scope:

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.
