Method
The melting/freezing temperature was determined using method BS4633: Method for the Determination of Crystallizing Point, Method A1 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
Results
The freezing temperature has been determined to be less than 252 +/- 0.5 K.
Reference
No evidence of solidification or freezing of the test material was observed down to a temperature of 252 +/- 0.5K
Description of key information
The freezing temperature has been determined to be less than 252 ± 0.5 K (EU Method A.1).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 252 °C
