A DSC-measurement in a closed glass crucible with the test item showed
an endothermal effect in
the temperature range of 100 - 155 °C. An exothermal effect was observed
in the temperature range of
175 - 260 °C with an energy of 583 J/g.
The heat of decomposition was above 500 J/g. Therefore the main test on
explosive properties had
to be performed.
A study was performed according to EU method A.14 to investigate
possible explosive properties of the test item. Different tests were
performed to identify the thermal stability and the explosive properties
due to friction, shock and thermal sensitivity.
As a screening method for the determination of explosive properties a
differential scanning calorimetry (DSC) under nitrogen was performed
which resulted in an exothermal effect in the temperature range of 175
-260 °C with an energy of 583 J/g. The heat of decomposition was above
500 J/g and therefore the main test was performed.
Mechanical sensitivity (friction):
No explosion occurred within 6 tests using a pin load of 360 N, only a
discoloration of the test item was observed.
Mechanical Sensitivity (shock):
No explosion within 6 tests using a mass of 10 kg falling from a height
0.4 m 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 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.
The test item has no explosive properties in the sense of the European
Commission Regulation (EC) No. 440/2008, Method A.14.
Based on the available information, no
classification for explosive properties has been warranted under CLP
Regulation (EC n. 1272/2008).
