Requirement of vertical flammability characteristic
and test method for certain category automobile
interior material
1 Scope
This Standard specifies the technical requirements of vertical flammability
characteristic and test methods for certain category automobile interior material.
This Standard is applicable to interior curtains, sun shades and/or other interior
materials for M3 vehicles that are used to carry more than 22 passengers; it is
not applicable to city buses that have standing passengers.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1 burning rate
The ratio between combustion distance and time used, in millimeters per minute
(mm/min).
2.2 interior material
Interior curtains, sun shades and/or other interior material.
3 Technical requirements
Vertical burning rate shall not exceed 100 mm/min.
4 Test methods
4.1 Principle
Vertically fix the specimen on the rectangular frame. Use the predetermined
flame to ignite specimen in the combustion chamber. Determine the combustion
distance and time used of the specimen.
4.2 Test equipment and appliances
4.2.8 Fuming hood
The specimen holder shall be placed in the fuming hood. The internal volume
of fuming hood is 20 ~ 110 times specimen holder volume. Any one among the
fuming hood’s length, width and height must not exceed 2 times any size of the
other two sizes.
Before the test, measure the vertical speed of air flowing through the fuming
hood at 100 mm before and after the final determined position of specimen
holder. The speed shall be within 0.10 m/s ~ 0.30 m/s. The fuming hood can
use natural ventilation or proper wind speed ventilation.
4.3 Specimen
4.3.1 Size
The size of specimen. length is 560 mm ± 2 mm; width is 170 mm ± 2 mm; the
thickness is component thickness.
4.3.2 Sampling
Respectively take 3 blocks (or more) of specimens vertically and zonally for
burning test. The sampling goes as follows.
a) if the shape and size of component comply with sampling requirements,
the sample shall be made out of component;
b) If the shape and size of component does not comply with sampling
requirements, it shall use standard specimen made of same material, in
same processing, of which structure and component are the same, for
test;
c) when material is supplied according to the entire width, it requires cutting
off the material 100 mm from the edge before sampling at the rest part
equidistant and uniformly.
4.3.3 Pre-treatment
Place the specimen under standard state of which the temperature is 23°C±2°C,
the relative humidity is 50%±5% for at least 24 h, till the test starts.
4.4 Test procedure
4.4.1 Carry out the test under the environmental conditions of which the
temperature is 10°C~30°C, the relative humidity is 15% ~ 80%.
4.4.2 The gas light is right under the specimen, at the plane of which the
vertical centerline of the specimen is vertical to specimen’s surface. The central
is rounded to the nearest whole number.
4.6 Representation of burning speed result
4.6.1 If the specimen cannot keep burning for 5s after ignition for 15 s in the
flame, or the flame burns out by itself before reaching to the first marker line,
then the burning speed shall be regarded as it fails to comply with requirements.
Both shall be represented as 0 mm/min.
4.6.2 If the specimen can burn and the flame exceeds the first marker line,
the burning speed shall be calculated according to the requirements in 4.5. The
burning speed result shall be represented as vi-actual measured value mm/min,
for example, vi-50 mm/min.
4.7 Test report
The test report shall contain the following information.
a) component name, model specification, material, manufacturer, testing
organization, test date and test person;
b) specimen quantity, specimen thickness;
c) test results. ignition time, burning time, burning distance, burning speed as
well as phenomena during combustion.
