Results and discussion

Applicant's summary and conclusion

Conclusions:
From the obtained experimental data according to the Manual of Tests and Criteria
ST/SG/AC.10/11/Rev. 5 – Part III, Appendix 6, Section 3, it can be concluded that the total
heat of decomposition is < 500 J.g-1 and therefore the test items ample is not a candidate for
classification as a UN Class 1 explosive substance.
