The fire test chamber is exactly the same as that of UL fire lab.
The fire test chamber is a rectangular horizontal duct with a
removable lid.
The sides and base of the chamber are lined with an insulating
firebrick.
One side of the fire testing chamber is provided with double
quartz observation windows with the inside pane flush mounted.
Multiple windows are located along the tunnel so that the entire
length of the test sample is observable from outside the fire
chamber.
The lid is consist of a removable noncombustible metal and mineral
composite structure.
The lid covers the fire test chamber and the test samples
maintains in an unwarped and flat condition.
Two NFP elbow gas burners delivering flames upward against the
surface of the test samples.
Remote spark ignition mode, to ensure the safety.
An air intake shutter is located upstream of the burner.
Six refractory firebricks along the side walls of the chamber for
proper combustion.
The static pressure meter inserted through the top at the midwidth
of the tunnel below the ceiling.
The exhaust end is fitted with a gradual rectangular-to-round
transition piece.
The exhaust duct is insulated with high temperature mineral
composition material.
An exhaust fan is installed at the end of the exhaust duct.
The air flow and draft pressure are controlled by automatically
damper and Frequency converter.
A photometer system consisting of a lamp and photocell mounted on
a horizontal section, and with
the light beam directed upward along the vertical axis of the vent
pipe.
Thermocouples installed inside and outside the floor of the test
chamber.
Data acquisition system and software.
