EN IEC 60522-1:2021

Medical electrical equipment - Diagnostic X-rays - Part 1: Determination of quality equivalent filtration and permanent filtration

IEC 60522-1:2020 applies to X-RAY TUBE ASSEMBLIES and to FILTERING MATERIAL, in medical diagnostic applications up to a HIGH VOLTAGE of 150 kV. For HIGH VOLTAGES greater than 50 kV, this document applies to X-RAY TUBE ASSEMBLIES with tungsten or tungsten-alloy TARGETS only. IEC 60522-1:2021 defines the concept of PERMANENT FILTRATION of X-RAY TUBE ASSEMBLIES, and it defines the term FILTERING MATERIAL. Methods are given to determine the PERMANENT FILTRATION of an X-RAY TUBE ASSEMBLY and for determining the QUALITY EQUIVALENT FILTRATION of FILTERING MATERIALS. It contains requirements for statements of compliance of X-RAY TUBE ASSEMBLIES in ACCOMPANYING DOCUMENTS and for markings on X-RAY TUBE ASSEMBLIES, and for indications and statements of compliance of FILTERING MATERIAL. IEC 60522-1:2020 cancels and replaces the second edition of IEC 60522 published in 1999. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the IEC 60522:1999: The scope of the IEC 60522-1 has been changed with respect to second edition of the IEC 60522 as follows: a) As radiotherapy standards do not reference IEC 60522, radiotherapy is no longer in the scope. Consequently, the HIGH VOLTAGE is limited to 150 kV, and copper is no longer used as reference material. b) While IEC 60522:1999 covers only PERMANENT FILTRATION, IEC 60522-1 also covers quite generally “material filtering the X-RAY BEAM incident on the PATIENT”. This concerns materials like ADDED FILTERS, table-tops, a breast COMPRESSION DEVICE, and materials in the BEAM LIMITING DEVICE. For these materials the defined term FILTERING MATERIAL has been introduced. c) In order to provide technical and scientific background and rationale on the content of IEC 60522-1, IEC TR 60522-2 was introduced.

L'IEC 60522-1:2020 s’applique aux GAINES EQUIPEES et au MATERIAU DE FILTRAGE, dans les applications de diagnostic médical soumises à une HAUTE TENSION maximale de 150 kV. Pour les HAUTES TENSIONS supérieures à 50 kV, le présent document s’applique aux GAINES EQUIPEES avec CIBLES en tungstène ou en alliage de tungstène uniquement. L'IEC 60522-1:2020 définit le concept de FILTRATION PERMANENTE des GAINES EQUIPEES ainsi que le terme MATERIAU DE FILTRAGE. Des méthodes sont données pour déterminer la FILTRATION PERMANENTE d’UNE GAINE EQUIPEE ainsi que la FILTRATION DE QUALITE EQUIVALENTE des MATERIAUX DE FILTRAGE. Il comprend des exigences relatives aux déclarations de conformité des GAINES EQUIPEES dans les DOCUMENTS D’ACCOMPAGNEMENT et aux marquages sur les GAINES EQUIPEES, ainsi qu’aux indications et déclarations de conformité du MATERIAU DE FILTRAGE. L'IEC 60522-1:2020 annule et remplace la seconde édition de l’IEC 60522 parue en 1999. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’IEC 60522:1999. Le domaine d’application de l’IEC 60522-1 a été modifié par rapport à la deuxième édition de l’IEC 60522 comme suit: a) Les normes de radiothérapie ne faisant pas référence à l’IEC 60522, la radiothérapie ne fait plus partie du domaine d’application. Par conséquent, la HAUTE TENSION est limitée à 150 kV et le cuivre n’est plus utilisé comme matériau de référence. b) Alors que l’IEC 60522:1999 traite uniquement de la FILTRATION PERMANENTE, l’IEC 60522 1 traite également de façon plus générale du "matériau filtrant le FAISCEAU DE RAYONNEMENT X incident sur le PATIENT". Ceci concerne des matériaux tels que des FILTRES ADDITIONNELS, des plateaux de table, un DISPOSITIF DE COMPRESSION du sein et des matériaux présents dans le LIMITEUR DE FAISCEAU. Le terme défini de MATERIAU DE FILTRAGE est employé pour désigner ces matériaux. c) L’IEC TR 60522-2 a été ajouté afin de fournir un contexte et une justification techniques et scientifiques sur le contenu de l’IEC 60522-1.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of
