Results and discussion
Small-scale preliminary tests
- Parameter:
- other: Heat of decomposition
- Value:
- 72
- Remarks on result:
- other: J/g
Any other information on results incl. tables
The thermogram shows a sharp endothermic peak at about 130 °C, which is attributed to melting, followed by a small exothermic peak from 176 - 256 °C. The total normalized energy output from the exothermic peak, i.e. the heat of decomposition, is 72 J/g.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance is not classified as an explosive substance.
- Executive summary:
The procedures for the determination of the explosive properties of a substance are described in UN Test Series 1 - 8. However, in accordance with Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Sixth Revised Edition, 2015, the classification scheme need not be applied if the exothermic decomposition energy is less than 500 J/g. Differential scanning calorimetry (DSC) measurements were performed in high pressure, gold-plated stainless steel crucibles (40 μL volume) with nitrogen as purge gas (flow rate 50 to 100 mL/min) over a temperature range from 25 to 500 °C, with a heating rate of 5 °C/minute. The total heat of decomposition of the test substance has been determined as 72 J/g.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
