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 60695-11-5 has been prepared by IEC technical committee 89:
Fire hazard testing.
This second edition cancels and replaces the first edition published in 2004. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The scope has been broadened to allow this test method to also simulate the effects of
small flames from outside the equipment;
b) Propane and butane gas are the specified fuel source with a minimum purity of 95 %;
c) A new concept has been added which allows the burner to be moved during the test to
avoid dripping material from falling onto the tip of the burner tube;
d) The burner tube material is now a referenced source;

IEC 60695-11-5:2016 © IEC 2016 – 5 –
e) The reference for the copper block material has changed – the ISO publication (ISO 1337)
has been withdrawn with no replacement. A new callout is now used;
f) Informative Annex C and a bibliography have been added.
The text of this standard is based on the following documents:
FDIS Report on voting
89/1346/FDIS 89/1351/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
It has the status of a basic safety publication in accordance with IEC Guide 104 and
ISO/IEC Guide 51.
A list of all the parts in the IEC 60695 series, under the general title Fire hazard testing, can
be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website 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.

INTRODUCTION
The best method for testing electrotechnical products with regard to fire hazard is to duplicate
exactly the conditions occurring in practice. In most instances this is not possible.
Accordingly, for practical reasons, the testing of electrotechnical products with regard to fire
hazard is best conducted by simulating as closely as possible the actual effects occurring in
practice.
Parts of electrotechnical equipment might be exposed to excessive thermal stress due to
electric effects. This can result in deterioration that might impair the safety of the equipment.
Such parts should not be unduly affected by heat or by fire generated within the equipment.
Parts of insulating material or of other combustible material which are liable to propagate
flames inside the equipment may be ignited by flames produced by a failing component.
Under certain conditions, for example a fault current flowing over a tracking path, overloading
of components or parts and bad connections, flames may also occur; such flames may
impinge upon combustible parts in the vicinity.
This part of IEC 60695 is intended to be used to measure and describe the properties of
materials, products or assemblies in response to heat and flame under controlled laboratory
conditions and is not intended to be used to describe or appraise the fire hazard or fire risk of
materials, products, or assemblies under actual fire conditions. This 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 standard to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use.

FIRE HAZARD TESTING –
Part 11-5: Test flames – Needle-flame test method –
Apparatus, confirmatory test arrangement and guidance

1 Scope
This part of IEC 60695 specifies a needle-flame test to simulate the effect of a small flame
which may result from fault conditions, in order to assess the fire hazard by a simulation
technique. The 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 an assessment of the fire
hazard of a particular end use.
It is applicable to electrotechnical equipment, its sub-assemblies and components and to solid
electrical insulating materials or other combustible materials.
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.
