Applicant's summary and conclusion

Conclusions:
A screening test via DSC (differential scanning calorimetry) was conducted from
0°C to 520 °C.
During the DSC run two small exothermal events were observed at an onset of 382.70°C
and 383.91°C and this was integrated to derive the related energy (in J/g). The related energy of the observed exothermal event was -0.55 J/g and -4.54 J/g.
Based on the exothermal events, it is stated:
- As the released energy is less than 300 J/g, the test item is no subject to the classification procedures for self-reactive substances. (TDG/MTC*, 6th edition, 2015, §20.2.1).
- And as the released energy is less than 500 J/g, the acceptance procedures for Class 1 explosives need not to be applied. (TDG/MTC*, 6th edition, 2015, Appendix VI §3.3.c).
according to the “UN Recommendations on the Transport of Dangerous Goods; Manual of
Tests and Criteria”; sixth revised edition, 2015, Section 20.2.1, 20.3.3.3 and Appendix 6,
section 3.3.c.
The measurement of indium after calibration met the validity criteria. Therefore, the result
of the study is considered valid.
