Remarks on result:
negative (not further specified)
Remarks:

Thermal stability


Two DSC measurements in closed glass crucibles showed two endothermal effects in the temperature range of 295 - 330 °C. At approximately 450 °C the course of the baseline might indicate an exothermal effect (this effect was not finished at the end of the measurement). However, the rise of the baseline was relatively weak and therefore no critical exothermal reaction was assumed up to 500 °C. The measurement was terminated at 500 °C. After the measurement the test item was discoloured to brown.

The closed DSC measurements of the test item indicated an exothermal effect starting at 450 °C (this effect was not finished at the end of the measurement). However, the rise of the baseline was relatively weak and therefore no critical exothermal reaction was assumed up to 500 °C.


 


 


Explosive properties


The heat of decomposition in the DCS measurements was below 500 J/g. Therefore, the main test on explosive properties was not necessary.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item is not an explosive.
Executive summary:

The test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14. The heat of decomposition in the DSC measurements was below 500 J/g. Therefore, the main test on explosive properties was not necessary.

Description of key information

The test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A. 14.

Key value for chemical safety assessment

Explosiveness:
