Two individual measurements were made, both yielding freezing points of -14.5 °C.

Conclusions:
The freezing point of the substance is -14.5 °C at standard atmospheric pressure.
Executive summary:

The freezing point of the test substance was determined in accordance with EU Method A.1. 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 (Amarell, serial number 8442, range -30 to +30 °C, fractional division 0.1 °C, uncertainty 0.03 °C). The freezing point is reached when the temperature remains constant. The freezing point was determined to be -14.5 °C under atmospheric pressure of 1013 hPa.

Description of key information

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-14.5 °C

Additional information

The freezing point of the test substance was determined in accordance with EU Method A.1 to be -14.5 °C. This value is supported by handbook data reporting a freezing point in the range of -12.4 to -15 °C.
