AC / DC Power Flooring Radiant Panel Test With Alarm Display
This standard specifies test apparatus and test methods for the
evaluation of flame spread, heat release and smoke generation
characteristics of vertically installed bunched wire or cable or
cable under specified test conditions. During the test, the cables
or cables were installed on the vertical standard ladder, and the
burning behavior and combustion performance of the cable were
evaluated by using the specified ignition source. The combustion
data of the early stage of the cable fire was obtained through the
test. The heat release rate The test reflects the risk of fire
spreading along the cable and the potential impact of the fire
source on adjacent areas. The smoke density test shows the
visibility of the fire area and the dangers posed to the personal
safety of the flue gas. (FSR), heat release rate (HRR), total heat
release (THR), smoke generation rate (SPR), total smoke production
(TSP), combustion growth of cable or cable under specific
combustion conditions Rate index (FIGRA), and combustion of the
drip / micro materials and other characteristics.
GB / T 31248-2014 Cable or fiber optic cable under fire conditions,
flame spread, heat release and smoke characteristics.
1. Advanced industrial appearance and control design
2. Combustor structure: steel combustion chamber, the inner wall of
stainless steel plate, the outer wall of A3 steel paint, filled
with mineral wool insulation, equipped with steel ladder to the top
of the combustion chamber, and installed in the top of the room
steel bar, to facilitate the room Maintain equipment and improve
3. By the axial fan to provide air supply, and by the inverter
control of air supply.
4. Stainless steel smoking hood and exhaust pipe (diameter 400mm),
beautiful corrosion resistance.
5. Using two-way probe differential pressure measurement device,
import differential pressure sensor, the range is 0 ~ 500Pa.
6. K-type thermocouple with a diameter of 1.5mm.
7. The sample line is equipped with a three-stage filtration system
to ensure clean sample gas flow to the analyzer and a
flow-restricting and diverting device to ensure sample gas flow
into the analyzer to improve the analyzer's accuracy and service
8. The ignition source consists of an imported ribbon type propane
gas burner and an imported venturi mixer. The fire surface should
be a flat metal plate with 242 diameters of 1.32mm diameter, one on
each side of the fire board Row of holes, these guide holes can
maintain a stable flame combustion.
9. MFC (mass flow controller) can be used to control the propane
gas flow, higher accuracy.
10. The use of adjustable light source system and the use of
imported silicon optical amplifier optical receiver system; data
stable and accurate, and is equipped with fully automatic control
of the seven filter correction mechanism, the optical path of
11. Gas analyzer can accurately measure the gas in the O2, CO2
concentration, resolution of 0.01%.
12. By the inverter control pipe fan to adjust the volume of smoke
exhaust pipe flow.
13.19 inch standard cabinet + computer control.
14. PC + Labview professional software control.
(HRR), total heat release (THR), smoke production rate (SPR), total
smoke production (TSP), combustion growth rate index (FIGRA) were
calculated automatically, and the results of real- Parameter curve.
16. Alarm display function.
17. Control box with USB / RS232 serial port, can be external
desktop / notebook computer operation and control.
