Flammability testers are very much known for testing the flammability and also the resistance to prorogation of flame or materials which are used in the interiors of motor vehicles as the apparatus also determines the comparative burn rates of cloth which also includes pile and napped cloth. Some of the special features of these flammability testers are that there is polycarbonate window in the flame chamber used for observing the test specimen during test and also there is a bunsen burner for providing flame. The instruments also has pre set type electronic timer which starts automatically as soon as the specimen is brought in position which is above the bunsen burner.Types of flammability testers are vertical flammability testers which are known because of its characteristics as it makes use of microcomputer control along with wide screen lcd display and also offers standardized quality. These testers are used for testing trend of after flame, flame retardant and carbonization of textiles. The other type is called as plastic flammability testers which are known for the following features as these are equipped with temperature detecting systems which includes temperature copper block and has high quality k type thermocouple and also these testers are very much equipped with single meter and pressure regulator which is known as automatic igniter. Other features of these testers are that the high degree of automation control system along with an automatic igniting function is tested specimen for horizontal and vertical directions. It records afterglow time during horizontal testing. The important aspect for this type of tester is that it is used for determining the flammability property of plastics and can cause coal gas or liquefied petroleum gas as gas sources.
These flammability testers consist of a vertical sheet metal cabinet which is closed on three sides of which the one is top and bottom and the front side is kept open for the insertion of the test specimen and this test specimen is suspended from a clip such that it hangs freely in the centre of the cabinet.
