Fire hazard testing -
Part 11-2: Test flames - 1 kW pre-mixed flame - Apparatus, confirmatory
test arrangement and guidance
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 corres ponding 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) IEC draws attention to the possibility that the implementation of this document may involve
the use of (a) patent(s). IEC takes no position concerning the evidence, validity or applicability
of any claimed patent rights in respect thereof. As of the date of publication of this document,
IEC [had/had not] received notice of (a) patent(s), which may be required to implement this

document. However, implementers are cautioned that this may not represent the latest
information, which may be obtained from the patent database available at https://patents.iec.ch.
IEC shall not be held responsible for identifying any or all such patent r ights.
IEC 60695-11-2 has been prepared by IEC technical committee 89: Fire hazard testing.
This fourth edition cancels and replaces the third edition published in 2017. This edition
constitutes a technical revision.
It has the status of a basic safety publication in accordance with IEC GUIDE 104 [1] and ISO/IEC
Guide 51 [2].
This edition includes the following significant technical changes with respect to the previous
edition:
a) correction of errors in notes of subclauses 5.2 and 5.3
The text of this International Standard is based on the following documents:

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 of component, circuit,
and product design, as well as the choice of materials, is to reduce to acceptable levels the
potential risks of fire during normal operating conditions, reasonable foreseeable abnormal use,
malfunction, and/or failure. The IEC has developed IEC 60695-1-10 [4] , together with its
companion, IEC 60695-1-11 [5], to provide guidance on how this is to be accomplished.
The primary aims of IEC 60695-1-10 [4] and IEC 60695-1-11 [5] 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 risk assessment.
IEC 60695-11-2 provides a description of the apparatus required to produce a 1 kW test flame,
and provides a description of the principle of a confirmation procedure to check that the effective
power output of the flame is as intended. Guidance on confirmatory tests for test flames is given
in IEC TS 60695-11-40 [3].
This part of IEC 60695 may involve hazardous materials, operations, and equipment. It does
not purport to address all of the safety problems associat
