Electrical insulating materials - Thermal endurance properties -- Part 3: Instructions for calculating thermal endurance characteristics

This part of IEC 60216 specifies the calculation procedures to be used for deriving thermal endurance characteristics from experimental data obtained in accordance with the instructions of IEC 60216-1 and IEC 60216-2, using fixed ageing temperatures and variable ageing times. The experimental data may be obtained using non-destructive, destructive or proof tests. Data obtained from non-destructive or proof tests may be incomplete, in that measurement of times taken to reach the endpoint may have been terminated at some point after the median time but before all specimens have reached end-point. The procedures are illustrated by worked examples, and suitable computer programs are recommended to facilitate the calculations.

Matériaux isolants électriques - Propriétés d'endurance thermique -- Partie 3: Instructions pour le calcul des caractéristiques d'endurance thermique

La CEI 60216-3:2006 spécifie les méthodes de calcul à utiliser pour obtenir les caractéristiques d'endurance thermique à partir des données expérimentales obtenues conformément aux instructions de la CEI 60216-1 et de la CEI 60216-2, en utilisant des températures de vieillissement fixes et des temps de vieillissement variables. Les données expérimentales peuvent être obtenues en utilisant des essais non destructifs, des essais destructifs et des essais d'épreuve. Les données obtenues à partir d'essais non destructifs ou d'essais d'épreuve peuvent être incomplètes, car la mesure des temps mis pour atteindre le point limite peut avoir été arrêtée à un moment situé après le temps médian, mais avant que toutes les éprouvettes n'aient atteint le point limite. Les méthodes sont illustrées par des exemples pratiques, et des programmes informatiques adaptés sont recommandés pour faciliter les calculs. Les modifications majeures par rapport à la première édition concernent la mise à jour du Tableau C.2. De plus, le domaine d'application a été élargi pour couvrir une plus grande gamme de caractéristiques de données, en particulier en ce qui concerne les données incomplètes, comme cela est souvent le cas pour les données obtenues à partir de critères d'essai d'épreuve. Il convient que cette plus grande souplesse d'utilisation conduise à un emploi plus efficace du temps disponible pour les essais de vieillissement. Enfin, les méthodes spécifiées dans cette partie de la CEI 60216 ont été largement soumises aux essais et ont été utilisées pour calculer les résultats à partir d'un grand nombre de données expérimentales obtenues conformément aux autres parties de la norme. L'Annexe E "Programme informatique" a été complètement remaniée.

This European Standard was approved by CENELEC on 2006-06-01. 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, 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, Spain,
Sweden, Switzerland and the United Kingdom.

EN 60216-3:2006 - 2 -
The text of document 112/26/FDIS, future edition 2 of IEC 60216-3, prepared by IEC TC 112, Evaluation
and qualification of electrical insulating materials and systems, was submitted to the IEC-CENELEC
parallel vote and was approved by CENELEC as EN 60216-3 on 2006-06-01.
This European Standard supersedes EN 60216-3:2002.
The major technical changes with regard to EN 60216-3:2002 concern an updating of Table C.2. In
addition, the scope has been extended to cover a greater range of data characteristics, particularly with
regard to incomplete data, as often obtained from proof test criteria. The greater flexibility of use should
lead to more efficient employment of the time available for ageing purposes. Finally, the procedures
specified in this part of EN 60216 have been extensively tested and have been used to calculate results
from a large body of experimental data obtained in accordance with other parts of the standard. Annex E
'Computer program' has been completely reworked.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-03-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-06-01
Annex ZA has been added by CENELEC.
Endorsement notice
The text of the International Standard IEC 60216-3:2006 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following note has to be added for the standard indicated:
IEC 60216-5 NOTE  Harmonized as EN 60216-5:2003 (not modified).
