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

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 external non-electrical
sources. Considerations of this nature should be 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 describes a glow-wire flammability index (GWFI) test method for materials,
and IEC 60695-2-13 describes a glow-wire ignition temperature (GWIT) test method for
materials.
This standard is used to assess the reaction of end products to heat caused by contact with
an electrically heated wire under controlled laboratory conditions. This may be useful for the
evaluation of end products that may be exposed to excess thermal stress such as a fault
current flowing through a wire, overloading of components, and/or poor electrical connections.
It should not be used to solely describe or appraise the fire hazard or fire risk of products, or
assemblies under actual fire conditions. However, results of this test may be used as
elements of a fire hazard assessment which takes into account all of the factors which are
pertinent to a particular end use.
This international standard may involve hazardous materials, operations, and equipment. It
does not purport to address all of the safety problems associated with its use. It is the
responsibility of the user of this international standard to establish appropriate safety and
health practices and determine the applicability of regulatory limitations prior to use.

FIRE HAZARD TESTING –
Part 2-11: Glowing/hot-wire based test methods –
Glow-wire flammability test method for end-products (GWEPT)

1 Scope
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 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.

4 Test specimens
4.1 General
It is not necessary to test end products or parts of end products which have insignificant
mass. Additionally, this test method is not suitable for testing small parts (see 4.4).
4.2 Complete end product
It is preferred that the test specimen should be a complete end product as opposed to a
partial end product (see 4.3). The test specimen shall be chosen so that the conditions of the
test will not be significantly different from those occurring in normal use with regard to shape,
ventilation, effect of thermal stresses, and eventually, the effects of burning or glowing
particles falling from the test specimen.
4.3 Partial end product (alternative)
If the test cannot be made on a complete end product then, unless otherwise specified by the
relevant product standard, it is acceptable to

60695-2-11 © IEC:2014 – 9 –
a) cut a piece containing the part under examination from a complete and assembled end
product, or
b) cut an aperture in the complete end product to allow the glow-wire access, or
c) remove the part under examination in its entirety and test it separately.
Technical committees should define in their relevant product standards what may be removed
to achieve access. So far as possible, these product standards should strive to replicate
actual service locations and conditions.
4.4 Test considerations and limitations associated with the specimen configuration
When cutting an opening for access purposes, a small aperture may affect the results by
leading to the ignition of the surroundings and/or reducing the temperature of the tip of the
glow-wire. The opening should be large enough to supply an adequate supply of air for
combustion.
If, during the test, any part of the equipment containing the test specimen is ignited by
extraneous heat from the glow-wire which in turn influences the thermal conditions at the test
specimen, the test shall be invalid.
The glow-wire flammability test method for end products shall not be used for testing small
parts. This is because such parts cannot be effectively supported to avoid heat losses (see
IEC 60695-2-10), and they are not able to accommodate the penetration of the glow-wire.
The following are considered to be small parts:
a) where each surface lies completely within a circle of 15 mm in diameter; or
b) where it is not possible to fit a circle of 8 mm in diameter completely on at least one of the
surfaces while, at least one part dimension is > 15 mm.
See Figure 1.
When checking a surface,
a) projections on the surface are disregarded and
b) holes or recesses which are not greater than 2 mm in any dimension are disregarded.

5 Test apparatus
The test apparatus is specified in IEC 60695-2-10.
To evaluate the possibility of the spread of fire, for example by burning or glowing particles
falling from the test specimen, a specified layer as described in IEC 60695-2-10, or the
material or components normally surrounding or situated underneath the test specimen, are
placed underneath the test specimen. The distance between the test specimen and the
specified layer representing the surrounding material or components, shall be equal to that
which occurs in end use. If the test specimen is a component such that surrounding materials
and distances are unknown, then the wrapping tissue / wooden board specified layer
described in IEC 60695-2-10 shall be placed 200 mm ± 5 mm below the glow wire point of
contact.
If the test specimen is a complete free-standing equipment, it is placed in its normal position
of use on the specified layer as described in IEC 60695-2-10extending for at least 100 mm
outside the base of the equipment in all directions.
If the test specimen is a complete wall-mounted equipment, it is fixed in its normal position of
use 200 mm ± 5 mm above the specified layer as described in IEC 60695-2-10.
6 Verification of the temperature measuring system
The method of verification of the temperature measuring system is specified in
IEC 60695-2-10.
7 Conditioning
7.1 Conditioning of test specimens
Unless otherwise specified in the relevant product standard, the test specimens shall be
conditioned for 24 h in an atmosphere having a temperature between 15 °C and 35 °C and a
relative humidity between 45 % and 75 %.
7.2 Conditioning of specified layers
If the wrapping tissue / wooden board specified layer is used, the conditioning shall be carried
out according to IEC 60695-2-10. If the material or components normally surrounding or
situated underneath the test specimen is used, the material or components shall be
conditioned in the same way as the test specimen (see 7.1).
7.3 Testing conditions
The test specimens shall be tested in a laboratory atmosphere having a temperature between
15 °C and 35 °C and a relative humidity less than or equal to 75 %. Testing shall be
completed within 30 minutes after the specimen is removed from the conditions specified in
7.1.
8 Test procedure
8.1 General
In addition to the common test procedure specified in IEC 60695-2-10, if not otherwise
specified, the test specimen shall be so arranged that the tip of the glow-wire is applied to the
part of the surface of the test specimen which is likely to be subjected to thermal stresses in
normal use. The glow-wire shall be maintained as close to the horizontal as is practicable.

