Flammability Tester (Horizontal Burning Test) For Testing Lab Description and Specifications for Lab Tenders
Flammability Tester (Horizontal Burning Test) For Testing Lab Workshop.
Flammability Tester (Horizontal Burning Test) -
The method for classification of plastic sheets or bar materials as
94HB grade flammability is based on the determination of horizontal
burning characteristics of the material under test.
In
this test, a bar specimen is held at one end with its longitudinal axis
lying in a horizontal plane. A flame is applied to its free end for a
specified duration of time and removed. Time and extent of burning are
measured to evaluate the horizontal burning characteristic of the
material under test.
TheFlammability Tester (Horizontal Burning Test) for
determination of horizontal burning characteristic of plastic consists
of a drought free enclosure, an arrangement to hold a 127 mm square wire
gauge and the test specimen from one end with its longitudinal axis
lying in a horizontal plane and its traverse axis inclined at 45°, a
burner to apply the flame at the tip of the test specimen, arrangement
to incline the burner to 45° and to move it so that its tip can be
brought vertically below the free end of the test specimen, a pre-set
type digital timer to measure the time of application of flame, and a
digital time interval meter to measure the flaming times.
