Results and discussion
Small-scale preliminary tests
- Parameter:
- other: Thermal sensitivity
- Remarks:
- 1.34 mg of the test substance was weighed in a stainless steel high pressure crucible and closed, crucible 619.7mg. The crucible was then placed into a muffle furnace and heated to 520°C.
- Value:
- 619.7
Results of test series for explosivesopen allclose all
- Test series:
- other: Small-scale preliminary tests 01
- Method:
- other: Thermal stability
- Parameter:
- other: visual observation, mass crucible 616.1 mg
- Value:
- 616.1
- Result:
- negative, no explosion
- Remarks on result:
- other: test substance was carbonised
- Key result
- Test series:
- other: DSC
- Method:
- other: OECD 113
- Parameter:
- limiting impact energy (J)
- Remarks:
- During the DSC run one event was observed. The event shows a sharp endotherm peak which went into a sharp exothermic peak. The energy was with -251.40 J/g below the threshold of -500 J/g.
- Value:
- -251.4
- Result:
- negative, no explosion
Applicant's summary and conclusion
- Interpretation of results:
- other: The energy was with -251.40 J/g below the threshold of -500 J/g. Therefore no further tests for explosive properties have to be performed.
- Conclusions:
- 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.
