LS-FAA25F Vertical Bunsen Burner Test System for Aircraft Cabin and Cargo Compartment Materials

The LS-FAA25F Vertical Bunsen Burner Test System for Aircraft Cabin and Cargo Compartment Materials simulates the initial combustion environment of an aircraft cabin fire. A standardized sample of interior material is vertically mounted and subjected to controlled ignition using a calibrated Bunsen burner to quantitatively evaluate material flame-retardant properties. The LS-FAA25F system automatically records critical combustion parameters including burn time, flame propagation rate, and drip ignition characteristics to determine compliance with applicable vertical flammability standards. This test apparatus is designed for flame-retardant performance evaluation of various interior materials used in aerospace, marine, and automotive applications, including seat fabrics, interior panels, carpeting, and cushioning materials.
