Cone Calorimeter
According to
ISO 5660, BS 476-15,ASTM E1354, ASTM E1474; ASTM E1740; ASTM F1550; ASTM D6113; CAN ULC 135
The Cone Calorimeter measures the heat release rate of materials on the principle of oxygen consumption. The principle of oxygen consumption is that a material burns with roughly the same amount of heat for each unit of oxygen consumed. When the sample is exposed to the heat source of the conical heater, the conical calorimeter can measure the heat release rate, smoke generation rate, ignition time, oxygen consumption, carbon monoxide, carbon dioxide generation and mass loss rate of the sample.
Cone Calorimeter consists of
