ISO5660 flame resistant Cone Calorimeter for Building Material
the introduction of cone calorimeter:
ISO5660 flame resistant Cone Calorimeter for Building Material was developed in 1982 by v. Babrauskas et al. Of NIST in the United States. It is a material combustion performance test instrument based on the principle of oxygen consumption.
Based on the oxygen consumption principle, the cone calorimeter measures the heat release rate of the material by using the oxygen consumption principle.The so-called oxygen consumption principle is: when the material burns, the amount of heat released by consuming each unit of oxygen is basically the same, and the measured value is 13.1MJ/kg±5%.In the experiment, we can load the sample on the load unit and measure the mass loss rate of the sample in the combustion process.The flammability and ignition time can be tested by heating the sample and igniting it by electric spark ignition.The combustion gas is collected in the attached pipe and exhaust hood, and the heat release rate is automatically tested by collecting the changes of smoke pressure difference, gas concentration and temperature.The smoke density performance parameters can be measured by optical device.Meanwhile, through the above data, the effective combustion heat, specific extinction area and other extended data can be obtained.Cone calorimeter testing is a safe, fast and accurate testing method. In addition to product development, cone calorimeter can also be used as a quality control tool.
