Insulating materials - Industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes - Part 2: Methods of test

This part of IEC 61212 describes methods of test for the materials defined in IEC 61212-1. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.

Matériaux isolants - Tubes et barres industriels, rigides, ronds, stratifiés, à base de résines thermodurcissables, à usages électriques - Partie 2: Méthodes d'essai

La CEI 61212-2:2006 décrit les méthodes d'essai des matériaux définis dans la CEI 61212-1. Les matériaux qui sont conformes à cette spécification satisfont à des niveaux de performances établis. Cependant, il convient que le choix d'un matériau par un utilisateur et pour une application particulière soit fondé sur les exigences réelles nécessaires pour obtenir les performances satisfaisantes pour cette application, et non pas fondé sur cette seule spécification. Les principales modifications suivantes ont été apportées par rapport à l'édition précédente: ajout d'instructions liées à l'utilisation et à la sécurité de l'application. Le document a été reformaté pour tenir compte du format en cours des documents CEI. Les références à la méthode d'essai ont été mises à jour.

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
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of it
