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:
- 12.10.2006-19.10.2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:

- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- yes
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -37 °C
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The test item had a freezing point of < -37 °C under atmospheric conditions.
- Executive summary:
A study was conducted according to OECD TG 102. The freezing point was determined by cooling the test item using appropriate sample tube. The temperature during crystallization was observed. The stirrer was inserted into the crystallisation tube filled with the test item. The thermometer was secured vertically in the liquid with its end appr. 18 mm above the bottom of the tube. The outer tube was fitted. Afterwards the whole was placed in position in a cooler enabling cooling to -40°C. The freezing point of the test item was determined to be below - 37 °C.
