INTRODUCTION
IEC 60332-3-10 is part of a series of publications dealing with tests on electric and optical
fibre cables under fire conditions.
The IEC 60332-1 and IEC 60332-2 series specify methods of test for flame spread
characteristics for a single vertical insulated wire or cable. It cannot be assumed that,
because a wire or cable meets the requirements of the IEC 60332-1 and IEC 60332-2 series,
a vertical bunch of similar cables or wires will behave in a similar manner. This is because
flame spread along a vertical bunch of cables depends on a number of features, such as
a) the volume of combustible material exposed to the fire and to any flame which may be
produced by the combustion of the cables;
b) the geometrical configuration of the cables and their relationship to an enclosure;
c) the temperature at which it is possible to ignite the gases emitted from the cables;
d) the quantity of combustible gas released from the cables for a given temperature rise;
e) the volume of air passing through the cable installation;
f) the construction of the cable, for example armoured or unarmoured, multi- or single-core.
All of the foregoing assume that the cables are able to be ignited when involved in an
external fire.
The IEC 60332-3 series gives details of a test where a number of cables are bunched
together to form various test sample installations. For easier use and differentiation of
various test categories, the parts are designated as follows:
Part 3-10: Apparatus
Part 3-21: Category A F/R
Part 3-22: Category A
Part 3-23: Category B
Part 3-24: Category C
Part 3-25: Category D
Parts from 3-21 onwards define the various categories and the relevant procedures. The
categories are distinguished by test duration, the volume of non-metallic material of the test
sample and the method of mounting the sample for the test. In all categories, cables having
at least one conductor of cross-sectional area greater than 35 mm are tested in a spaced
configuration, whereas cables of conductor cross-sectional area of 35 mm or smaller and
optical fibre cables are tested in a touching configuration.
The categories are not necessarily related to different safety levels in actual cable
installations. The actual installed configuration of the cables may be a major determinant in
the level of flame spread occurring in an actual fire.
The method of mounting described as category A F/R (Part 3-21) is intended for special cable
designs used in particular installations.
Categories A, B, C and D (Part 3-22 to Part 3-25 respectively) are for general use where
different non-metallic volumes are applicable.

cables used for the conveyance of energy or signals.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp

[SOURCE: ISO 13943:2017, 3.219]
4 Test environment
The test shall not be carried out if the external wind speed, measured by an anemometer
fitted on the top of the test rig, is greater than 8 m/s and shall not be carried out if the
temperature of the inside walls is below 5 °C or above 40 °C measured at a point
approximately 1 500 mm above floor level, 50 mm from a side wall, and 1 000 mm from the
door. The enclosure door shall be closed throughout the test.
5 Test apparatus
The test apparatus consists of the following.

5.1 Test chamber
The test rig (see Figures 1a) and 1b)) shall comprise a vertical test chamber having a width
of (1 000 ± 100) mm, a depth of (2 000 ± 100) mm and a height of (4 000 ± 100) mm; the floor
of the chamber shall be raised above ground level. The test chamber shall be nominally
airtight along its sides, air being admitted at the base of the test chamber through an aperture
of (800 ± 20) mm × (400 ± 10) mm situated (150 ± 10) mm from the front wall of the test
chamber (see Figure 1).
An outlet (300 ± 30) mm x (1 000 ± 100) mm shall be made at the rear edge of the top of the
test chamber. The back and sides of the test chamber shall be thermally insulated to give a
–2 –1
coefficient of heat transfer of approximately 0,7 W·m ·K . For example, a steel plate
1,5 mm to 2,0 mm thick covered with 65 mm of mineral wool with a suitable external cladding
is satisfactory (see Figure 2). The distance between the ladder and the rear wall of the
chamber is (150 ± 10) mm, and between the bottom rung of the ladder and the floor (400 ±
5) mm. The clearance between the lowest point of the test piece and the floor is
approximately 100 mm (see Figure 3).
5.2 Air supply
A means of supplying a controlled air flow through the chamber shall be fitted.
Air shall be introduced into the test chamber through a box fitted directly underneath, and of
approximately the same dimensions as the air inlet aperture. Air shall be blown into the box
from a suitable fan through a straight section of duct which shall enter from the rear of the
test chamber and be parallel to the floor and along the burner centre line as shown in Figure
1b). The duct shall be arranged to allow air into the box through an opening in the longest
side.
A grille may be placed over the air inlet aperture to facilitate accessing the test chamber but
should neither restrict the airflow nor modify its direction.
A duct of constant cross-section of approximately 240 cm and minimum length of 60 cm is
recommended.
Prior to burner ignition, the air flow shall be adjusted to a rate of (5 000 ± 500) l/min at a
constant controlled temperature of (20 ± 10) °C and at atmospheric pressure and measured
at the inlet side before the test commences. This air flow rate shall be maintained throughout
the test until cable burning or glowing has ceased or for a maximum time of 1 h from
completion of the test flame application period, after which period the flame or glowing shall
be extinguished.
In order to remove noxious gases, it is recommended to maintain the air flow for some
minutes after the end of the test, before entering the test chamber.
5.3 Ladder types
There are two types of tubular steel ladder: a standard ladder of (500 ± 5) mm width and a
wide ladder of (800 ± 10) mm width. Details of the types of ladder are given in Figures 4a)
and 4b).
5.4 Effluent cleaning attachment
Legal requirements may make it necessary for equipment for collecting and washing the
effluent to be fitted to the test chamber. This equipment shall not cause a change in the air
flow rate through the test chamber.

