Results and discussion

Small-scale preliminary tests
Key result
Parameter:
other: endothermal and exothermal events energy (J/g)
Remarks on result:
other: During the DSC run no exothermal event which should have been integrated to derive the related energy (in J/g) was observed
Remarks:
the test item is no subject to the classification procedures for self-reactive sub- stances and the acceptance procedures for Class 1 explosives need not to be applied

Any other information on results incl. tables

A screening test via DSC (differential scanning calorimetry) was conducted from 0 °C to 520 °C.

 

During the DSC run no exothermal event which should have been integrated to derive the related energy (in J/g) was observed. Only two endothermal events with slight turbulent baseline beginning at 274.34 °C were observed.

Therefore, the test item is no subject to the classification procedures for self-reactive sub- stances and the acceptance procedures for Class 1 explosives need not to be applied 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.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Therefore, the test item is no subject to the classification procedures for self-reactive sub- stances and the acceptance procedures for Class 1 explosives need not to be applied 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. This is extrapolated to CLP/GHS classification.
Executive summary:

In an OECD 113 themal stability test, the test item is no subject to the classification procedures for self-reactive sub- stances and the acceptance procedures for Class 1 explosives need not to be applied 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. This is extrapolated to CLP/GHS classification.
