IEC 62963:2020

Radiation protection instrumentation - X-ray computed tomography (CT) inspection systems of bottled/canned liquids

IEC 62963:2020 describes the technical requirements, test methods, inspection requirements, markings and labelling, and requirements on the accompanying documents, packaging, shipping and storage for X-ray security inspection systems that inspect bottled or canned liquids (hereinafter referred to as "the system") based on X-ray computed tomography (CT). Here, the system is limited to those that feature tomographic scanning, not standard X-ray projection. This document is applicable to liquids, aerosols and gelatinous objects in transparent or visually opaque containers.
This technical performance document includes minimum or baseline performance requirements; regulators may require additional performance testing.

Instrumentation pour la radioprotection - Systèmes d'inspection par tomographie aux rayons x par ordinateur (CT) des liquides en bouteille ou en canette

IEC 62963:2020 décrit les exigences techniques, les méthodes d'essai, les exigences d'inspection, le marquage et l'étiquetage ainsi que les exigences relatives aux documents d'accompagnement, au conditionnement, au transport et au stockage des systèmes d'inspection aux rayons X des liquides en bouteille ou en canette (ci-après dénommés "le système") reposant sur la tomographie par ordinateur. Seuls les systèmes d'imagerie par tomographie sont ici pris en considération, et non les systèmes d'émission normale de rayons X. Le présent document s'applique aux liquides, aux aérosols et aux gels dans des contenants transparents ou visuellement opaques.
Le présent document fixe des exigences de performance minimales ou de référence; les organismes de réglementation peuvent exiger des essais de performance supplémentaires.

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 possibilit
