Omfang

IEC 62127-3:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62127-3:2022 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.
