Thermal Stability
The DSC-measurement in a closed glass crucible with the test item showed an endothermic effect in the temperature range 195-230 °C directly followed by an exothermal decomposition in the temperature range 230 - 390 °C with an energy of 826 J/g.
Explosive Properties
The heat of decomposition was above 500 J/g. Therefore the main test on explosion properties was performed.
Mechanical Sensitivity (Friction):
No explosion was observed within 6 tests using a pinload with 360 N.
Mechanical Sensitivity (Shock):
No explosion within 6 tests using a mass of 10 kg falling from a height 0.4 m was observed.
Thermal sensitivity:
Three tests were performed with a circular nozzle plate with a hole of 2 mm diameter.
Test no. | Weight of test item (g)
| Nozzle width (mm)
| t1 (s) | t2 (s) | Reaction | Appearance; Number of Fragments |
1 | 17.0 | 2.0 | 28.5 | > 300.0 | Flame | 0 |
2 | 17.4 | 2.0 | 33.4 | > 300.0 | Flame | 0 |
3 | 17.2 | 2.0 | 27.5 | > 300.0 | Flame | 0 |
t1: time to any reaction, e.g. whistle or flame
t2: time to any reaction and duration of reaction, e.g. rupture of tube or flashing
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 (pure substance) 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 is excluded.
Final Results
The test item has no danger of explosion according to the explosive properties in the sense of the consolidated version of Council Directive 67/548/EEC Annex V, A.14.
Description of key information
non explosive
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
The test item is no explosive according to EU Test method A.14 (EU A.14; Thermal sensitivity, Mechanical Sensitivity (Shock and Friction))
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 chemical structure the substance is not explosive. Also the substance is non explosive according to EU Test method A.14.
