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

IEC 60695-1-10:2009 provides general guidance on how to reduce to acceptable levels the risk of fire and the potential effects of fires involving electrotechnical products. It also describes the relationship between fire risk and the potential effects of fire, it also 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 has the status of a horizontal standard in accordance with IEC Guide 104 and ISO/IEC Guide 51.
This publication is to be read in conjunction with  IEC 60695-1-11:2010.

Essais relatif aux risques du feu - Partie 1-10: Lignes directrices pour l'évaluation des risques du feu des produits électrotechniques - Lignes directrices générales

La CEI 60695-1-10:2009 fournit des lignes directrices générales sur la manière de réduire à des niveaux acceptables le risque d'incendie et les effets potentiels des incendies impliquant des produits électrotechniques. Elle décrit la relation entre le risque d'incendie et les effets potentiels des incendies. Elle souligne l'importance de l'approche par scénario pour l'évaluation des dangers du feu et des risques d'incendie. Elle débat également des critères visant à assurer le développement de méthodes d'essai au feu basées sur les dangers qui soient techniquement solides. La présente publication fondamentale de sécurité est destinée aux comités d'études dans le cadre de l'élaboration de normes conformes aux principes exposés dans le Guide CEI 104 et le Guide ISO/CEI 51.
Cette publication doit être lue conjointement avec la CEI 60695-1-11:2010.

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.

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 even in the event of foreseeable abnormal use, malfunction or failure.
This standard, together with its companion, IEC 60695-1-11, provides guidance on how this is
to be accomplished.
The primary aims are 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.
Secondary aims include the minimisation of any flame spread beyond the product’s enclosure
and the minimisation of harmful effects of fire effluents including heat, smoke, and toxic or
corrosive combustion products.
Fires involving electrotechnical products can also be initiated from external non-electrical
sources. Considerations of this nature are dealt with in the overall risk assessment.
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.
