...

C.1. Sampling method

C.1.1. Five samples of an isotropic material shall be tested or ten samples of a non-isotropic material shall be tested (five for each direction).

C.1.2. Samples must be extracted from the material tested. If the burning rates in different directions vary, each direction must be tested. Samples must be taken and placed in test apparatuses in such a manner that the highest burning rate can be determined. When the material is supplied in widths, a length of at least 500 mm shall first be cut, covering the entire width; thence, equidistant samples with length of at least 100 mm shall be taken from the material edge. The sampling of finished products shall follow the similar method if feasible as per the shape of the product. When the thickness of the finished product is more than 13 mm, it must be reduced to 13 mm through a mechanical process applied to the surface not facing towards the passenger compartment. If such reduction is not viable, tests shall be carried out on the initial thickness of the material, which must be stated in the test report.

Composite materials must be tested (see Clause 1.3.11) if they have uniform composition. If materials are made of superimposed layers of different compositions that are not composite materials, all layers of such materials within a depth of 13 mm from the surface facing towards the passenger compartment shall be tested separately.

C.1.3. Samples shall be held horizontally in a U-shaped holder and are exposed to the action of a flame acting on the free end of the holder in 15 seconds in a combustion chamber.

C.2. Test apparatus

C.2.1. Combustion chamber (see Figure C.1), made of stainless steel in dimensions specified in Figure C.2. The front of the chamber contains a fire-resistant observation window. Such window may cover the front and be constructed as an access panel.

The bottom of the chamber has vent holes and the top has vent slots all around. The combustion chamber is 10 mm high and shall be placed on four feet.

The chamber may have one hole at one end for the insertion of the sample holder; at the opposite end, another hole is available for the gas line. Melted material escapes into a tray (see Figure C.3), which is placed on the bottom of the chamber between vent holes. The tray must not mantle any areas of the vent holes.

...

...

...

The lower plate is equipped with pins matched by holes in the upper plate to assure a firm grip of the sample. The pins also serve as measuring points at the beginning and end of the burning distance.

Heat resistant supportive wires 0.25 mm in diameter shall span at 25-mm intervals over the U-shaped frame at the bottom.

The plane of the lower side of samples must be 178 mm above the floor plate of the chamber. The distance of the front edge of the sample holder from the other end of the chamber must be 22 mm. The distance of longitudinal sides of the sample holder from the sides of the chamber must be 50 mm (all dimensions are measured inside the chamber) (see Figure C.1 and Figure C.2).

C.2.3. Gas burner

A Bunsen burner with a diameter of 9.5 mm ± 0.5 mm provides the ignition source. The ignition source is so located in the test cabinet that the center of the burner’s nozzle is 19 mm below the center of the bottom edge of the open end of the sample (see Figure C.2).

C.2.4. Test gas

The gas supplied to the burner must have a calorific value near 38 MJ/m³ (e.g. natural gas, LPG)

C.2.5. Metal comb at least 110 mm in length with 7 to 8 smooth rounded teeth per 25 mm.

C.2.6. Stop swatch accurate to 0.5 second.

C.2.7. Fume cupboard

The combustion chamber may be placed in a fume cupboard provided that the internal volume of the cupboard is at least 20 times but at most 110 times greater than the chamber. Moreover, one of three dimensions including the length, width or height of the cupboard must not be 2.5 times larger than the other two dimensions. Before the test, the vertical velocity of the air passing through the fume cupboard must be measured 100 mm before and behind the location of the chamber. Such velocity must range from 0.10 m/s to 0.30 m/s in order to prevent combustion products from causing discomfort to the operator. A fume cupboard with natural ventilation and appropriate air velocity may be utilized.

C.3. Samples

...

...

...

C.3.1.1. The shape and dimensions of samples are shown in Figure C.6. The thickness of samples shall match that of the products to be tested. Thickness must not exceed 13 mm. Samples, when taken, must have a constant section over its entire length.

Figure C.6: Sample

 (Dimensions are shown in millimeters)

C.3.1.2. If the shape and dimensions of a product do not permit the extraction of samples by given dimensions, these minimum dimensions must be followed:

 (a) For samples having a width of 3 mm to 60 mm, the length shall be 356 mm. In this case, the material is tested in the product’s width;

 (b) For samples having a width of 60 mm to 100 mm, the minimum length shall be 138 mm. In this case, the potential burning distance corresponds with the length of the sample. Data shall be measured from the first measuring point.

C.3.2. Test condition

Samples must be kept in ambient temperatures of 23°C ± 2°C and relative humidity of 50% ± 5% in at least 24 hours but not more than 7 days. Such condition must be maintained until the instant before the start of the test.

...

...

...

C.4.1. First, the sample with napped or tufted surfaces shall be laid on a flat surface and brushed with a metal comb twice against the nap (see Clause C.2.5).

C.4.2. The sample shall be then placed in the sample holder (see Clause C.2.2) in such a manner that the exposed side lies face downwards to the flame.

C.4.3. The gas flame shall then be adjusted to a height of 38 mm according to the mark in the combustion chamber and the air intake of the closed burner. Before the start of the first test, the flame must burn stably in at least one minute.

