The International Electrotechnical Commission (IEC) has released IEC 60500:2017 . This includes “Underwater acoustics – Hydrophones – Properties of hydrophones in the frequency range 1 Hz to 500 kHz.” This standard is now available on the IEC webstore.
Description: “IEC 60500:2017 specifies the relevant characteristics and properties of hydrophones in the frequency range 1 Hz to 500 kHz, and specifies how to report these characteristics. Provides guidance on the choice of a hydrophone with appropriate performance for a specific application. This standard is applicable to:
– hydrophones employing piezoelectric sensor elements, designed to respond to sound pressure in water and measure underwater acoustical signals;
– hydrophones with or without an integral pre-amplifier.
This new edition includes the following significant technical changes with respect to the previous edition:
– the format and scope of IEC 60500 have been changed to be compatible with other IEC standards;
– the upper limit of the frequency range of hydrophones has been expanded.”
