Prolific Horizontal Flammability Tester - 2mm Thick Stainless Steel Chamber , Polycarbonate Window And Bunsen Burner Setup For Flame Propagation Testing

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 Tester 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.
