- Type of method:
- method to determine freezing temperature
- Melting / freezing pt.:
- < -50 °C
- Atm. press.:
- 1 atm
- Remarks on result:
- other: < -50 °C or < 223 K
- Conclusions:
- The freezing temperature of the test item has been determined to be less than 223 K (or < -50 °C).
- Executive summary:
The melting/freezing temperature was determined using OECD TG 102 and EU Method A. 1 - crystallisation point / freezing temperature method under GLP. The mean freezing temperature of the test item has been determined to be less than 223 K or less than -50 °C at 1 atmosphere pressure.