60695-2-11 © IEC:2014 – 11 –
In cases where the test shall be made at more than one point on the same test specimen,
care shall be taken that any deterioration caused by previous tests will not affect the result of
the test to be made.
In cases where the areas subjected to thermal stresses during normal use of the equipment
are not specified in detail, the tip of the glow-wire is applied at a place where the section is
thinnest, but if possible not less than 15 mm from the upper edge of the test specimen.
Clamping the test specimen onto the test apparatus shall not introduce excessive internal
mechanical stresses in the test specimen during the test.
8.2 Test temperatures
The glow-wire is heated to the test temperature specified in the relevant product standard.
This temperature should preferably be one of the temperatures shown in Table 1.

When selecting test temperatures, product committees should consider Figure A.1 which
gives suggested glow-wire end product test (GWEPT) temperatures.
8.3 Number of test specimens
If not otherwise specified by the relevant product standard, the test is made on one test
specimen.
9 Observations and measurements
During the time of application of the glow-wire, t (30 s ± 1 s), and during a further period of
A
30 s, the test specimen, the parts surrounding the test specimen and the specified layer
placed below it shall be observed and the following shall be reported:
a) whether there is no ignition; or, if there is ignition, the duration, t (to the nearest 0,5 s),
i
from the beginning of tip application up to the time at which the test specimen or the
specified layer placed below it ignites;
b) the duration, t , (to the nearest 0,5 s) from the beginning of tip application up to the time
E
when all flames extinguish, during or after the period of application;
c) whether the test specimen extinguishes by virtue of most of the flaming material being
withdrawn with the glow-wire;
d) whether the test specimen is totally burned; and

– 12 – 60695-2-11 © IEC:2014
e) whether there is any ignition of the specified layer placed underneath the test specimen.
10 Evaluation of test results
The test specimen is considered to have a GWEPT of T if at a test temperature of T °C,
a) there is no ignition, or
b) all of the following situations apply when ignition has occurred:
i) if flames or glowing combustion of the test specimen extinguish within 30 s after
removal of the glow wire, i.e. t ≤ t + 30 s; and
E A
ii) the specified layer placed underneath the test specimen does not ignite.

h) the relevant part(s) or zone(s) of the product subjected to the test on the same test
specimen (see 8.1);
i) whether the criteria specified are sufficient to check compliance with the safety
requirements, or whether other criteria , should be used (see Clause 9); and
j) whether consequential testing needs to be considered to cover residual risks and, if so,
which test method and what requirements should be specified.
NOTE See IEC 60695-1-11 for additional guidance on consequential testing.

GWEPT = Glow Wire End Product Test
NOTE 1 A separate Fire Hazard Assessment (FHA) as determined by the relevant product standard will dictate
the appropriate GWEPT temperature.
NOTE 2 The phrases “insufficient energy” and “close proximity” should be defined by the relevant product
committee. It is dependent upon a number of factors (for example: the severity of the hazard).
NOTE 3 Examples of installation equipment include socket outlets, circuit protection devices, and LV switchgear.
NOTE 4 The right side of the flow chart (Installation equipment = no) is intended to partially represent the limited
application of the GWEPT as currently used by IEC 60335-1. Refer to that document for other considerations.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a
pour objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les
domaines de l'électricité et de l'électronique. A cet effet, la CEI – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de la CEI"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent
également aux travaux. La CEI collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI ne peut pas être tenue responsable
de l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications
nationales et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications
nationales ou régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de la CEI. La CEI n'est responsable d'aucun des services effectués par les organismes de
certification indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
