Electric cables - Tests on extruded oversheaths with a special protective function

Provides a range of tests which may be required for electric cables which have an extruded oversheath and where that oversheath performs a special protective function. The standard covers cables for use in insulated systems and in uninsulated systems. The tests are categorized for use as routine tests, type tests and tests after installation. These tests comprise of electrical routine tests on cable oversheath used in insulated or uninsulated systems, abrasion and corrosion spread type tests, electrical test on cable oversheath after installation. Routine tests and tests after installation, as specified in the relevant cable standards, are applicable for all situations. Type tests depend upon the nature of the system and the construction of the cable and do not have to be carried out for normal conditions of use. The significant technical changes with respect to the previous edition are as follows: - The text has been modified in order to consider the function of the oversheath, irrespective of the way the metallic sheath or screen of the cable is earthed because, in some cases, the oversheath is designed to act not only as a protection against corrosion, but also to reduce the risk of degradation of the cable insulation system. This requirement may be independent of the nature of the insulation and independent of the rated voltage of the cable. - More precise wording has been introduced regarding the application of some tests (if the sheaths or foils are bonded to the oversheath or not). - The test requirements have been revised in order to be in line with the standards published after the second edition. - The pressure test at high temperature has been deleted as the requirement is specified in the relevant cable standards. - A "Guidance on tests after installation" (Annex B) has been included.

Câbles électriques - Essais sur les gaines extérieures extrudées avec fonction spéciale de protection

Fournit une gamme d'essais que l'on peut demander pour les câbles électriques qui comportent une gaine extrudée, quand cette gaine remplit une fonction spéciale de protection. Cette norme s'applique aux câbles destinés aux réseaux à écran isolé et aux réseaux à écran non isolé. Les essais sont classés en tant qu'essais individuels, essais de type et essais après pose. Ces essais comprennent: - des essais diélectriques individuels pour les gaines des câbles utilisés dans les réseaux à écran isolé ou non isolé, - des essais de type d'abrasion, et de diffusion de la corrosion, - un essai diélectrique de gaine après pose. Les essais individuels et les essais après pose, tels que spécifiés dans les normes particulières de câbles, sont applicables en toute circonstance. Les essais de type dépendent de la nature du réseau et de la structure du câble et n'ont pas à être effectués pour des conditions normales d'utilisation. Les modifications techniques majeures, par rapport à la précédente édition, sont les suivantes: - Le texte a été modifié pour prendre en compte la fonction de la gaine extérieure, indépendamment du type de mise à la terre de la gaine ou l'écran métallique du câble, parce que, dans certains cas, la gaine extérieure est conçue non seulement pour assurer une protection contre la corrosion, mais aussi pour réduire le risque de dégradation de l'isolation du câble. Cette exigence peut être indépendante de la nature de l'enveloppe isolante et indépendante de la tension assignée du câble. - La rédaction concernant la pertinence de certains essais a été précisée (selon que les gaines ou feuilles sont contrecollées ou non à la gaine extérieure). - Les exigences d'essai ont été revues pour être en accord avec les spécifications publiées postérieurement à la deuxième édition. - L'essai de pression à température élevée a été supprimé, car cette exigence est spécifiée dans les spécifications particulières des câbles. - Des " Recommandations pour les essais après pose " (Annexe B) ont été introduites.

TESTS ON EXTRUDED OVERSHEATHS
WITH A SPECIAL PROTECTIVE FUNCTION

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 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 60229 has been prepared by IEC technical committee 20: Electric
cables.
This third edition cancels and replaces the second edition published in 1982 and constitutes a
technical revision.
The significant technical changes with respect to the previous edition are as follows:
– The text has been modified in order to consider the function of the oversheath,
irrespective of the way the metallic sheath or screen of the cable is earthed because, in
some cases, the oversheath is designed to act not only as a protection against corrosion,
but also to reduce the risk of degradation of the cable insulation system. This requirement
may be independent of the nature of the insulation and independent of the rated voltage of
the cable.
– More precise wording has been introduced regarding the application of some tests (if the
sheaths or foils are bonded to the oversheath or not).
– The test requirements have been revised in order to be in line with the standards
published after the second edition.

– 4 – 60229 © IEC:2007
– The pressure test at high temperature has been deleted as the requirement is specified in
the relevant cable standards.
– A “Guidance on tests after installation” (Annex B) has been included.
The text of this standard is based on the following documents:
FDIS Report on voting
20/901/FDIS 20/908/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

ELECTRIC CABLES –
TESTS ON EXTRUDED OVERSHEATHS
WITH A SPECIAL PROTECTIVE FUNCTION

1 Scope
This International Standard provides a range of tests which may be required for electric
cables which have an extruded oversheath and where that oversheath performs a special
protective function.
NOTE 1 The need for the special functions may be independent of the nature of the insulation type or
independent of the rated voltage of the cable.
The standard covers cables for use in insulated systems and in uninsulated systems.
The tests are categorized for use as
a) routine tests,
b) type tests,
c) tests after installation.
These tests comprise:
− electrical routine tests on cable oversheath used in insulated or uninsulated systems,
− abrasion and corrosion spread type tests,
− electrical test on cable oversheath after installation.
Routine tests and tests after installation, as specified in the relevant cable standards, are
applicable for all situations.
Type tests depend upon the nature of the system and the construction of the cable and do not
have to be carried out for normal conditions of use.
The application of the abrasion test is given in Annex A.
NOTE 2 Guidance on tests after installation is given in Annex B.
