Thermal stability

Two DSC measurements in closed glass crucibles with the test item showed an endothermal effect in the temperature range of 65 - 90 °C and two exothermal effects in the temperature range of 160 -210 °C and 460 - 490 °C with a maximum overall energy release of 131 J/g.

Explosive properties

The heat of decomposition was below 500 J/g. Therefore the main test on explosive properties was not necessary.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item had no explosive properties.
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 are used as containers for the test item and the reference. The quantity of heat absorbed or released is measured and recorded. The heat of decomposition was below 500 J/g. Therefore the main test on explosive properties was not necessary. The test item had no explosive properties.

Additional information

A study was conducted according to Regulation (EC) No 440/2008 method A.14 to determine the explosive properties of the test item (reference 4.14 -1). 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 are used as containers for the test item and the reference. The quantity of heat absorbed or released is measured and recorded. The heat of decomposition was below 500 J/g. Therefore the main test on explosive properties was not necessary.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008

Based on experimental results and taking into account the provisions laid down in Regulation (EC) No 1272/2008,as amended for the twelfth time in Regulation (EU) No 2019/521, the substance is not considered to be classified for explosive properties.
