摘要：A calorimeter for measuring flammability parameters of materials using only milligram sample quantities. The thermochemical and thermophysical processes associated with the flaming combustion of solids are reproduced in the device through rapid anaerobic pyrolysis in a thermogravimetric analyzer. Volatile anaerobic thermal decomposition products are swept from the pyrolysis chamber by an inert gas and combined with excess oxygen in a combustion chamber maintained at several hundred degrees Centigrade to simulate the combustion reactions which occur in a well ventilated diffusion flame. Mass loss is measured continuously during the process and heat release rate is calculated from the oxygen consumed from the gas stream.
