Introduction:
Cone calorimeters use the oxygen consumption concept to calculate the rate at which materials emit heat. According to the oxygen consumption principle, every unit of oxygen consumed when a substance burns produces essentially the same amount of heat.
Cone Calorimeter can measure the sample's mass loss rate, heat release rate, smoke generation rate, ignition time, oxygen consumption status, and carbon monoxide and carbon dioxide generation when the sample is exposed to a cone heater's heat source.
