Tests on electric and optical fibre cables under fire conditions - Part 3-22: Test for vertical flame spread of vertically-mounted bunched wires or cables - Category A (IEC 60332-3-22:2018)

This part of IEC 60332 covers category A 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 7 l/m of test sample. The flame application time is 40 min. The
method of mounting uses the front of the ladder, a standard or wide ladder being used for
cables having a conductor cross-section greater than 35 mm2 according to the number of test
pieces required, and a standard ladder for conductor cross-sections 35 mm2 and smaller. The
category is intended for general use where high 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.

L’IEC 60332-3-22:2018 couvre la catégorie A 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 7 l/m d'échantillon d'essai. La durée d'application de la flamme est de 40 min. La méthode de montage utilise la face avant de l'échelle, celle-ci étant du type standard ou du type large pour les câbles dont au moins un conducteur est de section supérieure à 35 mm2 selon le nombre d'éprouvettes exigé, et du type standard pour les câbles dont tous les conducteurs sont de sections inférieures ou égales à 35 mm2. Cette catégorie est prévue pour une utilisation générale lorsqu’il est requis d'évaluer le comportement de volumes élevés 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 deuxième édition annule et remplace la première édition parue en 2000 et l'Amendement 1:2008. Cette édition constitue une révision technique. 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.

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 60332-3-22 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 60332-3-22 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 cables;
b) the geometrical configuration of the cables and their relationship to an enclosure;
c) the temperature at which it is possible to ignite the gases emitted from the cables;
d) the quantity of combustible gas released from the cables for a given temperature rise;
e) the volume of air passing through the cable installation;
f) the co
