Annotation of standard text IEC 60544-5-ed.3.0 :

IEC 60544-5:2022 is available as IEC 60544-5:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60544-5:2022 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 document is aimed at providing methods for the assessment of ageing in service. The approaches discussed in Clause 5 through Clause 9 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 edition includes the following significant technical changes with respect to the previous edition: - added recent references in 7.4 showing that some electrical condition monitoring methods show promising correlations with ageing; - updated recommendations for implementation of a sample deposit in 9.2, installation of a sample deposit in 9.3 and testing of samples from the deposit in 9.4; - updated list of references. IEC 60544-5:2022 est disponible sous forme de IEC 60544-5:2022 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente. LIEC 60544-5:2022 traite des methodes devaluation du vieillissement qui peuvent etre appliquees aux composants a base de materiaux polymeres (gaines et isolations de cable, joints en elastomere, revetements polymeres, garnitures) qui sont utilises dans des environnements ou ils sont exposes aux rayonnements. Lobjet du present document est de fournir des methodes pour evaluer le vieillissement en service des materiaux. Les approches examinees dans les Articles 5 a 9 concernent les programmes devaluation de vieillissement fondes sur une surveillance de letat (CM, Condition Monitoring), lutilisation de depots dechantillons dans des environnements severes et lechantillonnage de composants vieillis en temps reel. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - des references recentes ont ete ajoutees en 7.4 afin dintroduire des methodes de surveillance de letat qui montrent des correlations prometteuses vis-a-vis du vieillissement; - les recommandations ont ete mises a jour pour la mise en ouvre dun depot dechantillons en 9.2, linstallation dun depot dechantillons en 9.3 et les essais sur les echantillons du depot en 9.4; - la liste de references a ete mise a jour.
