Application:
Cone Calorimeter measures the heat release rate of materials based on the principle of oxygen consumption.
The principle of oxygen consumption is that the heat released by each unit of oxygen consumed when the material is burned is basically the same.
When test sample is exposed to heat source of cone heater, Cone Calorimeter can measure the heat release rate, smoke generation rate, ignition time, oxygen consumption status, carbon monoxide, carbon dioxide generation and mass loss rate of the sample.
