- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 method A.14. to determine the explosive properties of the test item. A screening test on thermal stability using differential scanning calorimetry (DSC) under nitrogen was performed. The test item and the reference were heated up from ambient to the final temperature at a constant heating rate (3 K/min) in a defined atmosphere (nitrogen). Closed crucibles were used as containers for the test item and the reference. The quantity of heat absorbed or released was measured and recorded. The heat of decomposition was below 500 J/g (maximum overall energy release of 571 J/g). Therefore, the main test on explosive properties had to be performed. With regard to the mechanical sensitivity, no explosion was observed within 6 tests using a mass of 10 kg falling from a height of 0.4 m. In order to determine the thermal sensitivity, 3 tests each were carried out with a circular nozzle plate with a hole diameter of 2 and 6 mm. No explosion was observed. Thus, the test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.
Reference
Thermal stability
One DSC measurement in a closed glass crucibles showed an exothermal effect in the temperature range of 185 - 385 °C with an energy release of 571 J/g. A second DSC measurement in a closed gold crucible with the test item showed exothermal effects in the temperature range of 210 - 330 °C and in the temperature range of 335 - 400 °C. According to the specifications of the crucibles the measurement was determined at 400 °C. Due to the course of the base line it cannot be excluded that the exothermal effect would have continued above 400 °C. The measurement showed an energy release of > 309 J/g.
Table 1: Thermalstability (DSC measurements)
Ident-No. | Weight / mg | Final temperature / °C | Temperature range / °C | Type of effect | Energy / J/g |
38831 | 10.34 | 500 | 185 – 385 | Exothermal | 571 |
38846 | 6.93 | 400 | 210 – 330 335 - 400 | Exothermal Exothermal | 50 > 259 |
With the DSC measurements it could not be excluded that the heat of decomposition was below 500 J/g. Therefore the main test on explosive properties had to be performed.
Mechanical sensitivity (shock)
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 and three tests were performed with a circular nozzle plate with a hole of 6 mm diameter. No explosion was observed.

Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on the structure of the molecule and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the seventeenth time in Regulation (EU) 2021/849, the test item does not have to be classified with respect to explosiveness.
