Deflagration point
The deflagration point is an empirical, safety-related parameter for characterizing explosives . It corresponds to the temperature at which a small explosive sample shows a flame, deflagration or explosion due to external heating in the test glass. The comparability of the parameter for different substances is guaranteed by a defined test method. For this purpose, a sample of the substance to be tested of 0.5 g (with potential initial explosives of 0.01 g) is placed in a test glass, which is 2 cm deep in a heating bath, starting at 100 ° C with a heating rate of 20 K min - 1 heated. This test specification is also laid down in the rail traffic regulations.
Examples:
- Diazodinitrophenol 180-200 ° C
- Hexamethylene triperoxide diamine 200 ° C
- Copper (II) azide 203-205 ° C
- Tetryl 230 ° C
- Lead type 275 ° C
- Lead azide 340 ° C
