Flammability Test for Automobile Interior Material
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 specified duration. 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 burn through this distance gives a measure of the flammability.

The PROLIFIC Horizontal Flammability Chamber 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 controlling the flame application time and measuring the flaming time.

The combustion chamber is made form 2 mm thick stainless steel sheet and has a 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. 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.

The test specimen holder is made from brass plates. It consists of two parts, the lower part having a slot for exposing the test specimen and pins for holding it. The upper part with corresponding holes presses down the test specimen from top over the holding pins. Lower part is also provided with string of heat resistant wire to support the test specimen.

The test flame is obtained from a standard bunsen burner fixed such that its tip is at a specified location below the test specimen. A needle valve to control the flow of gas to the burner to control the height of flame is also provided.

A pre-set type electronic timer, provided on the equipment, automatically starts as soon as the test specimen is brought in position above the Bunsen burner. It cuts off the gas supply to the burner after the pre-set time (programmable between 0 to 99 seconds) with the help of a solenoid valve. A time interval meter, which can be started and stopped manually, is provided to measure the time taken for the flame to move from the first reference point to the second reference point. Both the timers are fitted on a panel on which the combustion chamber is fixed. The panel is stove enameled to give it aesthetic appearance and long life.

A template made of brass sheet with holes for marking out test specimens of specified dimensions is also supplied with the equipment.

LPG or Butane or Natural Gas cylinder with regulator is not provided with the equipment and is to be provided by the user.
