Protective devices against diagnostic medical X-radiation - Part 2: Translucent protective plates

This part of IEC 61331 applies to TRANSLUCENT PROTECTIVE PLATES used for RADIATION
PROTECTION in X-ray diagnosis and in X-ray therapy. It also applies to TRANSLUCENT
PROTECTIVE PLATES used for protection against GAMMA RADIATION in nuclear medicine and
BRACHYTHERAPY with automatically-controlled AFTERLOADING equipment.
It does not cover other translucent RADIATION PROTECTION materials, e.g.
− leaded glasses or goggles for protection of the OPERATOR'S eyes (eye spectacles),
− leaded face shields, which cover the entire face of the OPERATOR,
− PATIENT eye protection, and
− thyroid/neck PROTECTIVE DEVICES.
This Part 2 deals with the requirements on
− geometrical accuracy;
− optical quality of the material;
− spectral TRANSMITTANCE;
− radiation ATTENUATION properties;
− marking;
− statement of compliance with this standard.

Dispositifs de protection radiologique contre les rayonnements X pour diagnostic médical - Partie 2: Plaques translucides de protection radiologique

L'IEC 61331-2:2014 s'applique aux plaques translucides de protection radiologique utilisées pour la radioprotection dans le cadre du diagnostic médical et de la radiothérapie par rayonnement X. Elle s'applique également aux plaques translucides de protection radiologique utilisées pour la protection contre le rayonnement gamma en médecine nucléaire et en curiethérapie avec des appareils de projection de sources à contrôles automatiques. Elle ne couvre pas d'autres matériaux translucides de radioprotection, par exemple:
- les verres ou lunettes protectrices au plomb pour les yeux des opérateurs (lunettes oculaires);
- les écrans au plomb couvrant tout le visage de l'operateur;
- les protections pour les yeux du patient; et
- les dispositifs de protection radiologique pour la thyroïde ou le cou. La présente Partie 2 traite des exigences relatives:
- à la précision géométrique;
- à la qualité optique du matériau;
- au facteur de transmission spectrale;
- aux propriétés d'atténuation du rayonnement;
- au marquage; et
- à la déclaration de conformité à la présente norme. Cette deuxième édition annule et remplace la première édition de l'IEC 61331-2, parue en 1994. Elle constitue une révision technique. Cette deuxième édition a été adaptée pour s'appliquer à la technologie actuelle. Les principales modifications et extensions sont les suivantes:
- extension du domaine d'application pour couvrir tous les types de plaques translucides de protection radiologique et tous les types de qualités de rayonnement et de rayonnement gamma;
- suppression de la définition et des exigences pour les plaques translucides de protection radiologique en imagerie visuelle;
- modification des exigences concernant la précision géométrique et la qualité optique;
- modification des exigences concernant la détermination de L'équivalent plomb et de l'épaisseur minimale; et
- modification des exigences concernant les informations et le marquage.

PROTECTIVE DEVICES AGAINST
DIAGNOSTIC MEDICAL X-RADIATION –

Part 2: Translucent protective plates

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 this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61331-2 has been prepared by subcommittee 62B: Diagnostic
imaging equipment, of IEC technical committee 62: Electrical equipment in medical practice.
This second edition cancels and replaces the first edition of IEC 61331-2, published in 1994.
It constitutes a technical revision. This second edition has been adapted to apply to the
present technology.
The essential changes and extensions are:
extension of scope to cover all kinds of TRANSLUCENT PROTECTIVE PLATES and all kinds of
RADIATION QUALITIES and GAMMA RADIATION;
removal of definition and requirements for TRANSLUCENT PROTECTIVE PLATES for visual imaging;
changes of requirements concerning geometrical accuracy and optical quality;
changes of requirements concerning determination of LEAD EQUIVALENT and minimal thickness;
