no

No evidence of solidification or freezing of the test material was observed down to a temperature of 252 +/- 0.5K

Conclusions:
The freezing temperature has been determined to be less than 252 +/- 0.5 K.
Executive summary:

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.
