LFY-640A Conveyor Belt Flame Resistance Performance Tester

Main purpose
This test uses the gas burner combustion experimental method to evaluate the reaction of conveyor belts in a fire. The experimental results are helpful for assessing the flammability of products or materials. It is applicable to fabric core conveyor belts and steel wire rope core conveyor belts.
Instrument features
Cut the sample from the conveyor belt and place it vertically in the flame for a certain period of time. After removing the gas burner, record the duration of the bright flame and the duration of the smoldering. Then, blow air onto the sample and record its re-ignition situation.
