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.

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).

4 Principles of flame spread
4.1 Liquids
The surface spread of flame over a liquid surface is governed by the flash and fire points of the
liquid. The flash point is the minimum temperature to which the liquid must be heated for the
vapours emitted to ignite momentarily in the presence of a flame under specified test
conditions. In this case, the flash point is measured according to ISO 2592 (Cleveland open
cup).
NOTE Defining the test method is important because the flame spread is described over an open liquid surface,
for which ISO 2592 is applicable. The alternative method of measuring the flash point, described in ISO 2719
(Pensky – Martens closed cup) which is cited in IEC standards for insulating liquids, measures the flash point in a
confined space and is intended to detect minor amounts of volatile material. The flash point measured in this way is
significantly lower than that measured by ISO 2592.
The fire point is the temperature at which the liquid will not only ignite but will continue to burn.
The surface spread of flame rate is determined by gas phase parameters, when the
temperature of the liquid is greater than that of its flash point, and by liquid phase parameters,
when the liquid is at a temperature lower than that of its flash point. Gas phase parameters
include air flow, flame and thermal radiation effects. Liquid phase parameters include
convective fluid motion, surface tension, and liquid viscosity.
4.2 Solids
The surface spread of flame over a solid surface is always associated with air flow, caused by
external factors (wind and ventilation) and by air flows induced by the flame itself. Air flowing in
the opposite direction to that of the surface spread of flame (opposed flow) reduces the surface
spread of flame rate and air flow in the same direction as the surface spread of flame
(wind-aided) enhances the surface spread of flame rate.
For vertical test specimens with ignition at the bottom, the flame moves towards the top and is
defined as the upward surface spread of flame. For vertical test specimens with ignition at the
top, the flame moves towards the bottom, and this behaviour is defined as the downward
surface spread of flame. For horizontal test specimens, the flame moves sideways away from
the area of ignition, and this behaviour is defined as the lateral surface spread of flame.
After ignition of the test specimen, flame propagation will occur if the flame transfers sufficient
heat flux, mostly as thermal radiation, ahead of the pyrolysis front so as to continue pyrolysis
and ignition at a sufficient rate.
The magnitude of the heat flux transferred ahead of the pyrolysis front depends on the heat
release rate of the test specimen, whereas the resistance to ignition is a function of the
minimum ignition temperature of the test specimen and the rate of heating of the surface.
The rate of heating of the surface is, in turn, a function of a number of properties of the test
specimen:
a) thickness;
b) thermal conductivity, (k);
– 12 – 60695-9-1 © IEC:2013
ρ);
c) density, (
d) specific heat capacity, (c).
In a thick test specimen, material below the surface is able to conduct heat away thus reducing
the rate of surface heating and increasing the resistance to ignition. In a thin test specimen this
effect is much reduced and so ignition resistance is lower.
The product, kpc, is known as 'thermal inertia'. If the thermal inertia is high, for example as in
the case of a solid metal, the rate of surface heating will be relatively low and it will therefore
take a relatively long time for the ignition temperature to be reached. If the thermal inertia is
low, for example as in the case of some foamed plastics or low density combustible materials,
the rate of surface heating will be relatively high and it will therefore take a relatively short time
for the ignition temperature to be reached.
Further detailed guidance concerning flame spread on solids is given in ISO/TS 5658-1.
5 Consideration for the selection of test methods
5.1 Fire scenario
The test method(s) selected should be relevant to the fire scenario of concern. Important
parameters to be considered include:
a) the geometry of the test specimen, including the presence of edges, corners or joints;
b) the surface orientation;
c) the direction of flame propagation;
d) the rate and direction of air flow;
e) the nature and position of the ignition source;
f) the magnitude and position of any external heat flux;
g) whether the flammable material is a solid or a liquid.
5.2 Ignition sources
The ignition source used in a laboratory test should be relevant to the fire scenario of concern.
In the case of the fire hazard of electrotechnical equipment, two types of ignition source are of
concern:
a) from unusual localized, internal sources of excessive heat within electrotechnical
equipment and systems;
b) from sources of flame or excessive heat which are external to electrotechnical equipment
and systems.
5.3 Types of test specimen
The test specimen may be a manufactured product, a component of a product, a simulated
product (representative of a portion of a manufactured product), a basic material (solid or
liquid), or a composite of materials.
Variations in the shape, size and arrangement of the test specimen should be limited.
Some test specimens may exhibit anisotropy, for example extruded or moulded thermoplastic
materials. Where the intended usage and installation practice is such that bi-directional spread
of fire presents a fire safety hazard, for instance computer housings, such test specimens
should be tested in both ‘x’ and ‘y’ directions.

60695-9-1 © IEC:2013 – 13 –
NOTE This recommendation does not apply to products typically installed in long, thin configurations, e.g. cables
and conduits.
5.4 Test procedure and apparatus
The test procedure should preferably be designed so that the results can be used for hazard
analysis. However, this may not be necessary in the case of simple tests intended only for
quality control or regulatory purposes.
The test apparatus should be able to test the actual electrotechnical product, a simulated
product, a material or a composite, as described in 5.3.
The test apparatus should be able to impose a heat flux from an external heat source or from a
flame, in an approximately uniform fashion to the test specimen in the region where ignition is
intended to occur.
The test apparatus with imposed heat flux should be able to ignite the vapour-air mixture
emanating from the test specimen. An electrical spark ignitor or a premixed gas-air flame has
been found to be suitable.
Tests for surface spread of flame under well-ventilated conditions should be performed using
an air flow rate which is relevant to the fire scenario of concern.
5.5 Measurement techniques
5.5.1 Direct measurement
The position of the flame front is observed visually. It may be recorded as a function of time or
simply to check some pass/fail distance criterion.
5.5.2 Indirect measurement
Two methods are employed to indirectly assess the rate or amount of flame spread.
One method is to note whether an indicator material has been burned or damaged. Examples
are a paper flag, cotton waste or cotton thread. These indicator materials are positioned at
defined points on or near the test specimen.
The other method is to note the position and/or amount of charred or damaged surface.
Measurements may be made as a function of time or simply to record some pass/fail distance
or area criterion.
It should be noted that direct and indirect methods will not normally give equivalent results.
Limited correlations have been established between results for the rate and extent of surface
spread of flame using these two techniques.
6 Use and interpretation of results
Surface spread of flame depends on the pyrolysis, ignition, and combustion behaviour of a
material. As the heat release rate from a material increases, the surface flame spread over the
surface of a material increases and so does the generation of combustion products. Thus, for a
specific fire, the following all increase together: the surface spread of flame, the heat release
rate, the evolution of combustion products, the fire hazard, and the difficulty in fighting the fire.
By determining the surface spread of flame rate (and associated heat release rate and
generation rates of combustion products), the relative hazard expected in fires of
electrotechnical products is assessed. The assessment is based on the principle that the

slower the surface spread of flame, the lower the expected hazard. It is always desirable that
the surface spread of flame be non-propagating or decelerating.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. A cet effet, la CEI – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de la CEI"). Leur élaboration est confiée à des comités d'études,
aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent également aux
travaux. La CEI collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications
nationales et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications
nationales ou régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de la CEI. La CEI n'est responsable d'aucun des services effectués par les organismes de
certification indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à la CEI, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de la CEI, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de la CEI ou de
toute autre Publication de la CEI, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de la CEI peuvent faire
l’objet de droits de brevet. La CEI ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits
de brevets et de ne pas avoir signalé leur existence.
