| Note in Official Journal: | |
| Subject of the standard: | 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. |
