Flammability Tester, Vertivcal Burning Test
Model No. HV-EXP4388
Flammability Tester(Vertivcal Burning Test) - The method for classification of plastic sheets or bar materials of 94V-0, 94V-1, or 94V-2 grade flammability is based on the determination of vertical burning characteristics of the material under test. & In this test, a test specimen is held from its top with its longitudinal axis lying in a vertical plane. A flame is applied for a specified duration of time to the lower end of the test specimen and removed. As soon as the material stops flaming the flame is applied once again for the same duration of time and removed. The time taken by the flame to extinguish, after the removal of the igniting flame and the duration of glowing after second application of flame are determined to evaluate the vertical burning characteristic of the material under test. & The Flammability Tester (Vertical Burning Test) for determination of vertical burning characteristic of plastic consists of a drought free enclosure, an arrangement to hold the test specimen from its top in a vertical plane, a swivelable burner to apply the flame at the tip of the test specimen, arrangement to move the burner so that its tip can be brought vertically below the lower end of the test specimen both with the burner axis being vertical and inclined at an angle of 45° to the vertical, a pre-set type digital timer to measure the time of application of flame, and a digital time interval meter to measure the flaming and after glow times. &civil lab equipments manufacturers.
