UL 790 Flame & Burning Brand Materials Test Equipment for Solar
Cell Spread
Introduction:
The roof combustion test system is an instrument for simulates real
conditions to assess the fire resistance of roofs and components.
Under this circumsance of A1.82m, B 2.4m and C 3.9m to grade A~C
grade for evaluating the sample. At the same time, it can be
applied to the test of the flame retardancy of the photovoltaic
cell components.
Stadards:
-ASTM E 108
-UL790
-NFPA 256
-IEC 61730-2
Main feature:
1) Plywood roof covering material, size: 1, 300 (W) × 1, 000 (D) ×
120 (H), used for the installation of test samples
2) A non flammable test board that installed at the end of the test
board can prevent the backfire from under the test board.
3) Stainless steel sectoral adjustment plate, adjustable test
angle, dimensions: 1, 440(L) X 940(H) mm
4) The main frame is used to support the test support,
corrosion-resistant steel structure, size: 1, 020(L) X 1, 000(D) X
1, 473(H) mm
5) Noncombustible board assembly mounted on the front end of the
frame simulated eaves and cornices and the flame from burner to
extend the sample, the size is: 330 (W) X 2130 (D) X 584 (H) mm.
6) The air flow rate of the test panel is 19 ± 8 km/h (5.5m/sec)
and configured the anemometer monitoring.
7) The independent ventiduct can extract air from the outside of
the laboratory.
8) The air duct is equipped with a honeycomb filter and a gas inlet
to install the guide leaf.
9) The adjustable turbulence sheet in a duct that strengthens wind
speed and reduces turbulence, and be made of stainless steel. It
will not change position with changes in wind pressure.
10) The air duct material is made of stainless steel,
anti-corrosion and high temperature resistance, and the size is: 2,
130(W) X 762(H) X 3, 000(L) mm
11)The fan is 220V, 50Hz, three-phase, equipped with a reverse
system can automatically adjust the wind speed, the minimum flow
rate is 300m3/min.
12) Inverter with stepless variable speed function, adjustable from
0-100%
13)Gas burners (for intermittent fire, flame propagation and
fly-fire tests), 1.12m long, 60.3mm diameter, with a 12.7mm wide
and 0.91m long slit on one side towards the test plate
14) The gas burner can provide 22, 000BTU/min (387kWh), and can
automatically adjust the gas flow rate according to the three
combustion levels A, B and C
15) Auto-ignition system, to ensure the safety performance of the
test, the minimum pressure of the ignition electrode is 1.8kVp Mass
flowmeter controls the gas flow rate according to different
standards, Class A & B: 21, 000 ~ 22, 000 BTU/min (369 ~ 387 kWh)
10 minutes, Class C: 18, 000 ~ 19, 000 BTU/min (316 ~ 334 kWh) 4
minutes
16) Data Acquisition System, written in LabView programming
language, data acquisition board provided for NI
17) The data acquisition system contains the following parts:
1.16-bit thermocouple input module
2.16-bit analog-digital conversion input modul
3. Data input and output module
4.12-bit modulus conversion output module
5.4 and 8 trough backplane
6. Labview Time Module
7. Labview Hour/Ethernet Module
18) Computer Systems
19) Capable of swallowing the burning material and the gas burner
temperature can be adjusted to 880± 10 C
20) The metal mesh can support the material and the tray is
rotatable to facilitate the full combustion of material.
