- Key result
- Parameter:
- other: Thermal stability
- Remarks on result:
- other: exothermal effect below 500 J/g
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item has no explosive properties.
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 Method A.10. The thermal stability was determined by DSC measurements. Up to 500 °C no exothermal effects with an energy above 500 J/g were observed. Therefore, the main test on explosive properties was not conducted.
Reference
Two DSC-measurements in closed glass crucibles with the test item showed an endothermal effect in the temperature range of 105-140 °C and an exothermal effect in the temperature range of 370- 490 °C with a maximum energy released of 286 J/g. Above apporx. 480 °C the baseline became ambiguous due to pressure build-up.
Ident-No. | Weight / mg | Final temperature / °C | Temperature range / °C | Type of effect | Energy / J/g | |
| 10.41 | 500 | 105-140 380-460 | Endothermal Exothermal | n.r. 91 | |
| 10.52 | 500 | 110-140 370-490 | Endothermal Exothermal | n.r. 286 |
The heat of decomposition was below 500 J/g. Therefore the main test on explosive properties was not necessary.
Description of key information
The test item has no explosive properties (reference 4.14-1).
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
A study was conducted according to Regulation (EC) No 440/2008 Method A.10. The thermal stability was determined by DSC measurements. Up to 500 °C no exothermal effects with an energy above 500 J/g were observed. Therefore, the main test on explosive properties was not conducted.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on the structure of the molecule and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) 2020/1182, and UN GHS Rev 8 (2019) the test item has not to be classified with respect to explosiveness.
