The present invention relates to a cone-calorimeter having a sample stand capable of observing a boundary of a sample and changes in internal structure. In accordance with a specific structure securing transparency is applied to a sample stand of a combustion unit where the sample for a test is held in the cone-calorimeter, the present invention enables a user to observe changes in a material in accordance with testing time through an image measurement device. Moreover, the present invention is capable of obtaining data such as a dynamic volume and the changes in an internal structure in accordance with combustion of the sample and the rear temperature of the sample using a recording device capable of measuring the changes in the temperature of the sample in accordance with combustion. To this end, according to the present invention, the cone-calorimeter comprises: a combustion unit performing ignition and heating with respect to the predetermined sample for the test installed in the sample stand; an exhaust unit exhausting heat and a gas during combustion of the sample; and a control unit controlling the combustion unit and the exhaust unit and measuring and storing various types of data in accordance with the test of the sample.;COPYRIGHT KIPO 2015
