(1) The burning rate (B) for each sample is only calculated in the case where the flame reaches the last measuring point or the end of the sample.

The burning rate, B (1) , in millimetres per minute, is given by the formula

When running a series of tests or repeat tests, ensure that the combustion chamber and sample holder have a maximum temperature of 30oC before starting the next test.

In so far as the sample does not ignite or does not continue burning after the burner has been extinguished, or when the flame extinguishes before reaching the first measuring point, so that no burning time is measured note in the test report that the burning rate is 0 mm/min.

Measurement of burning time is completed when the flame has come to the last measuring point or when the flame extinguishes before coming to the last measuring point. If the flame does not reach the last measuring point, measure the burnt distance up to the point where the flame extinguished. Burnt distance is the decomposed part of the sample, which is destroyed on its surface or in the interior by burning.

The measurement of the burning time starts at the moment when the foot of the flame passes the first measuring point. Observe the flame propagation on the side burning faster than the other (upper or lower side).

Push the sample-holder into the combustion chamber so that the end of the sample is exposed to the flame, and after 15 seconds cut off the gas flow.

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.

Place the sample in the sample holder (2.2) so that the exposed side will be downwards to the flame.

Place samples with napped or tufted surfaces on a flat surface and comb twice against the nap using the comb ( 2.5).

The samples shall be conditioned for at least 24 hours but not more than 7 days at a temperature of 23 ± 2oC and a relative humidity of 50 ± 5 % and shall be maintained under these conditions until immediately prior to testing.

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.

Composite materials (see point 2.10 of Annex I) shall be tested as if they were of uniform construction.

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.

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.

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.

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.

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;

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:

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.

Before the test, the vertical velocity of the air through the fume cupboard shall be measured 100 mm in front of and behind the final position where the combustion chamber will be located. It shall be between 0,10 and 0,30 m/s in order to avoid possible discomfort, by combustion products, to the operator. It is possible to use a fume cupboard with a natural ventilation and an appropriate air velocity.

Fume cupboard. The combustion chamber may be placed in a fume cupboard assembly provided that the internal volume is at least 20 times, but not more than 110 times, greater than the volume of the combustion chamber and provided that no single height, width, or length dimension of the fume cupboard is greater than 21/2 times either of the other two dimensions.

Metal comb, at least 110 mm in length, with seven to eight smooth rounded teeth per 25 mm.

Test gas. The gas supplied to the burner shall have a calorific value near 38 MJ/m3 (for example natural gas).

Gas burner. The small ignition source is provided by a Bunsen burner having an inside diameter of 9,5 ± 0,5 mm. It is located in the test cabinet so that the centre of its nozzle is 1 9 mm below the centre of the bottom edge of the open end of the sample (see figure 2).

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).

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 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.

Sample holder, consisting of two U-shaped metal plates or frames of corrosion-proof material. Dimensions are given in figure 4.

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.

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.

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.

A sample is held horizontally in a U-shaped holder and is exposed to the action of a defined low-energy 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.

ANNEX V

TEST TO DETERMINE THE MELTING BEHAVIOUR OF MATERIALS

1. Principle

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) an electric radiator;

(b) a support for the sample with grill;

(c) a receptacle (for resultant drops);

(d) 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/cm2.

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/cm2 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 watercooled 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.

2.2.1. Calibration check

The irradiance produced by the power input which the initial calibration has shown to correspond to an irradiance of 3 W/cm2 shall be frequently checked (at least once every 50 operating hours) and the apparatus shall be recalibrated if such a check reveals a deviation greater than 0,06 W/cm2.

2.2.2. Calibration procedure

The apparatus shall be placed in an environment essentially free of air currents (not more than 0,2 m/s).

Place the heat flux meter in the apparatus in the specimen position so that the target of the heat flux meter is located centrally within the radiator surface.

Switch on the electricity supply and establish the power input of the controller required to produce irradiance at the centre of the radiator surface of 3 W/cm2. Adjustment to the power unit to record 3 W/cm2 should be followed by a five minute-period without further adjustment to ensure equilibrium.

2.3. The support for the samples shall be a metallic ring (figure 1). On top of this support a grill, made of stainless steel-wire, is placed with the following dimensions:

— interior diameter: 118 mm,

— dimension of the holes: 2,10 mm square,

— diameter of the steel-wire: 0,70 mm.

2.4. The receptacle shall consist of a cylindrical tube with an interior diameter of 118 mm and a depth of 12 mm.

The receptacle shall be filled with cotton wool.

2.5. A vertical column shall support the items specified in paragraph 2.1, 2.3 and 2.4.

The radiator is placed on top of the support in a manner such that the radiating surface is horizontal and the radiation is downwards.

A lever/pedal shall be provided in the column to lift the support of the radiator slowly. It shall also be provided with a catch in order to ensure that the radiator can be brought back in its normal position.

In their normal position, the axes of the radiator, the support for the sample and the receptacle must coincide.

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 2.8 of Annex I) 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 ± 2 o 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 upperside 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) 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.

(ii) 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.

5. Results

Observed phenomena shall be noted in the test-report, such as:

— the fall of drops, if any, whether flaming or not,
