Thermal stability

Two DSC-measurements in closed glass crucibles with the test item showed an endothermal effect in the temperature range of 55 - 80 °C and an exothermal effect in the temperature range of 370 - 500 °C wíth a maximum energy release of 330 J/g.

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 has 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 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. Therefore the main test on explosive properties was not necessary and it was concluded that test item had no explosive properties.

Description of key information

The substance has no explosive properties.

Explosiveness:
non explosive

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 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. Therefore the main test on explosive properties was not necessary and it was concluded that test item had no explosive properties.

Justification for classification or non-classification

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

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