Flammability Tester For Testing Lab Description and Specifications for Lab Tenders
Flammability Tester For Testing Lab Workshop.
Flammability Tester - For Testing Lab
In most of the applications it is important to use cables which
retard flame in case of fire, and are self extinguishing when the source
of fire is removed. This determination is carried out by subjecting a
portion of finished cable to a flammability test. This test is conducted
with the help of a flammability tester under In this test, the test
specimen is suspended vertically inside a drought proof enclosure and
ignited with the help of either one or two burners. The time for
extinguishing of flame after shutting off the burners and the length of
scorched portion are determined and compared against specified values to
evaluate the flammability of the cable.
The Flammability Tester
for cables consists of a three-sided metal enclosure having an open
front and closed top and bottom. The base is covered with a sheet of
asbestos. The test specimen is help vertically in the centre of the
enclosure in two clamps, each approximately 25 mm wide. The clamps are
positioned such that the distance between the top of the bottom clamp
and bottom of the top clamp is as specified.
Three gas burners
inclined at angles of 45° are provided, one for testing cables up to 50
mm diameter and the other two for testing cables of above 50 mm
diameter. Each burner has an individual control valve with which the
flame can be regulated. A ball valve is provided to stop the flow of gas
to the apparatus completely.
The equipment is finished in shore Blue metallic painting and bright chrome plating for giving it a corrosion resistant finish.
