Fire hazard testing - Part 2-11: Glowing/hot-wire based test methods - Glow-wire flammability test method for end products (GWEPT) (IEC 60695-2-11:2021)
This part of IEC 60695 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 this document.
This basic safety publication focusing on safety test method(s) is primarily intended for use by
technical committees in the preparation of safety publications 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.

L'IEC 60695-2-11:2021 spécifie une méthode d’essai applicable au produit fini. Elle est destinée à simuler les effets des 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, le présent document ne traite pas de l’analyse du danger d'incendie, des aspects d’inflammabilité et de propagation de flammes à d’autres produits. La présente publication fondamentale de sécurité, fondée sur la ou les méthodes d'essai de sécurité, est essentiellement destinée à être utilisée par les comités d’études dans le cadre de l’élaboration de publications de sécurité conformément aux principes établis dans le Guide IEC 104 et le Guide ISO/IEC 51. L’une des responsabilités d’un comité d’études consiste, le cas échéant, à utiliser les publications fondamentales de sécurité dans le cadre de l’élaboration de ses publications. Cette norme doit être utilisée conjointement avec l’IEC 60695-2-10. Cette troisième édition annule et remplace la deuxième édition parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) ajout à l’Article 3 de nombreux termes et définitions applicables au présent document.

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.
IEC 60695-2-11 has been prepared by IEC technical committee 89: Fire hazard testing. It is an
International Standard.
This third edition cancels and replaces the second edition published in 2014. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Numerous terms and definitions relevant to this document have been added to Clause 3.

INTRODUCTION
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
1
foreseeable abnormal use, malfunction, and/or failure. IEC 60695-1-10 [1] , together with its
companion IEC 60695-1-11 [2], has been developed 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 to:
a) prevent ignition caused by an electrically energized component part, and
b) confine any resulting fire within the bounds of the enclosure of the electrotechnical product
in the event of ignition.
Secondary aims of IEC 60695-1-10 and IEC 60695-1-11 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 external non-electrical
sources. Considerations of this nature are normally dealt with in the overall fire hazard
assessment.
In electrotechnical equipment, overheated metal parts can act as ignition sources. In glow-wire
tests, a glowing wire is used to simulate such an ignition source.
IEC 60695-2-10 describes a glow-wire test apparatus and common test procedure, IEC 60695-
2-12 [3] describes a glow-wire flammability index (GWFI) test method for materials, and
IEC 60695-2-13 [4] describes a glow-wire ignition tempera
