This Surface Spread Flame Test Equipment consists of a radiation
panel mounted vertically in a surround and supported on a
framework.
The radiation panel is sullied with an gas-air mixture.
The radiation panel is 850mm square for a porous refractory type
burner block designed to give efficient combustion of the
air-gas-air mixture, with no flaming occurring on the face of the
panel under operational conditions.
The radiation panel and its surround are supported on a framework
so that the center of the panel is about 1250±100mm above floor
level.
A specimen holder and a pilot flame arrangement mounted to one
side of the Surface Spread Flame Test Equipment.
The specimen holder is comprise a water-cooled steel frame with
water-cooled face plates. The face plates is overlap the specimens
by 20±2mm on their top and bottom edges and over the vertical edge
adjacent to the radiation panel.
A spring loaded clamp is positioned to clamp the specimen against
the face plates.
The portable water supply to the specimen holder make the maximum
temperature does not exceed 35℃ at the outlet from the specimen
holder.
The specimen holder assembly is located at 90±2° to the face of
the radiation panel and in such as way that the faces of the top
and bottom guides of the specimen holder are in the same plane as
the inside face of the surround to the radiation panel.
The height of the specimen holder is hinged to allow it to be
swung horizontally, away from the face of the radiation panel
between tests, from the test position to the standby position and
vice-versa.
The pilot burner is consist of a steel tube.
The gas and air supply lines to the radiation panel contain flow
meters, pressure regulators, control valves and safety devices.
Heat Flux Meter: Range : 0 ~ 50 kw/m2; Surface emissivity
:ɛ=0.95±0.05.
Dummy calibration board with holder, calibrated heat flux meter
and mounting.
