DSC

A DSC-measurement in a closed crucible with the test item showed an endothermal effect in the temperature range of 180 – 225 °C and an exothermal effect in the temperature range of 225 –380 °C with an energy release of 2175 J/g. Due to the fact that the heat production was finished the measurement was terminated at 400 °C. After the measurement the test item was black.

Mechanical sensitivity (friction):

Due to the particle size of the test item (L50 = 6 μm) grinding and sieving was not necessary. No explosion occurred within 6 tests using a pinload of 360 N, only a discoloration of the test item was

observed in all tests.

Mechanical sensitivity (shock):

Due to the particle size of the test item (L50 = 6 μm) grinding and sieving was not necessary. 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 with a hole of 2 mm diameter. No explosion was observed.

Applicant's summary and conclusion

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