After the test the crucible was visually unchanged. The crucible was opened, a black residue was observed, the inside sealed gold ring was black discoloured.

Finally, during the DSC run (from 0 to 520 °C) no significant exothermic event was observed.

The measurement of indium after calibration met the validity criteria. Therefore, the result of the study is considered valid.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
A screening via DSC (differential scanning calorimetry) was conducted.
During the DSC run (from 0 to 520 °C) no significant exothermic event was observed. The acceptance procedures for Class 1 explosives need not to be applied.
No additional testing is required. The substance shall not be classified as explosive according to Regulation (EC) N°1272/2008 (CLP).

Executive summary:

The thermal stability of the test substance was tested with Differential Scanning Calorimetry, in accordance with conditions recommended in UN MTC screening procedure/OECD guideline. Up to the maximum test temperature of 520°C, no significant exothermic event was observed.
