Any other information on results incl. tables

Notes from the test report: “The sample was observed to undergo an endothermic event from -22.0°C (4.2 J.g-1). An exothermic event was then observed to commence from 125.1°C which had a heat of decomposition of -262.4 J.g-1. No further significant energetic events were noted up to 400°C.”

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The sample was observed to undergo an endothermic event from -22.0°C (4.2 J.g-1). An exothermic event was then observed to commence from 125.1°C which had a heat of decomposition of -262.4 J.g-1. No further significant energetic events were noted up to 400°C.
The exothermic decomposition is less than 500 J per g (Regulation (EC) 1272/2008, Annex I, Part 2, 2.1.4.3 (c)), so the material is not explosive, and it is less than 300 J per g (Regulation (EC) 1272/2008, Annex I, Part 2, 2.8.2.1) so it is not self-reactive.
The flash point is >80 oC. The DSC trace shows no dangerous events when heating to 140 oC.
