6810 cone calorimeter Introduction: It can objectively evaluate the combustion performance of materials in real fires. In 1982, BARAUSKAS et al. developed a cone calorimeter (cone), an advanced test instrument. Cone's combustion environment is very similar to the real combustion environment. There is a good correlation between the test results and the results of large-scale combustion tests. It can express the combustion performance of materials and is important in evaluating materials, material design and fire prevention. Reference value. After continuous development and improvement, cone has now become an ideal test instrument for studying fire and evaluating the combustion properties of materials.
