Heat Release Rate Comparison of Electric motor car's Interior panels

Experimental comparison was done for measuring Heat Release Rate and Smoke Production Rate of electric motor car's interior panels using cone calorimeter. Radiative heat flux of $50kW/m^2$ was used to simulate the condition of fully developed fire case in the tests. It was observed that Heat Release Rate and Smoke Production Rate curves were shown differently according to interior materials. From experiment's results we can deduce that materials having higher rate of heat release smolder more smoke. It needs to establish fire risk propensity of each material and to set up the standards urgently.
