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

The series of International Standards covered by Parts 3-10, 3-21, 3-22, 3-23, 3-24 and 3-25 of IEC 60332 specifies methods of test for the assessment of vertical flame spread of verticallymounted bunched wires or cables, electrical or optical, under defined conditions. 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 may be used to demonstrate the cable's ability to limit flame spread. This part of IEC 60332 covers category A and 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 mm˛ according to the number of test pieces required, and a standard ladder for conductor crosssections 35 mm˛ and smaller. The category is intended for general use where high volumes of non-metallic material are required to be evaluated. A recommended performance requirement is given in annex B.

Preskusi na električnih kablih in kablih iz optičnih vlaken v požarnih razmerah - 3-22. del: Preskus navpičnega širjenja ognja po navpično pritrjenih snopih žic ali kablov - Kategorija A (IEC 60332-3-22:2000 + A1:2008)

Ta serija mednarodnega standarda, zajeta v 3-10., 3-21., 3-22. 3-23., 3-24. in 3-25. delu IEC 60332, določa preskusne metode za ocenjevanje navpičnega širjenja ognja po navpično pritrjenih snopih žic ali kablov, električnih ali optičnih, pod določenimi pogoji. Preskus je namenjen homologacijskemu preskušanju.  Zahteve za preskušanje izbranih kablov so podane v Dodatku A. Širjenje ognja se meri kot obseg škode na vzorcu kablov.  Ta postopek se lahko uporablja za prikaz zmožnosti kabla, da omeji širjenje ognja. Ta del IEC 60332 zajema kategorijo A in se nanaša na kable, nameščena na preskusno lestev, za doseganje nominalnega skupnega volumna nekovinskega materiala 7 l/m preskusnega vzorca. Čas namestitve ognja je 40 min. Pri metodi pritrditve se uporablja sprednja stran lestve, pri čemer se uporablja standardna ali široka lestev za kable, katerih prerez vodnika presega 35 mm v skladu z številom zahtevanih preskušancev, ali standardna lestev pri prerezih vodnika 35 mm in manj. Kjer se zahteva ocenjevanje velikih volumnov nekovinskih materialov, je kategorija namenjena splošni uporabi.   Priporočena zahteva za zmogljivost je podana v Dodatku B.

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 60332-3-22 has been prepared by IEC technical committee 20:
Electric cables.
It has the status of a group safety publication in accordance with IEC Guide 104.
IEC 60332-3-22 forms one of a series of publications dealing with tests on electric cables
under fire conditions; the series supersedes IEC 60332-3 published in 1992. The parts of the
series are described in the introduction.
All pre-existing categories of test are retained and updated. A new category (category D) has
been added to cater for testing at very low non-metallic volumes.

This consolidated version of IEC 60332-3-22 consists of the first edition (2000) [documents
20/404/FDIS and 20/428/RVD] and its amendment 1 (2008) [documents 20/934/CDV and
20/983A/RVC].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 1.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
Annex A forms an integral part of this standard.
Annex B is for information only.
The committee has decided that the contents of the base publication and its amendments 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.

INTRODUCTION
Parts 1 and 2 of IEC 60332 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 parts 1 and 2, 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 ignit
