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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 60695-1-30 has been prepared by IEC technical committee 89:
Fire hazard testing.
This second edition cancels and replaces the first edition of IEC 60695-1-30, published in
2002, and constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
– Further explanation given in the introduction and scope.
– Clause 3: changes to the definitions.
– Clause 4: clarifications of the principles of product design considering preselection.
– Clause 5: clarifications of the advantages and limitations of preselection.
– Clause 6: clarifications of the aspects of preselection relative to hazard assessment.

– 4 – 60695-1-30 © IEC:2008
– Annex A: changes in the references for examples of test methods which may be relevant
to preselection.
– Annex B: changes in the illustrative example of the flowchart of the use of preselection
tests for resistance to fire hazards of a specific product type.
It has the status of a basic safety publication in accordance with IEC Guide 104 and
ISO/IEC Guide 51.
The text of this standard is based on the following documents:
FDIS Report on voting
89/865/FDIS 89/869/RVD

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This publication is to be used in conjunction with the future IEC 60695-1-10 and IEC 60695-
1-11 .
A list of all parts in the IEC 60695 series, under the general title Fire hazard testing, can be
found on the IEC website.
Part 1 consists of the following sub-parts:
Part 1-10 : Guidance for assessing the fire hazard of electrotechnical products –
General guidelines
Part 1-11 : Guidance for assessing the fire hazard of electrotechnical products –

The committee has decided that the contents of this publication will remain unchanged until

the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the
data related to the specific publication. At this date, the publication will be

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 to acceptable levels the
potential risks of fire even in the event of foreseeable abnormal use, malfunction or failure.
The future IEC 60695-1-10 and IEC 60695-1-11 provide guidance on how this is to be
accomplished using quantitative and qualitative fire tests.
The information gained from properly designed small-scale tests can be used as an aid for the
preselection of proper materials, parts, components or sub-assemblies with regard to the fire
hazard evaluation of
