive lists of references.
