A Study on the Characteristics of Combustion for Car Interior Materials

We have carried out the test using the cone calorimeter and the smoke density chamber to evaluate the characteristics of the combustion for the car interior materials passed horizontal burning test. We have analysed many parameters related to fire hazard. These parameters are the ignition time, the heat release rate, the maximum average rate of heat emission, the flashover propensity and specific optical density. There was a significant difference in HRR and optical smoke density. The HRR was <TEX>$185{\sim}446kW/m^2$</TEX> and optical smoke density was <TEX>$119{\sim}1207$</TEX>. Only horizontal burning test was performed to evaluate the fire hazard for the car interior materials.
