- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -25 °C
- Remarks on result:
- not determinable
- Conclusions:
- The freezing temperature of the test material was determined to be less than -25 °C.
- Executive summary:
The freezing point of the test material was determined in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions using a suitable apparatus (Seta Freezing Point Apparatus, Stanhope Seta Ltd.).
Under the conditions of this study, the freezing temperature of the test material was determined to be less than -25 °C.
Reference
In a trial determination, the test material did not solidify as the temperature was decreased from ambient temperature down to -25 °C. No further testing was necessary, as the test material was still liquid at -25 °C.
Description of key information
Under the conditions of this study, the freezing temperature of the test material was determined to be less than -25 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -25 °C
Additional information
The freezing point of the test material was determined in accordance with the standardised guidelines OECD 102 and EU Method A.1 under GLP conditions using a suitable apparatus (Seta Freezing Point Apparatus, Stanhope Seta Ltd.). The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Under the conditions of this study, the freezing temperature of the test material was determined to be less than -25 °C.
