- Version / remarks:
- 1995
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- no
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -50 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:

- Conclusions:
- The Freezing point of test item was determined according to OECD guideline No. 102 (method of the freezing temperature), EU Method A.1 (Melting / Freezing Temperature) and EPA OPPTS 830.7200 (Melting Point / Melting Range). The Freezing point of test item was determined to be < - 50.0°C (223.15 K).
- Executive summary:
The Freezing point of test item was determined according to OECD guideline No. 102 (method of the freezing temperature), EU Method A.1 (Melting / Freezing Temperature) and EPA OPPTS 830.7200 (Melting Point / Melting Range). The thermometer was checked against a certified thermometer. In a preliminary test, no congealing was observed down to a temperature of -50.0 °C. Since no congealing was observed in preliminary test, no further test was undertaken.
The Freezing point of test item was determined to be < - 50.0°C (223.15 K).
Reference
The thermometer was checked against a certified thermometer
In a preliminary test, no congealing was observed down to a temperature of -50.0 °C. Since no congealing was observed in preliminary test, no further test was undertaken.
Description of key information
The freezing point of test item was stated as below 223.15 K (-50°C°). Test item is liquid at ambient temperature.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 223.15 K
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC method is available. It is considered as a key study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
