Overall Seat Burning Test Device

CFR 1633 Overall Seat Burning Test Device for Judging Smoke Density Performance

Product introduction of the Overall Seat Burning Test Device

The overall seat burn test unit can be used for the performance test of rail transit seats and upholstered furniture and components by igniting the seat, mattress or its components through a standard burner or paper pad. The hood collects the flue gas generated by the combustion, and then evaluates the flame retardant performance indexes such as smoke density performance, peak heat release rate, heat release amount, and flame spread.
