Electrical insulating materials - Determination of the effects of ionizing radiation - Part 5: Procedures for assessment of ageing in service

Covers ageing assessment methods which can be applied to components based on polymeric materials (for example, cable insulation and jackets, elastomeric seals, polymeric coatings, gaiters) which are used in environments where they are exposed to radiation. The object of this part of EN 60544 is to provide guidelines on the assessment of ageing in service. The approaches discussed cover ageing assessment programmes based on condition monitoring (CM), the use of equipment deposits in severe environments and sampling of real-time aged components.

Matériaux isolants - Détermination des effets des rayonnements ionisants - Partie 5: Procédures pour l'estimation du vieillissement en service

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 partie de la EN 60544 est de fournir des lignes directrices sur l'évaluation du vieillissement en service. Les approches examinées couvrent les programmes d'évaluation de vieillissement fondés sur le contrôle des conditions (CM), l'utilisation de dépôt d'équipements dans des environnements sévères et l'échantillonnage de composants vieillis en temps réel.

The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)
In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60544-5 has been prepared by subcommittee 15E: Methods oftest, of IEC technical committee 15: Insulating materials.The text of this standard is based on the following documents:FDISReport on voting15E/210/FDIS15E/214/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.IEC 60544 consists of the following parts, under the general title Electrical insulatingmaterials – Determination of the effects of ionizing radiation:Part 1: Radiation interaction and dosimetryPart 2: Procedures for irradiation and testPart 3: (now incorporated into Part 2)Part 4: Classification system for service in radiation environmentsPart 5: Procedures for assessment of ageing in service
