a
P-HRR: under the preset incident heat flux intensity, the maximum value of heat release rate per unit area after the material is ignited.
b
THR: the sum of the heat released by the material from ignition to flame extinction under the preset incident heat flow intensity.
c
EHC: the ratio of measured heat release rate to mass loss rate at a certain time reflects the combustion degree of volatile gas in gas phase flame.
d
P-SPR: the maximum value of specific extinction area (SEA) to mass loss rate (MLR).
