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 500mm shall be cut
covering the entire width. From this the samples shall be taken so as to be at least 100mm
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 13mm, it shall be reduced to 13mm by a mechanical process applied to
the side which does not face the respective compartment (interior, engine or separate heating
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 13mm
from the surface facing towards the respective 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 15s 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, 10mm 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 0.25mm diameter heat resistant wires spanning the
frame at 25mm intervals over the bottom U-shaped frame (see Figure 5).
The plane of the lower side of samples shall be 178mm above the floor plate. The distance of
the front edge of the sample holder from the end of the chamber shall be 22mm; the distance of
the longitudinal sides of the sample holder from the sides of the chamber shall be 50mm (all
inside dimensions). (See Figures 1 and 2)
Figure 4
Example of Sample Holder
(Dimensions in millimeters)

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 13mm.
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 60mm, the length shall be 356mm. In this case the
material is tested in the product's width;
For samples having a width of 60 to 100mm, the length shall be at least 138mm. 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 38mm 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 ± 5mm.
The radiated heat from the apparatus, measured on a surface which is situated parallel to the
surface of the radiator at a distance of 30mm, 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 10mm 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 25mm.
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: 70mm × 70mm. 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 13mm, it shall be reduced to 13mm by a mechanical process applied to
the side which does not face the respective compartment (interior, engine or separate heating
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 13mm from the surface
facing towards the respective compartment (interior, engine or separate heating 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 30mm.
The receptacle, including the cotton wool, is placed beneath the grill of the support at a
distance of 300mm.
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
30mm.
If the material ignites, the radiator is put aside 3s 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 shall 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 560mm high and shall have two
rigidly connected parallel rods spaced 150mm apart on which pins shall be fitted for mounting
the test specimen which is located in a plane at least 20mm from the frame. The mounting pins
shall be not greater than 2mm in diameter and at least 27mm 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 2mm 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 20mm.

4.4. The marker threads shall be attached horizontally in front of and behind the specimen at the
locations shown in Figure 1. At each location, a loop of thread shall be mounted so that the
two segments are spaced 1mm and 5mm from the front and rearface of the specimen.
Each loop shall be attached to a suitable timing device. Sufficient tension shall be imposed to
the threads to maintain its position relative to the specimen.
4.5. The flame shall be applied to the specimen for 5s. Ignition shall be deemed to have occurred if
flaming of the specimen continues for 5s after removal of the igniting flame. If ignition does not
occur, the flame shall be applied for 15s to another conditioned specimen.
4.6. If any result in any set of three specimens exceeds the minimum result by 50%, another set of
three specimens shall be tested for that direction or face. If one or two specimens in any set of
three specimens fail to burn to the top marker thread, another set of three specimens shall be
tested for that direction or face.
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 one of the first
marker threads (t );
From the start of the application of the igniting flame to the severance of one of the
second marker threads (t );
From the start of the application of the igniting flame to the severance of one of the third
marker threads (t ).
4.8. If the sample does not ignite or does not continue burning after the burner has been
extinguished or if the flame extinguishes before the destruction of one of the first marker
threads occurred, so that no burning time is measured, the burning rate is considered to be
0mm/min.
4.9. If the sample does ignite and the flames of the burning sample do reach the height of the third
marker threads without destroying the first and second marker threads (e.g. due to material
characteristics of thin material sample), the burning rate is considered to be more than
100mm/min.
5. RESULTS
The observed phenomena shall be written down in the test-report, to include:
(a)
(b)
The durations of combustion: t , t and t in seconds, and
The corresponding burnt distances: d , d and d inmm.
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 threads) as follows:
V = 60 d /t (mm/min)
The highest burning rate of V , V and V shall be taken into account.

TEST TO DETERMINE THE CAPABILITY OF MATERIALS TO REPEL FUEL OR LUBRICANT
1. SCOPE
This Annex lists prescriptions to test the capability of insulation materials used in engine
compartments and separate heating compartments.
2. SAMPLING AND PRINCIPLE
2.1. The test samples shall measure: 140mm × 140mm.
2.2. The thickness of the samples shall be 5mm. If the thickness of the test sample is more than
5mm, it shall be reduced to 5mm by a mechanical process applied to the side which does not
face the engine compartment or separate heating compartment.
2.3. The test liquid shall be diesel fuel according to Standard EN 590:1999 (Market fuels). or
alternatively diesel fuel according to Regulation No. 83 (Annex 10: Specification of reference
fuels).
2.4. Four samples shall undergo the test.
