UL790 Roof Covering Combustion Performance Fire Resistance Testing Machine
The roof burning test system is an apparatus that evaluates the fire resistance of roofs and modules under simulated real conditions. The grades A to C of the test specimens are evaluated at A1.82m, B 2.4m and C 3.9m. At the same time can be applied to the test of the flame retardant properties of photovoltaic modules.
