Reference
The DSC-measurement in a closed glass crucible with the test item showed multiple endothermic effects in the temperature ranges of 60 – 105 °C, 105 – 140 °C, 155 – 210 °C and 220 – 340 °C, respectively. No further endothermic or exothermal effects were observed up to 500 °C.
Due to the inorganic nature of the test item, the main test had to be carried out.
Mechanical sensitivity (friction): No explosion occurred within 6 tests using a pinload of 360 N 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.
Thermal sensitivity: Three tests were performed with a circular nozzle plate with a hole of 2 mm diameter.

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 is excluded.
Description of key information
non explosive (EU A.14)
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
The explosivity of the test item was determined according to EC Method A.14.
Justification for classification or non-classification
The available data on explosivity 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: The substance is not an explosive according to the criteria of
EC Method A.14.
