Alcohol Burner Flame Resistance Tester
The Alcohol Burner Flame Resistance Tester is designed to evaluate the flame resistance and fire behavior of materials and products used in coal mining and conveyor systems. By applying a standardized alcohol flame source under controlled conditions, the instrument quantitatively assesses burning time, afterflame time, afterglow time, and flame propagation characteristics. These results are critical for verifying compliance with safety regulations for underground mining environments, where fire prevention and flame retardancy are essential for personnel safety and operational reliability.
Applications
The instrument is used for flame resistance testing of materials and products including but not limited to:
Conveyor rollers and idlers
Flame-retardant conveyor belts
Steel cord conveyor belts for coal mines
Solid woven conveyor belts for underground mining
Polymer products for underground coal mines
Plastic pipes for underground coal mines
Rubber hoses for underground coal mines
Hydraulic support hoses and hose assemblies
Steel wire rope traction conveyor belts
Rubber buffer idlers for belt conveyors
Plastic false roof belts and plastic mesh products
