ANNEX 6
TEST TO DETERMINE THE HORIZONTAL BURNING RATE OF MATERIALS
1. SAMPLING AND PRINCIPLE
1.1. Five samples shall undergo the test in the case of an isotropic material or ten samples in the
case of a non-isotropic material (five for each direction).
1.2. The samples shall be taken from the material under test. In materials having different burning
rates in different material directions, each direction has to be tested. The samples are to be
taken and placed in the test apparatus so that the highest burning rate will be
measured. When the material is supplied in widths, a length of at least 500 mm shall be cut
covering the entire width. From this the samples shall be taken so as to be at least 100 mm
from the material edge and equidistant from each other. Samples shall be taken in the same
way from finished products, when the shape of the product permits. When the thickness of the
product is more than 13 mm, it shall be reduced to 13 mm by a mechanical process applied to
the side which does not face the occupant compartment. If it is impossible, the test shall be
carried out, in accordance with the Technical Service, on the initial thickness of the material,
which shall be mentioned in the test report.
Composite materials (see Paragraph 6.1.3.) shall be tested as if they were of uniform
construction. In the case of materials made of superimposed layers of different composition
which are not composite materials, all the layers of material included within a depth of 13 mm
from the surface facing towards the passenger compartment shall be tested individually.
1.3. A sample is held horizontally in a U-shaped holder and is exposed to the action of a defined
flame for 15 seconds in a combustion chamber, the flame acting on the free end of the
sample. The test determines if and when the flame extinguishes or the time in which the flame
passes a measured distance.
2. APPARATUS
2.1. Combustion chamber (Figure 1), preferably of stainless steel and having the dimensions given
in Figure 2. The front of the chamber contains a flame-resistant observation window, which
may cover the front and which can be constructed as an access panel.
The bottom of the chamber has vent holes, and the top has a vent slot all around. The
combustion chamber is placed on four feet, 10 mm high.
The chamber may have a hole at one end for the introduction of the sample holder containing
the sample; in the opposite end, a hole is provided for the gas line. Melted material is caught in
a pan (see Figure 3) which is placed on the bottom of the chamber between vent holes without
covering any vent hole area.

Figure 3
Typical Drip Pan
(Dimensions in millimetres)
2.2. Sample holder, consisting of two U-shaped metal plates or frames of corrosion-proof
material. Dimensions are given in Figure 4.
The lower plate is equipped with pins, the upper one with corresponding holes in order to
ensure a consistent holding of the sample. The pins also serve as the measuring points at the
beginning and end of the burning distance.
A support shall be provided in the form of 0.25 mm diameter heat resistant wires spanning the
frame at 25 mm intervals over the bottom U-shaped frame (see Figure 5).
The plane of the lower side of samples shall be 178 mm above the floor plate. The distance of
the front edge of the sample holder from the end of the chamber shall be 22 mm; the distance
of the longitudinal sides of the sample holder from the sides of the chamber shall be 50 mm (all
inside dimensions). (See Figures 1 and 2)
Figure 4
Example of Sample Holder
(Dimensions in millimeter)

3. SAMPLES
3.1. Shape and Dimensions
3.1.1. The shape and dimensions of samples are given in Figure 6. The thickness of the sample
corresponds to the thickness of the product to be tested. It shall not be more than 13 mm.
When taking the sample permits, the sample shall have a constant section over its entire
length.
Figure 6
Sample
(Dimensions in millimetres)
3.1.2. If the shape and dimensions of a product do not permit taking a sample of the given size, the
following minimum dimensions shall be maintained:
(a)
(b)
For samples having a width of 3 to 60 mm, the length shall be 356 mm. In this case the
material is tested in the product's width;
For samples having a width of 60 to 100 mm, the length shall be at least 138 mm. In this
case the potential burning distance corresponds to the length of the sample, the
measurement starting at the first measuring point.
3.2. Conditioning
The samples shall be conditioned for at least 24 hours but not more than 7 days at a
temperature of 23° C ± 2° C and a relative humidity of 50 ± 5% and shall be maintained under
these conditions until immediately prior to testing.
4. PROCEDURE
4.1. Place samples with napped or tufted surfaces on a flat surface and comb twice against the nap
using the comb (Paragraph 2.5.).
4.2. Place the sample in the sample holder (Paragraph 2.2.) so that the exposed side will be
downwards to the flame.
4.3. Adjust the gas flame to a height of 38 mm using the mark in the chamber, the air intake of the
burner being closed. Before starting the first test, the flame shall burn at least for 1 min for
stabilization.

