Thermal stability: Two DSC-measurements in closed glass crucibles with the test item showed an endothermal effect in the temperature range of 65-110°C and an exothermal effect in the temperature range of 335-485°C with a maximum energy of 690 J/g.

Explosive properties: The heat of decomposition was above 500 J/g. Therefore the main test on explosive properties had to be performed.

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.

Thermal sensitivity: Three tests were performed with a circular nozzle plate wit a hole of 2 mm diameter. No explosion was observed.

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 6.0 mm the venting area of the nozzle with 2.0 mm is smaller by an order of magnitude. Additionally the physcal state of the test item excludes the enrichment of high energy components caused by evaporation of volatile solvents. Due to these facts an explosin with a nozzle width of 6.0 mm was excluded.

Conclusions:
The test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.
