During the heating phase the test item showed an endothermic signal in the temperature range of 110-200°C that can be associated with the boiling point of the test item. The lowest measured onset temperature is corrected to the standard pressure to be 166.93 °C and the highest onset temperature to be 167.72 °C.
As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 167.33 °C, the test item has a boiling point of 167.3 °C.
No further effects were observed up to 500 °C
