The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with

EN 62127-1:2007/A1:2013(Amendment)
Ultrasonics - Hydrophones - Part 1: Measurement and characterization of medical ultrasonic fields up to 40 MHz
SIST EN 62127-1:2008/A1:2014

This part of IEC 62127 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;
– to define procedures for correcting, for limitations caused by the use of hydrophones with finite bandwidth and finite active element size.
NOTE 1 Throughout this standard, SI units are used. In the specification of certain parameters, such as beam areas and intensities, it may be convenient to use decimal multiples or submultiples. For example beam area may be specified in cm2 and intensities in W/cm2 or mW/cm2.
NOTE 2 The hydrophone as defined may be of a piezoelectric or an optic type. The introduction however implies that optical hydrophones are not covered.

Ultrasonics - Hydrophones - Part 2: Calibration for ultrasonic fields up to 40 MHz
SIST EN 62127-2:2008/A1:2014

This part of IEC 62127 specifies: absolute hydrophone calibration methods; relative (comparative) hydrophone calibration methods. Recommendations and references to accepted literature are made for the various relative and absolute calibration methods in the frequency range covered by this standard. This standard is applicable to hydrophones used for measurements made in water and in the ultrasonic frequency range up to 40 MHz; hydrophones employing circular piezoelectric sensor elements, designed to measure the pulsed wave and continuous wave ultrasonic fields generated by ultrasonic equipment; hydrophones with or without a hydrophone pre-amplifier.

Standard means for the reporting of the acoustic output of medical diagnostic ultrasonic equipment
SIST EN 61157:2008/A1:2014

This International Standard is applicable to medical diagnostic ultrasonic equipment.
– It provides a set of traceable acoustic parameters describing the acoustic fields.
– It defines a standard means and format for the reporting of the acoustic output information.
– It also describes a reduced dataset recommended for equipment generating low acoustic output levels.
NOTE The information tabulated in this standard format can be used for
a) exposure planning for biological effects studies;
b) exposure data for prospective epidemiological studies conducted using exposure conditions similar to those reported in this standard. In the absence of actual exposure data for retrospective epidemiological studies, the information tabulated in this standard format might also be used with
cautionary comment.

SIST EN IEC 62220-2-1:2024

IEC 62220-2-1:2023 describes the performance metrics associated with DUAL-ENERGY IMAGING capable DIGITAL X-RAY IMAGING DEVICES meant for medical applications and specifies the methods for their determination. These metrics can be used to analyse TISSUE-SUBTRACTED IMAGES and to evaluate dose performance, noise characteristics, and tissue-subtraction efficacy of DIGITAL X-RAY IMAGING DEVICES. The described methods indicate the procedures to obtain MULTI-SPECTRAL PRIMARY DATA and to compute their derived TISSUE-SUBTRACTED IMAGES. The intended users of this document are MANUFACTURERS and well-equipped test laboratories. This document is restricted to DIGITAL X-RAY IMAGING DEVICES that are used for single or multiple exposure dual-energy radiographic imaging based on, for example, CR systems, direct and indirect flat panel-detector based systems. This document excludes and is not applicable to: – DIGITAL X-RAY IMAGING DEVICES intended to be used in mammography or in dental RADIOGRAPHY; – slot scanning DIGITAL X-RAY IMAGING DEVICES; – COMPUTED TOMOGRAPHY or CONE-BEAM COMPUTED TOMOGRAPHY; – photon-energy discriminating devices such as photon counting X-RAY IMAGING DEVICES; – devices for dynamic imaging (where series of images are acquired, as in fluoroscopy or cardiac imaging). – DIGITAL X-RAY IMAGING DEVICES intended to be used with RADIOTHERAPY beams.

Medical electrical equipment - Dosimetric instruments used for non-invasive measurement of X-ray tube voltage in diagnostic radiology
SIST EN IEC 61676:2023

IEC 61676:2023 is available as IEC 61676:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61676:2023 specifies the performance requirements of instruments as used in the non-invasive measurement of X-RAY tube voltage up to 150 kV and the relevant compliance tests. This document also describes the method for calibration and gives guidance for estimating the uncertainty in measurements performed under conditions different from those during calibration. Applications for such measurement are found in diagnostic radiology including mammography, computed tomography (CT), dental radiology and radioscopy. This document is not concerned with the safety aspect of such instruments. The requirements for electrical safety applying to them are contained in IEC 61010-1. IEC 61676:2023 cancels and replaces first edition published in 2002, Amendment 1:2008. This edition constitutes a technical revision. It includes an assessment of the combined standard uncertainty for the performance of a hypothetical instrument for the non-invasive measurement of the tube high voltage (in Annex A) which replaces Annex A of the edition 1.1 titled "Recommended performance criteria for the invasive divider".
