Description
*5 degree Automatic
Flammability Tester
The specimen rack
provides support for the holders in which the specimens are
mounted. Its angle of inclination is **0. The rack can
be moved sideways to enable fabrics of different thickness to be
set at the specified distance from the tip of the jet with the help
of an adjusting screw. A built-in finger is provided to gauge
this distance for setting it to the desired
value.
The Specimen holder
consists of two matched stainless steel U shaped plates between
which the test specimen can be held. The specimen holder sits
over the specimen rack in a precisely determined position **0
inclination and is so positioned that the igniting flame strikes
the specimen centrally and 6 mm above the bottom edge perpendicular
to the face of the test specimen. Five such specimens holders
are provided with the equipment.
The ignition
arrangement comprises of a jet mounted on a extension of the shaft
of a syncroset motor such that it can be rotated into a position
perpendicular to the surface of the fabric. The distance
between the tip of the jet and the surface of the burner can be
adjusted to 8 mm. When the tip of the jet is moved away from
the specimen, the jet becomes vertical. The flame is produced
at the tip of the jet by LPG Gas. The length of the flame is
set to *6 mm when the jet is vertical with the help of a control
valve and is measured with the help of built in gauge
rod.
