- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:

- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -29 °C
- Conclusions:
- The freezing point of the test item was determined to be below - 29 °C.
- Executive summary:
An experimental study was conducted according to Regulation (EC) No 440/2008 Methods A.1. and OECD Test Guidelines 102 to determine the freezing point of the test item. In a preliminary test the test item did not freeze when stored at - 29 °C. Therefore, the main study was not performed as the freezing point of the test item is below - 29°C.