ANNEX 7
TEST TO DETERMINE THE MELTING BEHAVIOUR OF MATERIALS
1. SAMPLING AND PRINCIPLE
1.1. Four samples, for both faces (if they are not identical) shall undergo the test.
1.2. A sample is placed in a horizontal position and is exposed to an electric radiator. A receptacle
is positioned under the specimen to collect the resultant drops. Some cotton wool is put in this
receptacle in order to verify if any drop is flaming.
2. APPARATUS
The apparatus shall consist of (Figure 1):
(a)
(b)
(c)
(d)
An electric radiator;
A support for the sample with grill;
A receptacle (for resultant drops);
A support (for the apparatus)
2.1. The source of heat is an electric radiator with a useful output of 500 W. The radiating surface
must be made of a transparent quartz plate with a diameter of 100 ± 5 mm.
The radiated heat from the apparatus, measured on a surface which is situated parallel to the
surface of the radiator at a distance of 30 mm, shall be 3 W/cm .
2.2. Calibration
For calibration of the radiator, a heat flux meter (radiometer) of the Gardon (foil) type with a
design range not exceeding 10 W/cm shall be used. The target receiving radiation, and
possibly to a small extent convection, shall be flat, circular, not more than 10 mm in diameter
and coated with a durable matt black finish.
The target shall be contained within a water cooled body the front face of which shall be of
highly polished metal, flat, coinciding with the plane of the target and circular, with a diameter of
about 25 mm.
Radiation shall not pass through any window before reaching the target.
The instrument shall be robust, simple to set up and use, insensitive to draughts, and stable in
calibration. The instrument shall have an accuracy of within ± 3% and a repeatability within
0.5%.
The calibration of the heat flux meter shall be checked whenever a recalibration of the radiator
is carried out, by comparison with an instrument held as a reference standard and not used for
any other purpose.
The reference standard instrument shall be fully calibrated at yearly intervals in accordance
with a national standard.

3. SAMPLES
The test samples shall measure: 70 mm x 70 mm. Samples shall be taken in the same way
from finished products, when the shape of the product permits. When the thickness of the
product is more than 13 mm, it shall be reduced to 13 mm by a mechanical process applied to
the side which does not face the occupant compartment. If it is impossible, the test shall be
carried out, in accordance with the Technical Service, on the initial width of the material which
shall be mentioned in the test report.
Composite materials (see Paragraph 6.1.3. of the Regulation) shall be tested as if they were of
uniform construction.
In the case of materials made of superimposed layers of different composition which are not
composite materials, all the layers of material included within a depth of 13 mm from the
surface facing towards the passenger compartment shall be tested individually.
The total mass of the sample to be tested shall be at least 2 g. If the mass of one sample is
less, a sufficient number of samples shall be added.
If the two faces of the material differ, both faces must be tested, which means that eight
samples are to be tested. The samples and the cotton wool shall be conditioned for at least
24 hours at a temperature 23° C ± 2° C and a relative humidity of 50 ± 5% and shall be
maintained under these conditions until immediately prior to testing.
4. PROCEDURE
The sample is placed on the support and the latter is so positioned that the distance between
the surface of the radiator and the upper side of the sample is 30 mm.
The receptacle, including the cotton wool, is placed beneath the grill of the support at a
distance of 300 mm.
The radiator is put aside, so that it cannot radiate on the sample, and switched on. When it is
on full capacity it is positioned above the sample and timing is started.
If the material melts or deforms, the height of the radiator is modified to maintain the distance of
30 mm.
If the material ignites, the radiator is put aside three seconds afterwards. It is brought back in
position when the flame has extinguished and the same procedure is repeated as frequently as
necessary during the first five minutes of the test.
After the fifth minute of the test:
(i)
(ii)
If the sample has extinguished (whether or not it has ignited during the first five minutes
of the test) leave the radiator in position even if the sample reignites,
If the material is flaming, await extinction before bringing the radiator into position again.
In either case, the test must be continued for an additional five minutes.

ANNEX 8
TEST TO DETERMINE THE VERTICAL BURNING RATE OF MATERIALS
1. SAMPLING AND PRINCIPLE
1.1. Three samples shall undergo the test in the case of an isotropic material, or six samples in the
case of a non-isotropic material.
1.2. This test consists of exposing samples, held in a vertical position, to a flame and determining
the speed of propagation of the flame over the material to be tested.
2. APPARATUS
The apparatus shall consist of:
(a)
(b)
(c)
(d)
(e)
A specimen holder;
A burner;
A ventilation system to extract gas and combustion products;
A template;
Marker threads of white mercerized cotton threads having a maximum linear density of
50 tex.
2.1. The specimen holder shall consist of a rectangular frame of 560 mm high and shall have two
rigidly connected parallel rods spaced 150 mm apart on which pins shall be fitted for mounting
the test specimen which is located in a plane at least 20 mm from the frame. The mounting
pins shall be not greater than 2 mm in diameter and at least 27 mm long. The pins shall be
located on the parallel rods at locations shown in Figure 1. The frame shall be fitted onto a
suitable support to maintain the rods in a vertical orientation during testing (for the purpose of
locating the specimen on the pins in a plane away from the frame, spacer stubs 2 mm in
diameter may be provided adjacent to the pins).
2.2. The burner is described in Figure 3.
The gas supplied to the burner can be either commercial propane gas or commercial butane
gas.
The burner shall be positioned in front of, but below, the specimen such that it lies in a plane
passing through the vertical centerline of the specimen and perpendicular to its face (see
Figure 2), such that the longitudinal axis is inclined upwards at 30° to the vertical towards the
lower edge of the specimen. The distance between the tip of the burner and the lower edge of
the specimen shall be 20 mm.

4.7. The following times, in seconds, shall be measured:
(a)
(b)
(c)
From the start of the application of the igniting flame to the severance of the first marker
thread (t );
From the start of the application of the igniting flame to the severance of the second
marker thread (t );
From the start of the application of the igniting flame to the severance of the third marker
thread (t ).
5. RESULTS
The observed phenomena shall be written down in the test-report, to include:
(i)
(ii)
The durations of combustion: t , t and t in seconds, and
The corresponding burnt distances: d , d and d in mm.
The burning rate V and the rates V and V , if applicable, shall be calculated (for each sample
if the flame reaches at least the first marker thread) as follows:
V = 60 d /t (mm/min)
The highest burning rate of V , V and V shall be taken into account.
