Thermal stability
Two DSC-measurement in closed glass crucible with the test item showed exothermal effects in temperature ranges of 240-430 °C and 235-415 °C, with enthalpies of -897 J/g and -763 J/g, respectively.
The heat of decomposition was above 500 J/g. Therefore the main test on explosive properties was performed.
Mechanical Sensitivity (Friction)
The test item was sieved (mesh size 0.5 mm) before the measurement. No explosion occurred within 6 tests using a pinload of 360 N, only a discoloration of the test item was observed.
Mechanical sensitivity (shock)
The test item was sieved (mesh size 0.5 mm) before the measurement. No explosion within 6 tests using a mass of 10 kg falling from a height of 0.4 m was observed, only a decomposition in the tests was observed.
Thermal sensitivity
Three tests were performed with a circular nozzle plate with a hole of 2 mm diameter. No explosion was observed. The results of the thermal sensitivity are reported in the following table.

The test on thermal sensitivity carried out with a nozzle with a diameter of 2.0 mm showed no explosion. Compared to the nozzle with a diameter of 6.0 mm the venting area of the nozzle with 2.0 mm is smaller by an order of magnitude. Additionally the physical state of the test item excludes the enrichment of high-energy components caused by evaporation of volatile solvents. Due to these facts an explosion with a nozzle width of 6.0 mm was excluded.
Final results
The test item, pure substance had no explosive properties in the sense of the EU Method A. 14.
Thermal stability
Two DSC-measurement in closed glass crucible with the test item showed exothermal effects in temperature ranges of 235-415 °C and 235-420 °C, with enthalpies of -770 J/g and -810 J/g, respectively.
The heat of decomposition was above 500 J/g. Therefore the main test on explosive properties was performed.
Mechanical Sensitivity (Friction)
The test item was sieved < 0.5 mm. No explosion occurred within 6 tests using a pinload of 360 N, only a discoloration of the test item was observed.
Mechanical sensitivity (shock)
The test item was sieved < 0.5 mm. No explosion occurred within 6 tests using a mass of 10 kg falling from a height of 0.4 m, only a discoloration in the tests was observed.

Additional information
Justification for classification or non-classification
The available data on explosive properties 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: Based on thermal, friction and shock sensitivity tests the substance is not explosive.
