Medical diagnostic X-ray equipment - Radiation conditions for use in the determination of characteristics
This International Standard applies to test procedures which, for the determination of characteristics of systems or components of medical diagnostic X-ray equipment, require well-defined radiation conditions. Except for mammography, this standard does not apply to conditions where discontinuities in radiation absorption of elements are deliberately used to modify properties of the radiation beam (for example by rare earth filters). This standard deals with methods for generating radiation beams with radiation conditions which can be used under test conditions typically found in test laboratories or in manufacturing facilities for the determination of characteristics of medical diagnostic X-ray equipment. Examples of such radiation qualities are radiation beams emerging through the filtration from the X-ray source assembly. radiation conditions represent the more general case, where scattered radiation emerges from an exit surface of a patient or a phantom. This requires a well defined geometrical arrangement.

Equipement de diagnostic médical à rayonnement X - Conditions de rayonnement pour utilisation dans la détermination des caractéristiques
La présente Norme internationale est applicable aux procédures d'essais qui, pour la détermination des caractéristiques des systèmes ou des composants des équipements à rayonnement X de diagnostic médical, nécessitent des conditions de rayonnement bien définies. Exception faite de la mammographie, la présente norme n'est pas applicable aux conditions dans lesquelles des discontinuités dans l'absorption des rayonnements sont délibérément utilisées en vue de modifier les propriétés du faisceau de rayonnement (par exemple au moyen de filtres aux terres rares). La présente norme traite des méthodes de génération des faisceaux de rayonnement dans des conditions de rayonnement pouvant être utilisées dans les conditions d'essai généralement rencontrées dans les laboratoires d'essai ou dans les installations de fabrication pour la détermination des caractéristiques des équipements à rayonnement X de diagnostic médical. Des exemples de telles qualités de rayonnement sont les faisceaux de rayonnement provenant de la filtration de l'ensemble radiogène à rayonnement X. Les conditions de rayonnement représentent le cas le plus général, où le rayonnement diffusé provient de la surface de sortie d'un patient ou d'un fantôme. Cela nécessite des conditions géométriques bien définies.

This European Standard was approved by CENELEC on 2005-12-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland

Foreword
The text of document 62C/391/FDIS, future edition 2 of IEC 61267, prepared by SC 62C, Equipment for
radiotherapy, nuclear medicine and radiation dosimetry, of IEC TC 62, Electrical equipment in medical
practice, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61267
on 2005-12-01.
This European Standard supersedes EN 61267:1994.
The main changes compared to EN 61267:1994 include:
a) introduction of “practical peak voltage” for measuring X-ray tube voltage;
b) introduction of a new procedure for establishing the radiation qualities;
c) inserting of an informative Annex B “Determination of the amount of additional filtration” and a
normative Annex C “Measurement of the practical peak voltage”;
d) revision of radiation qualities and radiation conditions;
e) addition of term definitions.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-09-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-12-01
This European Standard makes reference to International Standards. Where the International Standard
referred to has been endorsed as a European Standard or a home-grown European Standard exists, this
European Standard shall be applied instead. Pertinent information can be found on the CENELEC web
site.
In this standard, the following print types are used:
– requirements proper: roman type;
– test specifications: italic type;
– notes and explanatory matter: small roman type;
– TERMS USED THROUGHOUT THIS PARTICULAR STANDARD THAT ARE DEFINED IN CLAUSE 3, OR IN OTHER
STANDARDS: SMALL CAPITALS.

Endorsement notice
The text of the International Standard IEC 61267:2005 was approved by CENELEC as a European
Standard without any modification.
