Thermal stability (DSC)
The test item shows a weak endothermic effect in the temperature range of 100 – 120 °C. An exothermic effect is observed in the temperature range from 150 – 200 °C with a maximum energy release of -20 J/g followed by an endothermic effect in the temperature range of 230 – 260 °C.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In the DSC-measurements the test item Leuco Sulphur Brown 46 showed an exothermic effect from 150 °C with a maximum energy release of -20 J/g. Due to the fact that the energy of the exothermic decomposition was below the threshold of
-500 J/g, further tests on explosive properties had not to be performed.
According to the results of the test on thermal stability, the test item is classified as follows:
UN Transport Regulation: The test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation.
GHS (CLP Regulation EC 1272/2008: Annex 1: 2.1): The test item does not have to be classified as explosive substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.1, respectively.
Regulation EC 440/2008 and Directive 67/548/EEC: The test item has no explosive properties according to the Regulation EC No. 440/2008 Method A.14. Explosive Properties. - Executive summary:
