Calibration
After calibration with indium and zinc the measurement of indium yielded the following values:

Assessment |
156.6 ± 1.0°C |
156.38 °C (onset) |

The measurement of indium after calibration met the validity criteria.
DSC Screening of the Test substance
1sttest: No exothermic event was detected until 500°C.
2ndtest: No exothermic event was detected until 500°C. Only a small endothermic event at 287.58 °C and a sharp increasing baseline at 511.52 with a peak maximum of 513.30 °C were detected.
3rdtest: No exothermic event was detected until 500°C.
4thtest: No exothermic event was detected until 500°C. Only a small endothermic event at 403.23 °C was detected.

Final Results
A screening testvia DSC (differential scanning calorimetry) was conducted from 0°C to 520 °C. During the DSC run no exothermic event was observed.
Therefore, the test substance is no subject to the classification procedures for self-reactive substances and the acceptance procedures for Class 1 explosives need not to be applied
according to the “UNRecommendations 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.
Overall conclusion
Referring to the DSC (differential scanning calorimetry) measurements the test substance Lanthancarbonate is not subject to the classification procedures for self-reactive substances and the acceptance procedures for Class 1 explosives need not to be applied
according to the “UNRecommendations 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.
