Any other information on results incl. tables

Two DSC measurements in closed glass crucibles showed an exothermal effect in the temperature range of 105 – 185 °C, an endothermal effect in the temperature range of 230 – 260 °C and again an exothermal effect in the temperature range of 255 – 365 °C. The maximum overall energy release of the exothermal effects was 495 J/g.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The heat of decomposition in the DCS measurements was < 500 J/g. Therefore, and under the assumption that the test item consisted mainly of organic components the main test on explosive properties was not necessary.
