FIRE HAZARD TESTING –

Part 1-10: Guidance for assessing the fire hazard of
electrotechnical products – General guidelines

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 60695-1-10:2016  IEC 2016 – 5 –
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 equipment design, as well as the choice of materials, is to reduce the risk of fire to a
tolerable level even in the event of reasonably foreseeable (mis)use, malfunction or failure.
This standard, together with its companions, IEC 60695-1-11 and IEC 60695-1-12, provides
guidance on how this is to be accomplished.
The use of compartments with fire-resistant boundaries, and the use of detection and
suppression systems are important methods for the mitigation of fire risk, but are not dealt
with in this standard. Fires involving electrotechnical products can be initiated from external
non-electrical sources. Considerations of this nature are dealt with in an overall fire hazard
assessment.
The aim of the IEC 60695 series of standards is to save lives and property by reducing the
number of fires or reducing the consequences of the fire. This can be accomplished by:
• trying to prevent ignition caused by an electrically energised component part and, in the
event of ignition, to confine any resulting fire within the bounds of the enclosure of the
electrotechnical product;
• trying to minimise flame spread beyond the product’s enclosure and to minimise the
harmful effects of fire effluents including heat, smoke, and toxic or corrosive combustion
products.
Assessing the fire hazard of electrotechnical products is accomplished by performing fire
hazard tests. These tests are divided into two fundamental groups: qualitative fire tests and
quantitative fire tests.
Fire testing of electrotechnical products should, whenever possible, be carried out using
quantitative fire tests having the following characteristics.
a) The test should take into account the circumstances of product use, i.e. contemplated
end-use conditions as well as foreseeable abnormal use. This is because fire conditions
that may be hazardous under one set of circumstances will not necessarily pose the same
threat under a different set.
b) It should be possible to correlate the test results with the harmful effects of fire effluents
referred to above, i.e. the thermal and airborne threats to people and/or property in the
relevant end-use situation. This avoids the creation of artificial, and sometimes distorted,
performance scales with no clear relationship to fire safety.
c) Recognizing that there are usually multiple contributions to the effects of real fires, the
test results should be expressed in well-defined terms and using rational scientific units,
so that the product's contribution to the overall fire effects can be quantitatively assessed
and compared with that of other products’ contributions.
Although quantitative tests are preferred, the characteristics of qualitative fire tests are that
they provide pass/fail and classification results. Under certain circumstances it will be
appropriate to maintain such qualitative test methods or to develop new ones. This part of
IEC 60695-1 establishes the circumstances under which such maintenance or development is
appropriate.

FIRE HAZARD TESTING –

Part 1-10: Guidance for assessing the fire hazard of
electrotechnical products – General guidelines



1 Scope
This part of IEC 60695-1 provides general guidance with respect to fire hazard testing on how
to reduce to a tolerable level the risk of fire and the potential effects of fires involving
electrotechnical products. It also serves as a signpost standard to the other guidance
publications in the IEC 60695 series.
It does not give guidance on the use of fire-resistant compartment boundaries or on the use of
detection and suppression systems for the mitigation of fire risk.
It describes the relationship between fire risk and the potential effects of fire, and provides
guidance to IEC product committees on the applicability of qualitative and quantitative fire
tests to the fire hazard assessment of electrotechnical products. Details of the calculation of
fire risk are not included in the scope of this document.
It emphasises the importance of the scenario approach to fire hazard and risk assessment
and discusses criteria intended to ensure the development of technically sound hazard-based
fire test methods.
It discusses the different types of fire tests, in particular the nature of qualitative and
quantitative fire tests. It also describes the circumstances under which it is appropriate for
IEC product committees to maintain or develop qualitative fire tests.
This standard is intended as guidance to IEC committees, and is to be used with respect to
their individual applications.
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.
