Any other information on results incl. tables

DSC curve of the first experiment: see picture below.

Exothermic decomposition started at 350°C. The extrapolated onset temperature of the effect was 358.588°C (first experiment), 363.260°C (second experiment) and 363.202°C (third experiment).

The exothermic decomposition energy was 111.17 J/g (first experiment), 137.10 J/g (second experiment) and 121.75 J/g (third experiment).

In the second experiment a higher amount of test item was applied to enhance the exothermic peak. Therefore these results were not used for the calculation of the mean values.

Mean (n=2) exothermic decomposition energy: 116.5 J/g.

Mean (n=2) onset temperature: 360.9°C.

Applicant's summary and conclusion

Interpretation of results:
other: not classified under CLP or GHS
Conclusions:
The test item has no explosive properties.



Executive summary:

The exothermic decomposition energy and onset of exothermic decomposition of the substance was determined by DSC in a GLP study. From duplicate measurements the onset of exothermic decomposition was determined to be 360.9°C and the exothermic decomposition energy was determined to be 116.5 J/g. Because the exothermic decomposition energy of the substance is < 500 J/g and the onset of exothermic decomposition is < 500°C, the acceptance procedure for Class 1 explosives do not have to be applied accoring to the UN Manual of Tests and Criteria, Appendix 6 "Screening procedures" -Screening procedures for substances which may have explosive properties. The substance has no explosive properties.
