Smoke density comparison for composite and single materials of train seat

Due to the damage which is caused by with the smoke, in the analysis statistics of a fire accident smoke is becoming the important evaluation index of fire quality. We must follow the procedures to use interior material for railway car as stated the Safety regulation for the urban railway car. In this study, we compared the Smoke Density of the train seat by test between Cone-Calorimeter and Smoke Density-Chamber. The results showed that the smoke density by test between Cone-Calorimeter and Smoke Density-Chamber is visible a similar tendency.
