Ultrasonics - Hydrophones - Part 3: Properties of hydrophones for ultrasonic fields

IEC 62127-3 Ed. 2.1 en:2026

IEC 62127-3:2022+AMD1:2026 CSV specifies relevant hydrophone characteristics. This document 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.

IEC 62127-3:2022 cancels and replaces the first edition published in 2007 and Amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition.

  • a) The upper frequency limit of 40 MHz has been removed.
  • b) Hydrophone sensitivity definitions have been changed to recognize sensitivities as complex-valued quantities.
  • c) Procedures to determine the effective hydrophone size have been changed according to the rationale outlined in Annex B.
  • d) Requirements on the frequencies for which the effective hydrophone size shall be provided have been changed to achieve practicality for increased frequency bands.
  • e) The new Annex B and Annex C have been added.
  • f) Annex A has been updated to reflect the changes of the normative parts.
