Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
other: OECD 113 (Thermal stability)
Principles of method if other than guideline:

GLP compliance:
yes (incl. QA statement)
Parameter:
other: decomposition energy is below 500 J/g
Remarks on result:
negative (not further specified)

The first DSC measurement in closed glass crucibles showed an endothermal effect in the temperature range of 210 - 440 °C. No further endothermal or exothermal effects were observed up to the final temperature (500 °C).

The second DSC measurement in closed glass crucibles showed an endothermal effect in the temperature range of 370 - 495 °C. No further endothermal or exothermal effects were observed up to the final temperature (500 °C).

Interpretation of results:
GHS criteria not met
Conclusions:
The test item had no explosive properties under the test conditions.
Executive summary:

As a screening method for the determination of explosive properties a differential scanning calorimetry (DSC) under nitrogen was performed according to OECD guideline 113.

The test item and the standard material (aluminium oxide) were heated up from ambient to the final temperature (500 °C) at a constant heating rate (3 K/min) in a defined atmosphere (nitrogen). Closed glass crucibles in high pressure crucibles were used as containers for the test item and the standard material. The quantity of heat absorbed or released was measured and recorded.

As the decomposition energy is below 500 J/g a main test for explosive properties is unnecessary (Recommendations on the Transport of Dangerous Goods I Manual of Tests and Criteria (ST/SG/AC.10/11/Rev.6)).
