Electrical insulation systems - Procedures for thermal evaluation - Part 1: General requirements - Low-voltage

Specifies a general test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS) and establishes a procedure that compares the performance of a candidate EIS to that of a reference EIS. This basic standard is applicable to existing or proposed EIS used in electrotechnical products with an input voltage of up to 1 000 V where the thermal factor is the dominating ageing factor. This second edition cancels and replaces the first edition published in 1998, and constitutes a technical revision to make this basic standard compatible with parts 21 and 22.

Elektrische Isoliersysteme - Verfahren zur thermischen Bewertung - Teil 1: Allgemeine Anforderungen - Niederspannung

Systèmes d'isolation électrique - Procédures d'évaluation thermique - Partie 1: Exigences générales - Basse tension

Spécifie une procédure d'essai générale pour une évaluation thermique et une qualification des systèmes d'isolation électriques (SIE), et établit une procédure comparant la qualité de fonctionnement d'un système d'isolation électrique candidat à celle d'un système d'isolation électrique de référence. Cette norme fondamentale s'applique aux systèmes d'isolation électriques existants ou proposés, utilisés dans les produits électrotechniques dont la tension d'entrée monte jusqu'à 1 000 V pour lesquels le facteur thermique est le facteur de vieillissement prépondérant. Cette deuxième édition annule et remplace la première édition, parue en 1998, et constitue une révision technique qui rend la présente norme fondamentale compatible avec les parties 21 et 22.

This European Standard was approved by CENELEC on 2005-02-01. 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, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.
