UL790 UL 1730 ASTM E108 For Solar Cell Spread
Description:
This equipment virtually simulates an external fire to evaluate the resistance of the roof and other physical elements of fire, in order to qualify for the flame spread experiments(A~C class), in case of A 1.82m, B 2.4m and C 3.9m. It is an equipment to displacement of the testing material and the exposure and falling of the roof structure.

Each gases supplied to Burner follows up different measurement and control way.
– LNG: Using MFM, accuracy flow measurement (Flow control is controlled by Auto Control Valve)
– LPG: Using MFC, accuracy flow measurement and control.
Inverter System gives maintain Air Velocity: 19±8 km/h(5.5m/sec) on the Test Deck.
Auto ignition way is adapted for test and ignite in the same time.
Guide Plate is attached in the Air Duct because of protecting of flow turbulence which is supplied to Test Deck.
Slop adjustment panel for adjusting of Air flow direction is installed in the Air Duct.
Individual burner is installed for burning-brand test.
Thermocouple is installed on 58.7mm from top of burning-brand burner, measures for temperature as 888±28°C.
Using DAQ system be programmed to have automatic control and measurement.
