ISO340 : 2004 Fabric Core Conveyor Belt Vertical Combustion Tester

Conveyor Belt Vertical Combustion Tester

Test principle:
The sample placed vertically under the specified flame condition is ignited with a small flame ignition source. After the flame is removed, the combustion performance of the sample is comprehensively evaluated by measuring the time of continuous burning and blazing fire and the air blast of the sample 60 seconds after the flame is removed, observing the combustion behavior and measuring the time of continuous burning.
Summary: this equipment uses the test method of small scale flame (gas burner/alcohol burner) to evaluate the reaction of conveyor belt in fire, and is applicable to the combustion performance evaluation of textile core conveyor belt and steel wire core conveyor belt.It is also suitable for testing the resistance to spread combustion of plastics and its plastic parts under the condition of flame combustion.

Application:
The combustion test instrument of conveyor belt is applicable to the combustion performance test of textile core conveyor belt and steel wire rope core conveyor belt used in chemical, coal, metallurgy and electric power industries.It is used to evaluate the response of conveyor belts in fire.
