Electrical insulating materials - Determination of the effects of ionizing radiation - Part 5: Procedures for assessment of ageing in service
IEC 60544-5:2011 covers ageing assessment methods which can be applied to components based on polymeric materials (e.g. cable insulation and jackets, elastomeric seals, polymeric coatings, gaiters) which are used in environments where they are exposed to radiation. The object of this standard is aimed at providing methods for the assessment of ageing in service. The approaches discussed in the following clauses cover ageing assessment programmes based on condition monitoring (CM), the use of sample deposits in severe environments and sampling of real-time aged components. This second edition cancels and replaces the first edition, published in 2003, and constitutes an editorial revision to align it with standards recently developed by SC 45A as well as with other parts in the IEC 60544 series.

La CEI 60544-5:2011 couvre les méthodes d'évaluation du vieillissement pouvant être appliquées aux composants à base de matériaux polymères (par exemple, des gaines et isolations de câble, des joints en élastomère, des revêtements polymères, des gaines) qui sont utilisés dans des environnements où ils sont exposés aux rayonnements. L'objet de la présente norme est destiné à fournir des méthodes d'évaluation du vieillissement en service. Les approches examinées dans les articles qui suivent couvrent les programmes d'évaluation de vieillissement fondés sur le contrôle des conditions (CM), l'utilisation de dépôt d'échantillons dans des environnements sévères et l'échantillonnage de composants vieillis en temps réel. Cette deuxième édition annule et remplace la première édition, publiée en 2003, dont elle constitue une éditoriale révisée destinée à aligner ce document avec des normes récemment élaborées au sein du SC 45A, ainsi qu'avec d'autres parites de la série CEI 60544.
Električni izolacijski materiali - Ugotavljanje učinkov ionizirnega sevanja - 5. del: Postopki za ocenjevanje staranja med uporabo
Ta del standarda IEC 60544 zajema metode za ocenjevanje staranja, ki jih je mogoče uporabiti za dele na osnovi polimernih materialov (npr. izolacija in plašči kablov, elastomerna tesnila, polimerne prevleke, gamaše), ki se uporabljajo v okoljih, kjer so izpostavljeni sevanju. Namen tega standarda je zagotoviti metode za ocenjevanje staranja med uporabo. Pristopi, obravnavani v naslednjih točkah, zajemajo programe za ocenjevanje staranja na podlagi spremljanja stanja (CM), puščanja vzorcev v neugodnih okoljih in vzorčenje delov, staranih v realnem času.

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
