The Solar Cell Spread of Flame & Burning Brand Test Machine is designed and developed based on UL 1730 and IEC 61730-2 standards. This instrument simulates real conditions to assess the fire-resistant performance of roof components, evaluating specimens at A (1.82m), B (2.4m), and C (3.9m) levels. It is also used for testing the fire-retardant performance of photovoltaic components.
