Fire hazard testing - Part 2-11: Glowing/hot-wire based test methods - Glow-wire flammability test method for end-products (GWEPT)

EN IEC 60695-2-11 specifies a test method on an end product. It is intended to simulate the effects of thermal stresses produced by an electrically heated source to represent a fire hazard. This test method is used to check that, under defined test conditions, an end product exposed to an electrically heated source has either a limited ability to ignite or, if it ignites, a limited ability to propagate flame. However, the fire hazard analysis, the flammability aspects and the flame spreading to other products are not covered by the present standard. This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements, test methods or test conditions of this basic safety publication will not apply unless specifically referred to or included in the relevant publications.

NEW! IEC 60695-2-11:2014 est disponible sous forme de IEC Standards+ 60695-2-11:2014 qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.  IEC 60695-2-11:2014 spécifie une méthode d'essai applicable au  produit fini. Elle est destinée à     simuler l'effet  de contraintes thermiques  produites par une source chauffée électriquement afin de    représenter   un danger d'incendie.  La présente méthode d'essai permet de vérifier que, dans     des conditions  d'essai définies, un  produit fini exposé à   une source  chauffée électriquement présente une aptitude limitée à  s'enflammer ou, s'il s'enflamme, une   aptitude  limitée à propager  la  flamme. Cependant, la présente norme ne traite   pas  de   l'analyse du  danger  d'incendie, des aspects d'inflammabilité   et de propagation de  flammes à d'autres produits.   Cette deuxième édition de la CEI 60695-2-11 annule et remplace la première  édition  de la CEI 60695-2-11 publiée en 2000. Elle constitue une révision technique. Les principales modifications    apportées par rapport à l'édition précédente sont énumérées ci-dessous:  - l'introduction a été modifiée pour fournir le contexte et montrer la relation avec le domaine d'application,  - modification du domaine d'application pour davantage de clarté, et pour faire référence aux publications fondamentales de sécurité,  - ajout à l'Article 2 de nombreux termes et définitions applicables à la présente Norme,  - introduction et clarification de l'application des 'petites pièces' et de la 'masse négligeable',  - clarification supplémentaire à l'Article 4 des différents types d'éprouvettes, de la manière de les spécifier et des limitations de la méthode d'essai,  - clarification à l'Article 5 de la distance par rapport à la  sous-couche spécifiée, lorsqu'elle n'est pas connue,  - transfert des informations de l'Article 6 dans la procédure d'essai de l'Article 8,  - clarification à l'Article 7 du conditionnement de la sous-couche spécifiée et des conditions d'essai ambiantes de laboratoire,  - suppression de la mesure de la hauteur de flamme maximale de l'Article 9,  - introduction de la référence à cet essai comme essai 'GWEPT', et modification du titre en conséquence et  - la révision de l'Annexe A, afin de refléter les pratiques en vigueur au sein des comités de produits clés. Elle a le statut d'une publication fondamentale de sécurité, conformément au Guide CEI 104 et au Guide ISO/CEI 51. Cette norme doit être utilisée conjointement avec la CEI 60695-2-10. Mots-clés: fil incandescent/chauffant, fil incandescent, inflammabilité, risque du feu

Standard EN IEC 60695-2-11 določa preskusno metodo za končni proizvod. Namenjena je poustvarjanju učinkov toplotne preobremenitve, ki jo proizvede električno ogrevani vir, s čimer se ponazori požarna ogroženost. Ta preskusna metoda se uporablja za preverjanje, ali ima pod opredeljenimi preskusnimi pogoji končni proizvod, ki je izpostavljen električno ogrevanem viru, omejeno sposobnost vžiga ali, če se vžge, omejeno sposobnost širjenja plamena. Vendar pa v tem standardu niso zajeti analiza požarne ogroženosti, vidiki vnetljivosti in širjenje plamena na druge proizvode. Ta osnovna varnostna publikacija je namenjena tehničnim odborom za pripravo standardov v skladu z načeli vodil IEC 104 in ISO/IEC 51. Ena od odgovornosti tehničnega odbora je, da kjer je to primerno, uporablja osnovne varnostne publikacije. Zahteve, preskusne metode ali preskusni pogoji iz te osnovne varnostne publikacije se ne uporabljajo, razen če so izrecno navedeni ali zajeti v ustrezne publikacije.

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.

INTRODUCTION
The purpose of this Introduction is to provide background regarding the basic guidance that
prompted the preparation of this International Standard and how it relates to the Scope.
In the design of any electrotechnical product, the risk of fire and the potential hazards
associated with fire need to be considered. In this respect the objective within the design of
component, circuit, and product design, as well as the choice of the materials, is to reduce to
acceptable levels the potential risks of fire during normal operating conditions, reasonable
foreseeable abnormal use, malfunction, and/or failure. IEC Technical Committee 89 has
developed IEC 60695-1-10, together with its companion, IEC 60695-1-11, to provide guidance
on how this is to be accomplished.
The primary aims of IEC 60695-1-10 and IEC 60695-1-11 are to provide guidance on how:
a) to prevent ignition caused by an electrically energized component part, and
b) to confine any resulting fire within the bounds of the enclosure of the electrotechnical
product in the event of ignition.
Secondary aims of these documents include the minimization of any flame spread beyond the
product’s enclosure and the minimization of harmful effects of fire effluents such as heat,
smoke, toxicity and/or corrosivity.
Fires involving electrotechnical products can also be initiated from
