Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- < -20 °C
- Remarks on result:
- other: Pour point
Any other information on results incl. tables
As a pour point of less than -20 °C was obtained in the preliminary test, the requirement of a main test to determine a definitive value was not necessary.
Applicant's summary and conclusion
- Conclusions:
- The pour point of the test item has been determined to be less than -20 °C (<253 K).
