Thermal radiation propagation tester

　　The thermal radiation propagation tester is used to test the fire reaction of rigid and soft materials, ranging from M-0 (non flammable) to M-4 (highly flammable), to determine the material's flammability index and combustion development status. The instrument cannot test melted sample materials.

　　The thermal radiation propagation tester is equipped with a 45 ° sample holder, and two starting devices are connected to a small propane gas delivery hose. The system is equipped with two butane gas test flames, one above the sample and the other below, to ignite the output gas.
