Flammability Tester
Resistance to propagation of flame of materials used in the interiors
of motor vehicles is determined by finding the horizontal burning rate
of a test specimen taken from the material under test after application
of a standard flame at one end for a period of fifteen seconds. The test
specimen is held horizontally in a U-shaped holder inside a combustion
chamber and flame from a Bunsen burner applied at its end. The ratio of
the burnt distance and time taken to bum through this distance gives a
measure of the flammability.
The GLOBE Flammability Tester for
automobile interior materials consists of a combustion chamber in which
the test is conducted, a test specimen holder in which the test specimen
is mounted during the test, a standard Bunsen burner to provide the
flame, and a set of timers for timing the flame application time and
flaming time.
The combustion chamber is made form 2 mm thick
stainless steel sheet and has a glass / polycarbonate window for
observing the test specimen during the test. It has a set of ten vent
holes of 19 mm diameter on its bottom and a vent slot of 15 mm width on
all the four sides at its top. It is also provided with a channel for
sliding in the test specimen holder. The chamber is placed on four 10 mm
high legs.
The test specimen holder is made from brass plate
and is in two parts, the lower part having a slot for exposing the test
specimen, and an upper plate with corresponding holes to press down the
test specimen from top over the holding pins. An arrangement to string a
heat resistant wire on the lower frame for providing support to the
test specimen is also provided.
The test flame is obtained from
a standard Bunsen burner fixed such that its tip is at a specified
location below the test specimen. An arrangement to control the flow of
gas to the burner to control the height of flame is also provided. A
collection pan is provided below the test specimen holder to collect the
products of combustion. The pan can be moved from outside of the
combustion chamber. A thermometer is also provided to measure the
temperature of the chamber.
A pre:set electronic timer
automatically starts as soon as the test specimen is brought in position
above the Bunsen burner and also cuts off the gas supply to the burner
after a set period of time. Another timer which can be started and
stopped manually records the time taken for the flame to move from the
first reference point to the second reference point.
