None of the test tubes showed a deformation. From this it is concluded that the test substance is not explosive when exposed to thermal stress.

Mechanical sensitivity with respect to shock

Exposing the test substance to mechanical stress by shock resulted in the formation of a solid pellet of the test substance. No traces of vigorous reaction were observed. From this, it was concluded that the test substance does not react under mechanical stress by shock.

Mechanical sensitivity with respect to friction

Exposing the test substance to mechanical stress by friction resulted in decomposition of the test substance. The test substance decomposed into a brown residue, probably caused by the released heat coming from the friction between the 2 porcelain surfaces.

During the test performance, no fire, sparks, smoke or crepitation was observed. From this it was concluded that the test substance does react under mechanical stress by friction, but has not to be seen as explosive.

Applicant's summary and conclusion

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
The explosive properties of the substance were assessed in a thermal sensitivity test, in a test for mechanical stress by shock and in a test for mechanical stress by friction, in accordance with EU Method A.14 (1984) and according to GLP principles. In neither test, the substance was found to possess any explosive properties. In addition, the molecular structures of the constituents of the substance do not contain chemical groups which are associated with explosive properties. From this evidence, it is concluded that the substance has no explosive properties.
