GB/T 16412-2009 stipulates the flammability test method of propane single combustion device for conveyor belts. It describes the test principle of simulating fire source with propane single combustion device, specifies the test device, including the specifications of combustion device, gas source requirements, etc., and specifies the selection, preparation and Installation method of conveyor belt samples in detail. Standardize the test process, such as the ignition time of the combustion device, the position and duration of the flame action, and observe and record the combustion reaction of the conveyor belt. The standard provides a unified test method for the production and use of conveyor belts, helps to evaluate their flammability, guarantees fire safety in industrial transportation scenarios, and promotes the upgrading of conveyor belt product safety performance.
