The determination was carried out three times, whereby the individual results did not differ by more than 0.5 °C. The temperature of the sample was determined by the same method.

The arithmetic mean was given in °C and rounded to 0.5 °C as the final result.

Measured values of the test substance:

1. - 4.5 °C

2. - 4.5 °C

3. - 4.5 °C

Mean value: -4.5 °C

The freezing point of the test substance is - 4.5 °C.

Conclusions:
The freezing point of the test substance is - 4.5 °C.
Executive summary:

The freezing point was tested according to EU Method A.1 in a GLP study. The freezing point of the test substance is - 4.5 °C.

Description of key information

The freezing point was tested according to EU Method A.1 in a GLP study. The freezing point of the test substance is: - 4.5 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-4.5 °C

Additional information

No atm. pressure is mentioned in the report, but 1013 hPa as standard conditions can be assumed. This does not affect the CSA.
