- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- GLP compliance:
- no
- Key result
- Parameter:
- other: Thermal stability
- Remarks on result:
- other: heat of decomposition below 500 J/g
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item is not 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.
Reference
Thermal stability
A first DSC-measurement in a closed glass crucible with the test item showed two endothermal effects in the temperature range of 100 - 115 °C and 130 - 175 °C and an exothermal effect in the temperature range of 355 - 485 °C with an energy release of 278 J/g.
A second DSC-measurement in a closed glass crucible with the test item showed two endothermal effects in the temperature range of 100 - 115 °C and 130 - 150 °C and two exothermal effects. The first exothermal effect occurred in the temperature range of 210 - 240 °C with an energy release of 48 J/g. The second exothermal effect in the temperature range of 340 - 435 °C showed an energy release of 137 J/g.
Table: Thermal stability (DSC measurements)
Ident-No. | Weigth/mg | Final temperature / °C | Temperature range / °C | Type of effect | Energy / J/g |
36330 | 9.63 | 500 | 100 - 115 130 - 175 355 - 485 | Endothermal Endothermal Exothermal | n.r. n.r. 278 |
36335 | 10.34 | 500 | 100 – 115 130 – 150 210 – 240 340 – 435 | Endothermal Endothermal Exothermal Exothermal | n.r. n.r. 48 137 |
The test item showed exothermal effects starting at 140 °C with an energy of up to 367 J/g in closed
DSC measurements.
Explosive properties
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 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:
- non explosive
Additional information
Justification for classification or non-classification
Based on the result, the substance is not considered to be classified for explosiveness according to Classification, Labelling, and Packaging Regulation (EC) No 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
