Tests on electric and optical fibre cables under fire conditions - Part 3-24: Test for vertical flame spread of vertically-mounted bunched wires or cables - Category C (IEC 60332-3-24:2018)

This part of IEC 60332 covers category C for methods of test for the assessment of vertical
flame spread of vertically mounted bunched wires or cables, electrical or optical, under
defined conditions.
This document relates to cables installed on the test ladder to achieve a nominal total volume
of non-metallic material of 1,5 l/m of test sample. The flame application time is 20 min. The
method of mounting uses the front of the standard ladder. The category is intended for
general use where low volumes of non-metallic material are required to be evaluated.
The test is intended for type approval testing. The requirements for the selection of cables for
testing are given in Annex A. The flame spread is measured as the extent of damage of the
cable sample. This procedure can be used to demonstrate the cable’s ability to limit flame
spread.
A recommended performance requirement is given in Annex B.
NOTE For the purposes of this document the term "electric wire or cable" covers all insulated metallic conductor
cables used for the conveyance of energy or signals.

NEW!IEC 60332-3-24:2018 est disponible sous forme de IEC 60332-3-24:2018 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L’IEC 60332-3-24:2018 couvre la catégorie C pour les méthodes d'essai pour l'évaluation de la propagation verticale de la flamme des fils ou câbles électriques ou optiques, disposés en nappes en position verticale, dans des conditions définie. Le présent document concerne les câbles montés sur l'échelle d'essai afin d’obtenir un volume total nominal de matériau non métallique de 1,5 l/m d'échantillon d'essai. La durée d'application de la flamme est de 20 min. La méthode de montage utilise la face avant de l'échelle standard. Cette catégorie est prévue pour une utilisation générale lorsqu’il est requis d'évaluer le comportement de volumes faibles de matériau non métallique. L'essai est prévu pour les essais d'acceptation de type. Les exigences pour la sélection des câbles pour l'acceptation de type sont données à l'Annexe A. La propagation de la flamme est mesurée comme étant l'étendue de la partie endommagée de l'échantillon de câble. Cette procédure peut être utilisée pour démontrer l’aptitude du câble à limiter la propagation de la flamme. L’Annexe B donne une recommandation pour l'exigence de performance. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) des ajustements ont été apportés au titre, et ailleurs, afin de souligner que la Norme s’applique aux câbles à fibre optique, ainsi qu’aux types de conducteurs métalliques;
b) les détails sur la manière dont les câbles sont montés sur l'échelle ont été mieux définis afin d'améliorer la répétabilité et la reproductibilité.

TESTS ON ELECTRIC AND OPTICAL FIBRE CABLES
UNDER FIRE CONDITIONS –
Part 3-24: Test for vertical flame spread of
vertically-mounted bunched wires or cables – Category C
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 60332-3-24 has been prepared by IEC technical committee 20: Electric cables.
This second edition cancels and replaces the first edition published in 2000 and Amendment 1:2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) adjustments have been made to the title, and elsewhere, to emphasise the standard is applicable to optical fibre cables as well as metallic conductor types; b) details of the way in which cables are mounted on the ladder have been better defined in order to improve repeatability and reproducibility.

INTRODUCTION IEC 60332-3-24 is part of a series of publications dealing with tests on electric and optical fibre cables under fire conditions. The IEC 60332-1 and IEC 60332-2 series specify methods of test for flame spread characteristics for a single vertical insulated wire or cable. It cannot be assumed that, because a cable or wire meets the requirements of the IEC 60332-1 and IEC 60332-2 series, a vertical bunch of similar cables or wires will behave in a similar manner. This is because flame spread along a vertical bunch of cables depends on a number of features, such as a) the volume of combustible material exposed to the fire and to any flame which may be produced by the combustion of the cabl
