Reference
The test item was tested as received. No further preliminary treatment such as drying or milling was performed.
Thermal stability
The DSC-measurements in closed glass crucibles with the test item showed an exothermal effect in the temperature range of 225 – 325 °C with an median enthalpy of -1320 J/g. The results are summarized in Table 1.

Explosive properties
The heat of decomposition was above 500 J/g. Therefore the main test on explosive properties had to be performed.
Mechanical sensitivity (friction):
No explosion occurred within 6 tests using a pinload of 360 N. Only a discolouration was observed in all six tests.
Mechanical sensitivity (shock):
No explosion within 6 tests using a mass of 10 kg falling from a height of 0.4 m was observed. Only decomposition was observed in all six tests.
Thermal sensitivity:
Three tests were performed with a circular nozzle plate with a hole of 2 mm diameter. Table 2 gives the results of the thermal stability.

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.
Description of key information
The explosiveness of the test item was determined according to the European Commission Regulations (EC) No. 440/2008,
A.14. Explosive properties and according to and OECD test guideline, OECD 113 Screening test for thermal stability and stability in air.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
The test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.
