IEC 60811-406:2012

Electric and optical fibre cables - Test methods for non-metallic materials - Part 406: Miscellaneous tests - Resistance to stress cracking of polyethylene and polypropylene compounds

IEC 60811-406:2012 gives the procedure for evaluating the resistance to stress cracking of polyethylene and polypropylene compounds which are typically used for communication and optical fibre cables. IEC 60811-406:2012 cancels and replaces Clause 8 of IEC 60811-4-1:2004, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100:2012.
This publication is to be read in conjunction with IEC 60811-100:2012.

Câbles électriques et à fibres optiques - Méthodes d'essai pour les matériaux non-métalliques - Partie 406: Essais divers - Résistance des mélanges polyéthylène et polypropylène aux craquelures

La CEI 60811-406:2012 décrit la procédure à suivre pour évaluer la résistance des mélanges polyéthylène et polypropylène aux craquelures. Ces mélanges sont généralement utilisés pour les câbles de communication et les câbles à fibres optiques. La CEI 60811-406:2012 annule et remplace l'Article 8 de la CEI 60811-4-1:2004, qui est supprimée. L'ensemble des informations relatives aux remplacements figure dans l'Annexe A de la CEI 60811-100:2012. Aucune modification technique n'a été effectuée par rapport à l'édition précédente; voir cependant l'avant-propos de la CEI 60811-100:2012.
Cette publication doit être lue conjointement avec la CEI 60811-100:2012.

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 60811-406 has been prepared by IEC technical committee 20:
Electric cables.
This Part 406 of IEC 60811 cancels and replaces Clause 8 of IEC 60811-4-1:2004, which is
withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012.
There are no specific technical changes with respect to the previous edition, but see the
