Results and discussion
Small-scale preliminary tests
- Key result
- Parameter:
- other: A differential scanning calorimetry (DSC) was performed under nitrogen.
- Remarks on result:
- other: The heat of decomposition was above the threshold value of 500 J/g. However, the exothermal effect in the DSC measurements was a very broad peak. This suggests rather a slow decomposition than a violent reaction.
Any other information on results incl. tables
Two DSC measurements in closed glass crucibles with the test item showed an endothermal effect in the temperature range of 60-85 °C and two exothermal effects. The first exothermal effect occurred in the temperature range of 135-185 °C with a maximum energy release of 36 J/g. The second exothermal effect in the temperature range of 380-480 °C showed a maximum energy release of 694 J/g. However, the exothermal effect in the DSC measurements was a very broad peak. This suggests rather a slow decomposition than a violent reaction. Therefore, the test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Executive summary:
The test item had no explosive properties in the sense of the European Commission Regulation (EC) No 440/20078, Methode A.14.
