- 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.
Reference
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.
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.
