Key result

Parameter:

other: Heat of decomposition

Remarks on result:

negative (not further specified)

Remarks:

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 in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.

Thermal stability

A DSC-measurement with the test item in a closed glass crucible, which was placed in a closed high-pressure crucible, showed no thermal effect in the temperature range of 25 – 500 °C. In accordance, a second DSC-measurement with the test item in a closed glass crucible showed no thermal effect in the temperature range of 25 – 500°C.

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 in the sense of the UN Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria, Appendix 6: Screening Procedures and in the sense of the EuropeanCommission Regulation (EC) No. 440/2008, Method A.14.

Executive summary:

Study performed in accordance with EU Method A.14 (Explosive properties)

 

Thermal stability

As a screening method for the determination of explosive properties a differential scanning calorimetry (DSC) under nitrogen was performed.

If the decomposition energy is below 500 J/g and the onset of exothermal decomposition is below 500 °C a main test for explosive properties is unnecessary (Recommendations on the Transport of Dangerous Goods / Manual of Tests and Criteria (ST/SG/AC.10/11, Rev.5, 2009, p. 440). This is only valid for organic substances and homogeneous mixtures of organic substances.

The test item and the reference are 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.

 

Results

A DSC-measurement with the test item in a closed glass crucible, which was placed in a closed high-pressure crucible, showed no thermal effect in the temperature range of 25 – 500 °C. In accordance, a second DSC-measurement with the test item in a closed glass crucible showed no thermal effect in the temperature range of 25 – 500°C.

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 in the sense of the UN Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria, Appendix 6: Screening Procedures and in the sense of the EuropeanCommission Regulation (EC) No. 440/2008, Method A.14.

Additional information

As a screening method for the determination of explosive properties a differential scanning calorimetry (DSC) under nitrogen was performed.

A DSC-measurement with the test item in a closed glass crucible, which was placed in a closed high-pressure crucible, showed no thermal effect in the temperature range of 25 – 500 °C. A second DSC-measurement with the test item in a closed glass crucible showed no thermal effect in the temperature range of 25 – 500°C.

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.

Justification for classification or non-classification

The test substance is not classified as explosive in accordance with the CLP Regulation.
