International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 61674:2013
Title Medical electrical equipment - Dosimeters with ionization chambers and/or semiconductor detectors as used in X-ray diagnostic imaging
Project Number 23242
Abstract/Scope 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.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
