Key result
Melting / freezing pt.:
< -20 °C
Atm. press.:
101.3 kPa

Two individual measurements were made, both yielding freezing points below -20 °C.

Conclusions:
The freezing point of the test substance is below -20 °C at standard atmospheric pressure.
Executive summary:

The freezing point of the test substance was determined in accordance with EU Method A1. Test substance was filled into a solidification tube with a diameter ranging from 18 to 25 mm. The substance was then cooled down and stirred slowly and continuously with a precision thermometer. The freezing point is reached when the temperature remains constant. The freezing point of the test substance was below -20 °C at standard atmospheric pressure.
