Solar Cell Spread of Flame & Burning Brand Test Machine， IEC 61730
Productintroduction:
This apparatus is based on UL 1730. IEC 61730-2 design and development. Is to simulate real conditions to assess roof and components of fire-resistant performance of the instrument, in A1.82m, b 2.4mandc 3.9m specimens to evaluate A~C level. Also can be used infire-retardantperformance of photovoltaic components used in this test.
