Thermal Radiation Flame Propagation Tester

The instrument can be more than 5mm thickness of the rigid and flexible materials for performance evaluation, according to the French building materials and railway vehicle flame retardant test standard NF P92-501.
The principle of the test is to carry out the heat radiation effect of 30KW / m2 on the specimen, which may cause the sample to volatilize the flammable gas and cause the combustion of the volatile gas, and observe the flame spread state, which can be used for the combustion of the material Estimated release of calorie data.
