During the heating phase the test item showed an endothermic signal in the temperature range of approx. 100 - 180°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 135.16 °C and the highest onset temperature to be 135.39 °C. As the corrected onset temperatures in both tests deviate by less than 0.5 K from their mean value of 135.28 °C, the test item has a boiling point of 135.3 °C. No further thermal effects were observed up to the maximum test temperature of 500°C.