– 8 – IEC 60332-3-10:2018 © IEC 2018
6 Ignition source
6.1 Type
As required by the test procedure the ignition source shall be one or two ribbon-type propane
gas burners complete with venturi mixer, and their own set of flowmeters.
The distance between venturi mixer and burner shall be at least 150 mm. The inner diameter
of the tubing (piping or braided flexible hose) between venturi mixer and burner shall be at
least equal to the 20 mm inner diameter of the outlet of the venturi mixer.
It is recommended that the distance between venturi mixer and burner does not exceed
900 mm.
Bends between venturi mixer and burner should be minimized.
The propane gas shall be technical grade propane of nominal 95 % purity. The flame-
producing surface of the burner(s) shall consist of a flat metal plate through which 242 holes
of 1,32 mm in diameter are drilled on 3,2 mm centres in three staggered rows of 81, 80 and
81 holes each to form an array having the nominal dimensions 257 mm × 4,5 mm. As the
burner plate may be drilled without the use of a drilling jig, the spacing of the holes may vary
slightly. Additionally, a row of small holes may be milled on each side of the burner plate to
serve as pilot holes with the function of keeping the flame burning.
The burners are shown in Figures 5a) and 5b), and the placement of the holes in Figure 6.
To ensure reproducibility between results from different testing stations, a burner, which is
readily available, is recommended for use. For details, see Annex A.
Each burner shall be individually fitted with an accurate means of controlling the propane gas
and air input flow rates, either by means of a rotameter-type flowmeter or mass flowmeter.
Mass flowmeters are recommended for ease of use.
Figure 7 shows an example of a rotameter-type system.
WARNING – The following precautions are recommended to ensure safe operation of the ignition source:
– the gas supply system should be equipped with flashback arresters;
– a flame failure protection device should be used;
– safe sequencing of the propane and air supply should be employed during ignition and extinguishing.
The calibration of the propane gas and air rotameter-type flowmeters shall be checked after
installation to ensure that the pipework and venturi mixer have not affected the calibration.
Corrections for the variations in temperature and pressure from that specified on the propane
gas and air rotameter-type flowmeters shall be applied when necessary, see Annex B.
Propane gas and air rotameter-type flowmeters shall be calibrated according to the following
reference conditions.
Reference temperature and pressure are 20 °C and 1 bar (100 kPa).
For the purposes of this test, the air shall have a dew-point not higher than 0 °C.

The flow rates for the test shall be as follows:
Air (77,7 ± 4,8) l/min at reference conditions (1 bar and 20°C) or (1550 ± 95) mg/s;
Propane (13,5 ± 0,5) l/min at reference conditions (1 bar and 20°C) or (442 ± 11) mg/s;
to provide a nominal 73,7 x 10 J/h (20,5 kW) to each burner.
6.2 Positioning
For the test, the burner shall be arranged horizontally at a distance of (75 ± 5) mm from the
front surface of the cable sample, (630 ± 5) mm above the floor of the test chamber and
approximately symmetrical with the axis of the ladder. The point of application of the burner
flame shall lie between two cross-bars on the ladder (see Figure 2 and Figure 3).
Adjustment of air and gas flows prior to the test may be carried out away from the test
position.
Where two burners are used in combination with the wide ladder, they shall be arranged so
as to be approximately symmetrical with the axis of the ladder, as shown in Figure 5b). The
burner system shall be positioned such that the centre line of the burner system is
approximately coincident with the centre of the ladder.
___________
A net heat of combustion of 46,4 kJ/g is used to calculate the propane flow rate.

