La CEI 62465:2010 fournit des stratégies, des exigences techniques et des pratiques recommandées pour la gestion du vieillissement normal des systèmes de câbles qui sont importants pour la sûreté en centrale nucléaire. Les exigences principales sont présentées dans le corps de la norme qui est suivi d'un certain nombre d'annexes informatives présentant des exemples de techniques, de procédures et de matériels pour l'essai des câbles qui sont disponibles pour garantir à l'industrie nucléaire que les dégradations liées au vieillissement n'impactent pas la sûreté des installations. Cette publication indique qu'elle contient des couleurs qui sont considérées comme utiles à une bonne compréhension de son contenu.
Jedrske elektrarne - Merilna in nadzorna oprema za zagotavljanje varnosti - Upravljanje staranja električnih kablov (IEC 62465:2010)
Ta mednarodni standard vsebuje strategije, tehnične zahteve in priporočene prakse za upravljanje normalnega staranja kablov, ki so pomembni za varnost v jedrskih elektrarnah. Glavne zahteve so predstavljene v osnovnem besedilu tega mednarodnega standarda, sledijo pa mu številne informativne priloge s primeri tehnik, postopkov in opreme za preskušanje kablov, ki se uporabljajo v jedrski industriji, da se zagotovi, da staranje kablov ne vpliva na varnost elektrarne.
Ta mednarodni standard zajema kable in njihove dodatke (npr. konektorje), nameščene v jedrskih elektrarnah (znotraj in zunaj nadzora). Podaja zahteve za preskušanje kablov med predvidenim vzdrževanjem, odpravljanjem napak, upravljanjem staranja in zagotavljanjem varnosti elektrarne. Uporablja se za kable merilne in nadzorne opreme, signalne kable in napajalne kable z napetostjo manj kot 1 kV. Natančneje, ta mednarodni standard se osredotoča na tehnike preskušanja na mestu uporabe, s katerimi se prepoznava težave v kabelskih vodnikih (tj. bakrene žice) in v manjši meri na izolacijskem materialu (tj. polimeri). Sledi standardu IEC 62342 o »upravljanju staranja«, v katerem so podane splošne smernice za upravljanje staranja merilnih in nadzornih komponent v jedrskih elektrarnah, vključno s kabli. Poudariti je treba, da se tehnologije za preskušanje kablov razvijajo, tako da so na voljo tudi nove metode, ki niso zajete v tem mednarodnem standardu. Natančneje, ta mednarodni standard zajema tipične metode preskušanja kablov, ki so se uporabljale v jedrski industriji v zadnjem desetletju.
Pomembno je tudi poudariti, da ena sama tehnika preskušanja kablov verjetno ne more zagotoviti dokončnih rezultatov, ampak je za zanesljivo diagnozo običajno potrebna kombinacija več tehnik.

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
