Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The PyOxim substance is incapable of sustaining detonation. The substance passed the UN Test Series 3 and 2. Therefore, due to these considerations, SCE concludes that there is no explosive hazard when shipping the substance presented for consideration in this report.
Executive summary:

Tests were performed per UN Manual of Tests and Criteria, Section 33, Classification Procedures, Test Methods and Criteria Relating to UN Test Series 3 and 2. The results of these tests for the substance was “negative”.



The PyOxim substance is incapable of sustaining detonation. The substance passed the UN Test Series 3 and 2. Therefore, due to these considerations, SCE concludes that there is no explosive hazard when shipping the substance presented for consideration in this report.
