Administrative data
Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Deviations:
- no
- GLP compliance:
- yes
- Parameter:
- thermal sensitivity - Koenen test: limiting diameter (mm)
- Remarks on result:
- not thermal sensitive if heated under defined confinement
- Parameter:
- sensitiveness to impact: impact energy (J)
- Remarks on result:
- not sensitive to impact using an impact energy of 40 J
- Parameter:
- sensitiveness to friction: friction load (N)
- Remarks on result:
- not sensitive to friction using a friction load of 360 N
- Endpoint:
- explosive properties of explosives
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance contains chemical groups associated with explosive properties which include oxygen, but the calculated oxygen balance is less than - 200

Screening test DSC
The measurement shows an endothermic effect (melting, 84.5 °C) and a decomposition of the test substance in the range 290-440 °C, with a decomposition energy of 610 J/g. So the test for explosive properties has to be performed.
Three tests were performed with a circular nozzle plate with a hole of 2 mm diameter used.

Mechanical sensitivity (shock)
No reaction within 6 tests using a 10 kilogram mass from a height 0.4 m was observed.
Mechanical sensitivity (friction)
No reaction within 6 tests pinload with 360 newton was observed.
Final result
The heat of decomposition was determined to be above 500 J/g. Therefore the test on explosion properties was performed.
The test substance has no danger of explosion according to the explosive properties in the
sense of Guideline 92/69/EEC, A.14.

Additional information
EU Method A.14; Thermal sensitivity, Mechanical Sensitivity (Shock and Friction)
There are chemical groups associated with explosive properties. A screening test shows an endothermic effect (melting, 84.5 °C) and a decomposition of the substance in the range 290 - 440 °C with decomposition energy of 600 J/g. But the calculated oxygen balance is less than -200.
Furthermore no mechanical sensitivity (shock and friction) was observed.
Justification for classification or non-classification
The available data on explosivity of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification: There are chemical groups associated with explosive properties, but based on the calculated oxygen balance (less than -200) the substance is considered to be not explosive.