C.4.4. The sample holder is inserted into the chamber in such a way that the sample's end is exposed to the flame. Gas flow shall be then cut off after 15 seconds.

C.4.5. The burning time shall be measured upon the flame's licking the first measuring point. The propagation of the flame shall be monitored on the side that burns faster than the other (upper or lower side).

C.4.6. The measured burning time stops when the flame reaches the last measuring point or when the flame dies before reaching the last measuring point. If the flame does not reach the last measuring point, the burning distance shall be measured up to the point where the flame extinguishes. The burning distance refers to the decomposed part of the sample, whose surface or interior is destroyed.

C.4.7. If the sample does not catch fire or stops burning upon the extinguishment of the burner (i.e. the burning time is not measurable), the test report shall indicate the burning rate at 0 mm/minute. The sample applies to the circumstance in which the flame dies before reaching the first measuring point.

C.4.8. When a series of tests is carried out or a test is repeated, the maximum temperature of the chamber and the sample holder must be maintained at 30^oC prior to the following test.

C.5. Calculation

...

...

...

B = 60 S/t

Including:

S - the burning distance, in millimeters;

t - the time consumed, in seconds, to burn the distance S.

The burning rate (B) of each sample shall only be calculated when the flame reaches the last measuring point or burn to the end of the sample.

ANNEX D

TESTING OF MELTING BEHAVIOR OF MATERIALS

D.1. Sampling method

...

...

...

D.1.2. Each sample is inserted in horizontal position into an electric radiator. A receptacle is placed under the sample to collect the resultant drops. Some cotton wool is put on the receptacle to verify if any drops ignite flame.

Apparatuses shall consist of (see Figure D.1):

 (a) An electric radiator;

 (b) A sample holder with grill;

 (c) A receptacle (for resultant drops);

 (d) A stand (for the fitting of the apparatuses)

D.2.1. The electric radiator with useful output of 500 W is the source of heat. The radiating surface must be made of a transparent quartz plate 100 mm ± 5 mm in diameter.

The heat radiating from the apparatuses shall be measured on a surface that is parallel to the radiator’s surface at a distance of 30 mm. Such heat must reach 3 W/cm².

...

...

...

 (a) interior diameter: 118 mm;

 (b) dimension of grill’s hole: 2.10 mm square; (c) diameter of steel wire: 0.70 mm. D.2.3. The receptacle shall consist of a cylindrical tube with interior diameter of 118 mm and depth of 12 mm. The receptacle must be filled with cotton wool.

D.2.4. A vertical stand shall hold the apparatuses as stated in Clause D.2.1, D.2.2 and D.2.3.

The radiator is attached to the top of the stand in such a manner that the heat-radiating surface is horizontal and downward.

A level or pedal shall be fitted in the stand to elevate the radiator holder gradually. A catch must also be provided to return the radiator back to its normal position.

The radiator’s axis, the sample holder and the receptacle, in their normal positions, must match each other.

D.3. Samples

D.3.1. The dimensions of a test sample must be 70 mm x 70 mm. Samples must be extracted from finished products in a same manner when the shape of the finished products permits such extraction. When the thickness of the finished product is more than 13 mm, it must be reduced to 13 mm through a mechanical process applied to the surface not facing towards the passenger compartment. If such reduction is not viable, tests shall be carried out on the initial thickness of the material, which must be indicated in the test report.

D.3.2. Composite materials (see Clause 1.3.11) must be tested if they have uniform composition.

...

...

...

D.3.4. The total mass of the sample tested must be at least 2 g. If the mass of one material is lower than such value, samples must be added to suffice.

D.3.5. If two faces of the material differ, both faces shall be tested. In other words, eight samples shall undergo the test. Samples and cotton wool must be kept in ambient temperatures of 23°C ± 2°C and relative humidity of 50% ± 5% in at least 24 hours. Such condition shall be maintained until the instant immediately preceding the test.

D.4. Test procedure

D.4.1. The sample is placed on the sample holder. The holder is so positioned that the distance between the radiator’s surface and the upper side of the sample is 30 mm.

D.4.2. The receptacle filled with cotton wool is located beneath the grill of the sample holder at a distance of 300 mm.

D.4.3. The radiator is put aside before being switched on to avoid the radiation of heat onto the sample. When the radiator reaches its full testing capacity, it is placed above the sample and timing starts.

D.4.4. If the material melts or deforms, the height of the radiator must be adjusted to be maintained at the distance of 30 mm.

D.4.5. If the material burns, the radiator shall be moved aside after 3 seconds. The radiator is returned in position when the flame languishes. The procedure is similarly repeated as frequently as necessary during the first five minutes of the test.

After the fifth minute of the test:

...

...

...

 (ii) If the material is on fire, the flame has to extinguish before the radiator returns into position again.

In both cases, the test must carry on for another five minutes.

D.5. Test result

Events observed have to be transcribed into the report, for example:

 (i) formation of any drops, whether flammable or not;

 (ii) ignition of cotton wool.
