Test principle
The cone calorimeter is based on the principle of oxygen consumption and uses the principle of oxygen consumption to measure the heat release rate of materials. The so-called oxygen consumption principle is: the heat released by each unit of oxygen consumed when the material is burned is basically the same, and the measured value is 13.1MJ/kg±5%. In the experiment, we can load the sample on the load cell to measure the mass loss rate of the sample during the combustion process; heat the sample and ignite it by electric spark to test its flammability and ignition time; collect the combustion gas in the accompanying pipe And in the exhaust hood, the heat release rate and other indicators are automatically tested by collecting the flue gas pressure difference, gas concentration and temperature changes; the optical device can be used to measure the smoke density performance parameters; at the same time, the above data can be obtained. Effective combustion heat, specific extinction area and other extended data. The cone calorimeter test is a safe, fast and accurate detection method. In addition to product development, the cone calorimeter can also be used as a quality control tool.
