IEC 61212-3-1:2013

Insulating materials - Industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes - Part 3: Specifications for individual materials - Sheet 1: Round laminated rolled tubes

IEC 61212-3-1:2013 gives requirements for industrial rigid round laminated rolled tubes for electrical purposes, based on different resins and different reinforcements. Applications and distinguishing properties are given in Table 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. This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Details of test for insulation resistance after immersion in water and values for permissible deviation from nominal external diameter of round rolled tubes in the "as rolled and cured" condition are changed. Key words: industrial rigid round laminated rolled tubes

Matériaux isolants - Tubes et barres industriels rigides, ronds, stratifiés, à base de résines thermodurcissables, à usages électriques - Partie 3: Spécifications pour matériaux particuliers - Feuille 1: Tubes ronds stratifiés enroulés

La CEI 61212-3-1:2013 donne les exigences relatives aux tubes industriels rigides ronds, stratifiés, enroulés, à usages électriques, à base de différentes résines et de différents matériaux de renfort. Les applications et les propriétés distinctives sont données au Tableau 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. Cette troisième édition annule et remplace la deuxième édition parue en 2006. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: Les détails d'essais relatifs à la résistance d'isolement, ainsi que les valeurs d'écart admissible par rapport au diamètre extérieur nominal des tubes ronds enroulés en l'état "enroulé et traité" après immersion dans l'eau ont été modifiés. Mots clès: tubes industriels rigides ronds, stratifiés, enroulés

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61212-3-1 has been prepared by IEC technical committee 15:
Solid electrical insulating materials.
This third edition cancels and replaces the second edition published in 2006. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
Details of test for insulation resistance after immersion in water and values for permissible
deviation from nominal external diameter of round rolled tubes in the “as rolled and cured”
condition are changed.
