Results and discussion
Small-scale preliminary tests
- Parameter:
- other: Thermal stability (DSC)
- Value:
- 500
- Remarks on result:
- other: The heat of decomposition was below 500 JIg.
Results of test series for explosives
- Test series:
- other: decomposition energy is below 500 J/g a main test for explosive properties is unnecessary
- Method:
- other: decomposition energy is below 500 J/g a main test for explosive properties is unnecessary
- Parameter:
- other: n/a
- Result:
- other: The heat of decomposition was below 500 J/g. Therefore the test on explosion properties was not necessary.
- Remarks on result:
- neither a test for propagation of detonation nor a test for sensitivity to detonative shock is required because the exothermic decomposition energy of the organic substance is less than 800 J/g
Any other information on results incl. tables
Thermal Stability (DSC)
The DSC-measurement in the closed glass crucible showed neither an endothermic effect nor an exothermal effect up to the maximum test temperature of 300 cC. Due to the high pressure in the
crucible caused by the evaporation of the test item accompanied with the risk of the burst of the crucible the measurement could not be carried out up to 500 cC, it had to be stopped at 300 cC.
An additional run in a closed stainless steel crucible was performed. The measurement showed neither an endothermic effect nor an exothermal effect up to the maximum test temperature of 500 cC.
Explosive Properties
The heat of decomposition was below 500 J/g. Therefore the test on explosion properties was not necessary.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item has no danger of explosion according to the explosive properties in the sense of the consolidated version of Council Directive 67/548/EEC Annex V, A.14.
- Executive summary:
The heat of decomposition was below 500 J/g. Therefore the test on explosion properties was not necessary. The test item has no danger of explosion according to the explosive properties in the sense of the consolidated version of Council Directive 67/548/EEC Annex V, A.14.
