Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 22 June 2003 to 3 July 2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM Test Method D97-87
- Deviations:
- no
- Principles of method if other than guideline:
- Substance solidified without crystallisation at approximately -4.5°C and so pour point test was implemented instead of freezing point
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pour point
- Key result
- Melting / freezing pt.:
- 0 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: Pour point
- Conclusions:
- The lowest temperature at which the test substance was still observed to flow was 0 °C.
- Executive summary:
The registered substance solidified without crystallisation at a temperature of -4.5 °C and so a pour point test was conducted instead according to ASTM Test Method D97 -87. The pour point is defined as the lowest temperature at which the substance will still flow. The pour point of the resgistered substance was identified as 0 °C.

Description of key information
The study was performed on the registered substance. The pour point was reported as 0 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 0 °C
Additional information
The study was performed on the registered substance. A preliminary freezing temperature study indicated that the substance was solidifying around -4.5 °C. As a result, it was decided to perform an evaluation of the pour point according to ASTM Test Method D97-87. The pour point of the registered substance was determined to be 0 °C.
