IEC 60695-11-4:2011

Fire hazard testing - Part 11-4: Test flames - 50 W flame - Apparatus and confirmational test method

IEC 60695-11-4:2011 provides a description of the apparatus required to produce a 50 W test flame and a description of a calibration procedure to check that the test flame produced meets given requirements. Guidance on confirmatory tests for test flames is given in IEC 60695-11-40. This first edition of IEC 60695-11-4 cancels and replaces the second edition of technical specification IEC/TS 60695-11-4 published in 2004. It constitutes a technical revision. The main changes with respect to the previous edition are the integration of minor editorial and technical changes throughout the text.
This publication is to be read in conjunction with IEC 60695-11-4:2011.

Essais relatifs aux risques du feu - Partie 11-4: Flamme d'essai - Flammes de 50 W - Appareillage et méthodes d'essai de vérification

La CEI 60695-11-4:2011 donne les exigences détaillées pour la production d'une flamme d'essai de 50 W (valeur nominale), de type à pré mélange, d'une hauteur totale de 20 mm approximativement. Des détails sont donnés four la confirmation de la flamme d'essai. Des informations sur la confirmation d'une flamme d'essai figurent dans la CEI 60695-11-40. Cette première édition de la CEI 60695-11-4 annule et remplace la seconde édition de la Spécification Technique CEI/TS 60695-11-4 publiée en 2004. Elle constitue une révision technique. Par rapport à la précédente édition, le principal changement est l'intégration de modifications éditoriales et techniques mineures dans tout le texte.
Cette publication doit être lue conjointement avec la IEC 60695-11-4:2011.

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 60695-11-4 has been prepared by IEC technical committee 89: Fire
hazard testing.
This first edition of IEC 60695-11-4 cancels and replaces the second edition of technical
specification IEC/TS 60695-11-4 published in 2004. It constitutes a technical revision and now
has the status of an International Standard.
It has the status of a basic safety publication in accordance with IEC Guide 104 and ISO/IEC
Guide 51.
The main changes with respect to the previous edition are the integration of minor editorial and
technical changes throughout the text.
