Evaluation and qualification of electrical insulation systems

IEC 60505:2011 establishes the basis for estimating the ageing of electrical insulation systems (EIS) under conditions of either electrical, thermal, mechanical, environmental stresses or combinations of these (multifactor stresses). It specifies the principles and procedures that shall be followed, during the development of EIS functional test and evaluation procedures, to establish the estimated service life for a specific EIS. This standard should be used by all IEC technical committees responsible for equipment having an EIS. The main change with respect to the previous edition is that Annex A: Glossary is now available in an Internet version as well as a hardcopy version. The internet version contains an abridged text version and a multimedia supplement.

Bewertung und Kennzeichnung von elektrischen Isoliersystemen

Evaluation et qualification des systèmes d'isolation électrique

La CEI 60505:2011 établit les bases de l'estimation du vieillissement des systèmes d'isolation électrique (SIE) dans des conditions de contraintes électriques, thermiques, mécaniques, environnementales ou de combinaisons de ces contraintes (contraintes multifactorielles). Elle spécifie les principes et les procédures qui doivent être suivis, au cours du développement d'essais fonctionnels ou de procédures d'évaluation des SIE, pour établir la durée de vie estimée d'un SIE spécifique. Il convient que tous les comités d'études de la CEI responsables de matériels ayant un SIE utilisent la présente norme. La principale modification par rapport à l'édition précédente est que l'Annexe A: Glossaire, est désormais disponible en version internet ainsi qu'en version imprimée. Cette version internet consiste en une version textuelle abrégée et un complément multimédia.

Vrednotenje in kvalificiranje električnih izolacijskih sistemov

Ta mednarodni standard vzpostavlja osnovo za ocenjevanje staranja električnih izolacijskih sistemov (EIA) pod pogoji električnega, toplotnega, mehanskega ali okoljskega stresa ali kombinacije navedenih (večfaktorski stresi) dejavnikov. Določa načela in postopke, ki se morajo upoštevati med razvojem postopkov funkcijskega preskušanja in vrednotenja EIS, da se oceni življenjska doba določenega EIS. Ta standard morajo uporabljati vsi tehnični odbori IEC, odgovorni za opremo, ki vsebuje EIS.

This European Standard was approved by CENELEC on 2011-08-15. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
