Any other information on results incl. tables

Two DSC-measurements in closed glass crucibles showed an endothermal effect in the temperature range of 115 – 150 °C and an exothermal effect in the temperature range of 225 – 480 °C with a maximum energy release of 499 J/g. The measurements were terminated at 500 °C.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.
Executive summary:

The purpose of the study was to determine the explosive properties of the test item according to European Commission Regulation (EC) No. 440/2008, Methods for the determination of physico-chemical properties (Part A): A.14. Explosive properties and OECD test guideline: OECD 113 Screening test for thermal stability and stability in air, and following GLP.

The sample was tested as received. No further preliminary treatment such as drying or milling was performed. The results given in this report only apply to the tested sample.

The heat of decomposition was below 500 J/g. Therefore the main test on explosive properties was not necessary. The test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.
