Scope of application:
The roof combustion test system is an instrument that evaluates the fire resistance of the roof and components in the simulated real conditions and evaluates the grade A~C level of the sample at A1.82 m, B2.4m and C3.9 m. At the same time, it can be used for flame retardant performance test of photovolt battery.
Meet the standard:
The smoke detection monitor of individual residential units in multi-family homes and hotel rooms: electric signal detectors to detect the smoke status of residential buildings;
Compliance with UL 790: standard fire test method for roofing materials;
Compliance with IEC 61730-2 appendix A: photovoltaic module combustion test;
Meet ASTM E 108-04: standard fire test method for roofing material.
Main parameters:
The cylinder can easily control the slope of the deck
2 fire prevention board is attached with test deck
Use automatic control valve to adjust the temperature
- grade A, B: 760-28 ℃ (1400 + 50 ℉) - 1400 ~ 21000 Btu/min (369 ~ 387 kWh)
- grade C: 704-28 ℃ (1300 + 50 ℉) - 1300 ~ 18000 Btu/min (316 ~ 334 kWh)
Each gas transmitted to the burner must be tested and controlled in different ways
-lng: use MFM to measure air flow accurately (air flow is controlled by automatic control valve)
- LPG: use the inverter system to adjust the air flow rate: the test deck has a speed of 19 + 8 km/h(5.5 m/SEC)
Using automatic ignition method, the test can be automatically ignited at the same time
A guide board is attached to the vent line to protect the flow turbulence of the supply test deck from outside interference
A slope adjustment panel is installed in the ventilation pipeline to adjust the direction of air flow
12 top burner 58.7 mm equipped with thermocouple, can test the temperature to 888 + 28 ℃
Use DAQ system to automatically control and complete the test.
