TY - JOUR A1 - Knorr, Annett A1 - Krebs, Holger T1 - Testing of DNT and TNT by the mini-autoclave method JF - Propellants, explosives, pyrotechnics N2 - Autoclave methods are commonly used when pressure progress under thermal stress is of interest. One of them is the mini-autoclave method by Kühner AG. To test the robustness of the equipment under powerful exposure, two known high energetic materials, DNT and TNT, were investigated. The sample mass was increased stepwise in the range from 0.25 g to 1.0 g. For one test (1 g TNT), gas burners instead of the usually employed 2-zone heating block, were used to intensify the test conditions. Results showed the expected slower pressure generation of DNT in comparison to TNT. The mechanical robustness of the apparatus could be approved in all runs. Pressure data were used to calculate the energy release of decomposition. The values were in good agreement with the heat of decomposition, estimated by DSC.