Annex B
(informative)
Flowmeter calibration correction factors
B.1 General
When using the rotameter type flowmeters to monitor the supply rate of the gases, two
factors need to be considered in order to use them correctly. It is important
a) to know what the flowmeter is indicating when used under the actual operating conditions;
b) to know under what conditions of temperature and gas pressure the flowmeter was
calibrated, and at what conditions it was designed to operate.
Considering point a), most flowmeters are designed to indicate the volumetric flow rate at
atmospheric temperature and pressure, i.e. 20 °C and 1 bar. However, considering point b),
not all flowmeters are calibrated and designed to work at the same temperature and
pressure, and care should be taken to ensure that the temperature and pressure of the gas
flowing through a flowmeter are correct for that particular meter. Working the flowmeter at
temperatures and pressures different from these conditions requires application of a
correction factor such as provided hereinafter.
B.2 Example
B.2.1 General
Assume that air flow rate of 77,7 l/min at 1 bar and 20 °C is required at the burner.
Flowmeter 1 is calibrated to operate at 2,4 bar absolute and 15 °C, but to indicate l/min at
1 bar and 15 °C.
Flowmeter 2 is calibrated to operate at 1 bar absolute and 20 °C, but to indicate l/min at 1 bar
and 20 °C.
Assume that the air supply pressure up to and including the flowmeters is alternatively at 1
bar (see B.2.2) or at 2,4 bar (see B.2.3) and 20 °C.
The calibration correction factor is given as follows:
P T
C ×
P T
2 1
where
T is the absolute temperature, in kelvins (K);
P is the absolute pressure, in bars (bar);
P , T are the calibration conditions;
1 1
P , T are the operating conditions.
2 2
=
– 20 – IEC 60332-3-10:2018 © IEC 2018
B.2.2 Air supplied at 1 bar
Flowmeter 1
This will require a correction factor to be used since the meter is operating in conditions
removed from its designed operating conditions.
P = 2,4 bar T = 15 °C = 288 K
1 1
P = 1 bar T = 20 °C = 293 K
2 2
Substituting these values:
2,4 293
C × = 1,56
1 288
Thus, to set a flow rate of 77,7 l/min at reference conditions, a reading on this flowmeter of
121,2 l/min (77,7 × 1,56) is required.
Flowmeter 2
Since this meter is operating under its design conditions, the required flow rate of 77,7 l/min
can be read directly from the meter with no correction factor necessary.
B.2.3 Air supplied at 2,4 bar
Flowmeter 1
This will require a correction factor for temperature, but not for pressure since the meter is
operating at its design pressure.
P = 2,4 bar T = 15 °C = 288 K
1 1
P = 2,4 bar T = 20 °C = 293 K
2 2
Substituting these values:
2,4 293
C × = 1,01
2,4 288
Thus, to set a flow rate of 77,7 l/min at reference conditions, a reading of 78,5 l/min
(77,7 × 1,01) on this flowmeter is required.
Flowmeter 2
This will also require a correction factor since it is operating in conditions removed from its
design conditions.
P = 1 bar T = 20 °C = 293 K
1 1
P = 2,4 bar T = 20 °C = 293 K
2 2
=
=
Substituting these values:
1 293
C × = 0,65
2,4 293
Thus, to set a flow rate of 77,7 l/min at reference conditions, a reading of 50,5 l/min
(77,7 × 0,65) on this flowmeter is required.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC 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, l’IEC – 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 l’IEC"). 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 l’IEC, participent
également aux travaux. L’IEC 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 l’IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s'assure de l'exactitude du contenu technique de ses publications; l’IEC 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 l’IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L’IEC 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 l’IEC. L’IEC 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 l’IEC, 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 l’IEC, 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 l’IEC ou de
toute autre Publication de l’IEC, 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 l’IEC peuvent faire
l’objet de droits de brevet. L’IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits
de brevets et de ne pas avoir signalé leur existence.
