3. PREPARATION OF TEST PIECE
(1) Target products are materials within the range of 13 (1) mm deep from the vehicle interior surface.
(2) The test piece shall be cut from the product as shown in Figure 4. Draw 3 lines on the reverse side as
shown in Figure 4. Cut off the corners to facilitate mounting for the equipment. If it is difficult to take the
test piece due to the shape of the part or the like, it is allowable to use test pieces with the same
specifications as the product, such as materials, manufacturing method, plate thickness, product shape
(speaker grill hole, etc.), specific gravity, and coated/not coated. For test pieces that exceed 300
seconds of burning time to reach the second measuring point, it is allowable to draw a line at the
position where the burning time exceeds 300 seconds and measure the burning time up to the line.

or length. However, for judgment of self-extinguishing, dimension of 80 mm or more shall be required at
least. Metal materials and products that fit inside a sphere with a diameter of 80 mm are excluded.
(4) If the surface material consists of more than two types of material (2) and is completely bonded or fused,
the material will be treated as a composite material and be used as is.
(5) If the surface material consists of more than two types of material (2) and neither are completely bonded
nor fused, the test pieces shall be cut out individually and shall be not more than 13 mm (1) thick.
(6) A material measuring more than 13 mm (1) thick shall be cut out to 13 mm (1) thickness from the exposed
car interior surface for use as a test piece.
(7) A part bonded and installed to the body panel shall be peeled off with a scraper and shall be used as a
test piece.
(8) Flammability varies with sampling direction and also with color of test pieces. Therefore, preliminary
testing should be conducted for the sampling direction and color in accordance with Items 7. and 8. on
following page. The most flammable test pieces shall be used. For the following materials, processes,
and part shapes, preliminary test shall be performed for sampling direction of test pieces. Make sure
which sampling direction easily burns. Test pieces shall then be prepared in that direction.

4. CONDITIONING OF TEST PIECE


a) Allow the test piece to stand in an environmental condition of 23 ± 2°C and relative humidity of 50 ± 5%
for 24 to 168 hours (1).
b) After conducting the heat aging test at 80C for 168 hours, immediately condition the test piece as in a).
(Applicable parts shall be limited as follows.)
Heat aging test parts: Fabric trim cover for seat, seat pad urethane, fabric surface material and cushion
material which are not completely bonded.
Note (1) When adjusting the condition of the test piece, the maximum and minimum temperature and
relative humidity shall be recorded by an automatic recording device, etc.
However, if it is unavoidable, the method of measuring and recording every hour is also acceptable.
5. TEST ATMOSPHERE
(1) Temperature 20  5°C, relative humidity 55  5% (1).
(2) Prior to starting the test, stop ventilation in the test room and seal the entrance/exit to prevent the wind
from affecting the test.
(3) To maintain a draftless condition surrounding the test cabinet, the cabinet is placed inside a draft
chamber.
Prior to the test, measure the vertical velocity of the air through a draft chamber 100 mm in front of and
behind the position where the combustion test device will be located. To avoid combustion gas
inhalation by the tester as much as possible, the air velocity shall be between 0.1 m/s to 0.3 m/s.
The upper damper of draft chamber is opened for natural ventilation.
(4) Subsequent to test completion, ventilation is immediately started and the test room is restored to the
condition in Item (1).
Note (1) At the time of the combustion test, keep the condition in one which the MAX and MIN temperature
and relative humidity can be checked.
6. NUMBER OF TEST PIECES

7. CONFIRMATION AND ADJUSTMENT OF TEST PROCEDURES


7.1 Confirmation of test equipment
(1) Mount the test piece clamp on the support stand. Confirm that the test piece clamp's open side is centered as
illustrated in Figure 6.
Unit: mm

Flame top

Specimen Burner tip


Specimen clamp

Figure 6 Test piece clamp and burner position


(2) Open the door with attached burner and ignite the Bunsen burner. Adjust the flame top height to touch the flame
height gauge (38 mm). Confirm that there is no flickering of flame.
(3) Carefully close door with attached burner and ensure there is no flame flicker. Confirm that the flame persists for 15
seconds after the door is closed.

