UL790 UL 1730 Roof Covering Materials IEC 61730-2 Solar Panel PV Module Components Fire Tester

Roof Covering Materials Solar Panel PV Module Components Fire Tester Product Introduction:

The roof burning test system is designed and developed according to the requirements of UL 1730 and IEC 61730-2. It is an instrument for evaluating the fire resistance of roofs and components under simulated real conditions. It evaluates the grade of the sample A~C under the conditions of A1.82m, B 2.4m and C 3.9m. It can also be used for the flame retardant performance test of photovoltaic cell components.
