General 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 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.
International Standard IEC 60695-9-1 has been prepared by IEC technical committee 89: Fire
hazard testing.
The text of this standard is based on the following documents:
FDIS Report on voting

– Part 9-2: Surface spread of flame – Summary of test methods
The committee has decided that the contents of this publication will remain unchanged until the
stability 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
• reconfirmed,
• withdrawn,

INTRODUCTION
Fires are responsible for creating hazards to life and property as a result of the generation of
heat (thermal hazard), and also toxic effluent, corrosive effluent and smoke (non-thermal
hazard). Fire hazard increases with the burning area leading in some cases to flashover and a
fully developed fire. This is a typical fire scenario in buildings.
The surface spread of flame beyond the area of ignition occurs as a result of the creation of a
pyrolysis front on the surface of the material, ahead of the flame front, arising from the heating
by the flame and external heat sources. The pyrolysis front is the boundary between pyrolysed
material and unpyrolysed material on the surface of the material. Combustible vapours are
generated within the region of pyrolysed material, which mix with air and ignite, creating the
flame front.
The surface spread of flame rate is the distance travelled by the flame front divided by the time
required to travel that distance. The surface spread of flame rate depends on the heat supplied
externally and/or by the flame of the burning material ahead of the burning zone and on the
ease of ignition. The ease of ignition is a function of the minimum ignition temperature,
thickness, density, specific heat, and thermal conductivity of the material. The heat supplied by
the flame depends on the heat release rate, specimen orientation, air flow rate and air flow
direction relative to the surface spread of flame direction. In general, materials show one of the
following types of surface spread of flame behaviour:
a) non-propagation: there is no flame propagation beyond the area of ignition;
b) decelerating propagation: flame propagation stops before reaching the end of the surface of
the material; and
c) propagation: flame propagates beyond the area of ignition and eventually affects the entire
surface of the material.
Properties of the materials that are used to describe the surface spread of flame behaviour are
associated with surface preheating and pyrolysis, generation of vapours, mixing of the vapours
with air, ignition, combustion of the mixture and generation of heat and combustion products.
Flame retardants and surface treatments are used to modify the surface spread of flame
behaviour. Factors that need to be considered for the assessment of the surface spread of
flame behaviour of materials are:
1) the fire scenario (including such parameters as surface orientation, ventilation and the
nature of the ignition source);
2) measurement techniques (see 5.5); and
3) the use and interpretation of results obtained (see 6).
