Conclusions:
The boiling temperature range of the test item has been determined to be: 286 - 291 °C at 1013.25 hPa.
Executive summary:

The boiling temperature was determined using EU Method A.2. and OECD TG 103 Differential Scanning Calorimetry method under GLP. After determination of the melting point the test item showed a second endothermic signal in the temperature range of 230 - 350 °C that can be associated with the boiling of the test item. The lowest measured onset temperature is corrected to the standard pressure to be 286.31 °C and the highest onset temperature to be 290.56 °C. As the corrected onset temperatures in both tests deviate by more than 0.5 K from their mean value of 288.44 °C, the test item has a boiling range from 286 °C to 291 °C. No further thermal effects were observed up to the test end temperature of 500 °C. The boiling temperature range of the test item was determined to be 286 to 291 °C at 1013.25 hPa.
