Conveyor Vertical Flame Resistance Testing Machine / Fire Testing Chamber for ISO340 Standard
The sample placed vertically in the specified flame conditions is ignited with a small flame ignition source. After the flame is removed, it is measured by holding the open flame and burning and burning time, and after the flame is removed for 60 seconds, the sample is blown. , Observe the combustion behavior and measure the duration of the continuous burning to comprehensively evaluate the combustion performance of the sample.
Overview: This equipment uses a small-scale flame (gas burner/alcohol torch) test method to evaluate the reaction of the conveyor belt in a fire, and is suitable for the evaluation of the combustion performance of the textile core conveyor belt and the steel wire core conveyor belt. At the same time, it is also suitable for testing the propagation resistance of plastic and its plastic parts under the flame burning condition. The vertical combustion behavior of the sample is evaluated by measuring the afterflame, the combustion range and the dripping of the burning particles.
Scope of application:
Conveyor belt flammability test equipment is applicable to the combustion performance test of fabric core conveyor belt and steel cord conveyor belt used in chemical, coal, metallurgy and electric power industries. It is used to evaluate the reaction of conveyor belts in a fire.
