Fire hazard testing -
Part 1-14: Guidance on the different levels of power and energy related to
the probability of ignition and fire in low voltage electrotechnical products
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) 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 CDV 60695-1-14 Ed.2 © IEC 2025
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 rights.
IEC 60695-1-14 has been prepared by IEC technical committee 89: Fire hazard testing. It is
an International Standard.
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
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.
IEC 60695‑1‑10 [1], IEC 60695‑1‑11 [2] and IEC 60695-1-12 [3] provide guidance on how this
is to be accomplished.
Fires involving electrotechnical products can be initiated from external non-electrical sources.
Considerations of this nature are dealt with in an overall fire hazard (3.1) 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 (3.3) caused by an electrically energised component part and, in the event
of ignition (3.3), to confine any resulting fire within the bounds of the enclosure of the
electrotechnical product;
– minimize 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.
This standard provides guidance to Product Committees on the power levels and amounts of
energy that are likely to cause ignition (3.3) and fire. It also provides guidance to Product
Committees on the fire hazard safeguards (3.2) that might be necessary to protect against the
probability of ignition (3.3).
The probability of fire is highly dependent on the specific fire scenario within the electrotechnical
product itself. Therefore, product committees are ultimately responsible for deciding what fire
hazard safeguards (3.2) are appropriate for their products.
