Cone calorimeter was developed by V. Babrauskas et al. of NIST in 1982. It is a material combustion performance test instrument based on oxygen consumption principle. After more than 30 years of continuous improvement and improvement, cone calorimeter has become one of the most important test instruments for studying material combustion performance.
Cone Calorimeter measures heat release rate(H.R.R), smoke release, ignition time, oxygen consumption, carbon monoxide and carbon dioxide generation and mass loss rate when specimen is exposed to resource of conical heater.
The cone calorimeter is based on the principle of oxygen consumption. The principle of oxygen consumption is used to measure the heat release rate of materials. The so-called oxygen consumption principle is that the heat released by each unit of oxygen consumed during combustion is basically the same, and the value is measured to be 13.1MJ/kg+5%. In the experiment, we can load the sample on the load unit to measure the mass loss rate of the sample in the combustion process; heat the sample and ignite it by spark ignition to test its flammability and ignition time; collect the combustion gas in the attached pipe and exhaust hood by collecting the gas pressure difference, gas concentration and temperature. By using optical device, the smoke density performance parameters can be measured. At the same time, the extended data such as combustion heat and specific extinction area can be obtained through the above data acquisition. Cone calorimeter test is a safe, fast and accurate detection method. In addition to product development, cone calorimeter can also be used as a quality control tool.
