Medical electrical equipment - Dosimeters with ionization chambers and/or semiconductor detectors as used in X-ray diagnostic imaging
IEC 61674:2024 specifies the performance and some related constructional requirements of DIAGNOSTIC DOSIMETERS intended for the measurement of AIR KERMA, AIR KERMA LENGTH PRODUCT or AIR KERMA RATE, in photon radiation fields used in medical X-ray imaging, such as RADIOGRAPHY, RADIOSCOPY and COMPUTED TOMOGRAPHY (CT), for X-RADIATION with generating potentials in the range of 20 kV to 150 kV. This document is applicable to the performance of DOSIMETERS with VENTED IONIZATION CHAMBERS and/or SEMICONDUCTOR DETECTORS as used in X-ray diagnostic imaging.IEC 61674:2024 cancels and replaces the second edition published in 2012. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) for mammography, the manufacturer specifies the REFERENCE VALUE for the RADIATION QUALITY;b) for mammography, the manufacturer provides the MINIMUM RATED RANGE of RADIATION QUALITIES for the compliance test on energy dependence of response;c) the compliance test for analogue displays was removed;d) the compliance tests for range reset, the effect of leakage and recombination losses were removed. These tests are already covered by the test on linearity and cannot be conducted for modern devices. The estimation of COMBINED STANDARD UNCERTAINTY was changed accordingly;e) the compliance test for mains rechargeable and battery-operated dosimeters were updated for modern devices

Medical electrical equipment - Dosimeters with ionization chambers and/or semiconductor detectors as used in X-ray diagnostic imaging
IEC 61674:2012 specifies the performance and some related constructional requirements of diagnostic dosimeters intended for the measurement of air kerma, air kerma length product or air kerma rate, in photon radiation fields used in radiography, including mammography, radioscopy and computed tomography, for X-radiation with generating potentials not greater than 150 kV. This International Standard is applicable to the performance of dosimeters with vented ionization chambers and/or semiconductor detectors as used in X-ray diagnostic imaging. The object of this standard is to establish requirements for a satisfactory level of performance for diagnostic dosimeters, and to standardize the methods for the determination of compliance with this level of performance. This standard is not concerned with the safety aspects of dosimeters. The diagnostic dosimeters covered by this standard are not intended for use in the patient environment and, therefore, the requirements for electrical safety applying to them are contained in IEC 61010-1. This second edition cancels and replaces the first edition and constitutes a technical revision.
