Ultrasonics - Hydrophones - Part 1: Measurement and characterization of medical ultrasonic fields
IEC 62127-1:2022 specifies methods of use of calibrated hydrophones for the measurement in liquids of acoustic fields generated by ultrasonic medical equipment including bandwidth criteria and calibration frequency range requirements in dependence on the spectral content of the fields to be characterized.This document:- defines a group of acoustic parameters that can be measured on a physically sound basis;- defines a second group of parameters that can be derived under certain assumptions from these measurements, and called derived intensity parameters;- defines a measurement procedure that can be used for the determination of acoustic pressure parameters;- defines the conditions under which the measurements of acoustic parameters can be made using calibrated hydrophones;- defines procedures for correcting for limitations caused by the use of hydrophones with finite bandwidth and finite active element size, and for estimating the corresponding uncertainties.IEC 62127-1:2022 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 and requirements for narrow-band approximation and broadband measurements have been modified; details on waveform deconvolution have been added.d) Procedures for spatial averaging correction have been amended.e) Annex D, Annex E and bibliography have been updated to support the changes of the normative parts.

Ultrasonics - Hydrophones - Part 1: Measurement and characterization of medical ultrasonic fields
IEC 62127-1:2022 specifies methods of use of calibrated hydrophones for the measurement in liquids of acoustic fields generated by ultrasonic medical equipment including bandwidth criteria and calibration frequency range requirements in dependence on the spectral content of the fields to be characterized.
This document:
- defines a group of acoustic parameters that can be measured on a physically sound basis;
- defines a second group of parameters that can be derived under certain assumptions from these measurements, and called derived intensity parameters;
- defines a measurement procedure that can be used for the determination of acoustic pressure parameters;
- defines the conditions under which the measurements of acoustic parameters can be made using calibrated hydrophones;
- defines procedures for correcting for limitations caused by the use of hydrophones with finite bandwidth and finite active element size, and for estimating the corresponding uncertainties.

Ultrasonics - Hydrophones - Part 1: Measurement and characterization of medical ultrasonic fields up to 40 MHz
IEC 62127-1:2007 specifies methods of use of calibrated hydrophones for the measurement in liquids of acoustic fields generated by ultrasonic medical equipment operating in the frequency range up to 40 MHz. The objectives of this standard are: - to define a group of acoustic parameters that can be measured on a physically sound basis; - to define a second group of parameters that can be derived under certain assumptions from these measurements, and called derived intensity parameters; - to define a measurement procedure that may be used for the determination of acoustic pressure parameters; - to define the conditions under which the measurements of acoustic parameters can be made in the frequency range up to 40 MHz using calibrated hydrophones; - and to define procedures for correcting, for limitations caused by the use of hydrophones with finite bandwidth and finite active element size. IEC 62127-1, IEC 62127-2 and IEC 62127-3 are being published simultaneously. Together these cancel and replace IEC 60866:1987, IEC 61101:1991, IEC 61102:1991, IEC 61220:1993 and IEC 62092:2001. The contents of the corrigendum of August 2008 have been included in this copy. The French version of this standard has not been voted upon.