8. REGULAR TEST
(1) The conditioned test piece, with the surface that is exposed to the automobile's interior facing down, is secured
between the two test piece clamps with open side ends aligned and mounted on the test piece support stand. It is
then placed on the support stand inside the test cabinet. Confirm the test piece positioned is as described in Item
7.1(1).
1) In cases where a test piece cannot maintain a horizontal position while burning, or when it is small, fuzzy or
gridded, the following procedures are recommended.
[1] For a test piece whose end is softened or deformed by heat, preventing it from being burned in the horizontal
position, attach fine heat-resistant wires at 25 mm intervals across the width of the test piece clamp. This will
support the test piece and maintain a horizontal burning position. For the following materials, use a clamp with
wires for the test if the heat of combustion causes the test piece to sag and the burn rate of horizontal
combustion cannot be measured.
Table 1 Materials which may sag and examples of their application
Material Example of application
Rubber Various insulator, etc.
Urethane Seat, sun visor, etc.
Fabric (single or composite) Seat, sun visor, etc.
PVC covering Seat, sun visor, etc.
Carpet Floor carpet, luggage carpet, etc.
Felt (single) Roof insulator, etc.
[2] A test piece that cannot be held with the test piece clamp shall be supported by the clamp with wires described
above.
[3] For a test piece with fuzzy surface, fluff twice with a comb having rounded tip teeth spaced 7 or 8 teeth per 25
mm.
[4] For a test piece with gridded shape like speaker grill which is made of uniform material, if the grid is less than
293 mm, carry out the flammbility test from the end of the test piece (non-gridded part). If the grid is 294 mm or
more, carry out the flammbility test only at the gridded part.
2) If it is anticipated that flammability will differ with the operating procedures, such as clamping of the test piece and
flame approach speed, preliminary tests shall be conducted. Conditions where burning occurs most easily shall be
selected for the test.
(2) Ignite the Bunsen burner and close the door with burner carefully so that flame will not flicker. Apply flame to the
piece for 15 seconds and then extinguish the Bunsen burner.
(3) When the test piece starts to burn and as soon as the flame reaches the marked first measuring point, start time
measurement with a stopwatch. End the measurement as soon as the flame passes the marked the last measuring
point. If the flame extinguishes before reaching the marked the last measuring point, measure the distance and
time from the marked first measuring point to the leading burned edge. Definition of burning and the position of
measurement are shown in Reference Figure 1. Also, when the burning speed differs between the top and the
bottom surfaces, the higher burning speed shall be taken by visual observation.
If the flame edge is not visible due to smoking, place strings at the upper and lower surfaces of the test piece as
shown in Reference Figure 2. Passing of flame is determined when one string is cut earlier than the other. Strings
shall be cotton string #50 (JIS L 2101 Cotton sewing thread) or equivalent.
(4) If burning does not reach marked line B after 5 minutes, the test can be completed by measuring duration and
distance at that point.

5
M0094_2022-N

(5) The burn rate can be obtained using the following formula:
D
B  60
T
where, B: Burn rate (mm/min)
D: Burn distance (mm)
T: Burn time (sec)
Remark 1: During inspection of the specimen, flames propagating along surface tufts shall not be regarded
as combustion.

9. REPORT

(1) If the flame goes out spontaneously within 50 mm after it passes the first measuring point and the
elapsed time is less than 60 seconds, the burn rate shall be indicated as SE (1). Burning time, burning
distance, max./min. values of temperature and humidity of the test piece conditioning, conditioning time
of the test piece, and max./min. values of temperature and humidity in the combustion room must be
recorded.

(2) In cases when the test piece is not ignited or the flame terminates spontaneously before reaching the
marked first measuring point, the burn rate shall be indicated as 0.
