(Main)Measurement of smoke density of cables burning under defined conditions - Part 1: Test apparatus
Measurement of smoke density of cables burning under defined conditions - Part 1: Test apparatus
Provides details of the test apparatus to be used for measuring smoke emission when electric or optical fibre cables are burnt under defined conditions, for example, a few cables burnt horizontally. The light transmittance (lt) under flaming combustion and smouldering conditions can be used as a means of comparing different cables or complying with specific requirements. NOTE: For the purposes of this standard, the term "electric cable" covers all insulated metallic conductor cables used for the conveyance of energy or signals. The principal changes with respect to the previous edition are as follows: a) closer definition of the draught screen and the chamber orifices; b) closer definition of the support for the cable(s) under test; c) removal of minor differences with equivalent CENELEC work to allow parallel voting with that body. Has the status of a group safety publication in accordance with IEC Guide 104.
Mesure de la densité de fumées dégagées par des câbles brûlant dans des conditions définies - Partie 1: Appareillage d'essai
Fournit les détails de l'appareillage d'essai qui doit être utilisé pour la mesure de l'émission de fumées lorsque des câbles électriques ou à fibres optiques brûlent dans des conditions définies, par exemple quelques câbles brûlant horizontalement. La transmittance de la lumière (It) pour des conditions d'essais avec flamme et sans flamme peut être utilisée comme moyen de comparaison entre différents câbles ou pour obéir à des exigences spécifiques. NOTE: Pour les besoins de la présente norme, le terme "câbles électriques" couvre tous les câbles isolés à conducteur métallique utilisés pour la transmission d'énergie ou de signaux. Les principaux changements par rapport à l'édition précédente sont: a) une définition plus précise de l'écran et des orifices; b) une définition plus précise du support pour les câbles essayés; c) la suppression des petites différences par rapport aux travaux du CENELEC pour obtenir un vote parallèle sur le contenu du texte. A le statut de publication groupée de sécurité, conformément au Guide 104 de la CEI.

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.
This consolidated version of IEC 61034-1 consists of the third edition (2005) [documents
20/754/FDIS and 20/766/RVD] and its amendment 1 (2013) [documents 20/1428/FDIS and
20/1443/RVD]. It bears the edition number 3.1.
The technical content is therefore identical to the base edition and its amendment and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendment 1. Additions and deletions are
displayed in red, with deletions being struck through.
– 4 – 61034-1 IEC:2005+A1:2013
International Standard IEC 61034-1 has been prepared by IEC technical committee 20: Electric
cables.
The principal changes with respect to the previous edition are as follows:
a) closer definition of the draught screen and the chamber orifices;
b) closer definition of the support for the cable(s) under test;
c) removal of minor differences with equivalent CENELEC work to allow parallel voting with
that body.
It has the status of a group safety publication in accordance with IEC Guide 104.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
IEC 61034 consists of the following parts, under the general title Measurement of smoke
density of cables burning under defined conditions,
Part 1: Test apparatus
Part 2: Test procedure and requirements
The committee has decided that the contents of the base publication and its amendment will
remain unchanged until the stability 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.
