Applicant's summary and conclusion
- Conclusions:
- The freezing temperature of the test material was determined to be 270 ± 0.5 K. However, it only partially solidified to a "slush-like" consistency.
- Executive summary:
The freezing temperature of the test material was investigated and the determination was carried out in accordance with the standardised guidelines EU Method A.1 and BS4633: Method for the Determination of Crystallizing Point.
The freezing temperature of the test material was determined to be 270 ± 0.5 K. However, it only partially solidified to a "slush-like" consistency.
