- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Version / remarks:
- 1998
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 1 (Freezing Point)
- Version / remarks:
- 2009
- Deviations:
- no
- GLP compliance:
- no
- Remarks:
- Study was not performed under GLP, however the test facility was GLP-compliant.
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- < -100 °C
- Atm. press.:
- 1 021 hPa
- Remarks on result:
- other: No melting point down to -100°C
- Conclusions:
- The test item has no melting point down to -100°C at atmospheric pressure (1021 hPa), as determined by differential scanning calorimetry.
- Executive summary:
Melting point was determined by differential scanning calorimetry according to OECD Guideline 102 and EU Method A.1 (2017). The study was not performed under GLP, however the test facility was GLP-compliant. The study is considered to be reliable without restrictions (Klimisch 1). The test item has no melting point down to -100°C at atmospheric pressure (1021 hPa).
Reference
No thermal effects were observed in the temperature range from -100 to 25°C. It can be assumed that the test item has no melting or freezing point in this temperature range. Therefore the test item has no melting point down to a temperature of -100°C.
Description of key information
The test item has no melting point down to -100°C at atmospheric pressure.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -100 °C
Additional information
Melting point was determined by differential scanning calorimetry according to OECD Guideline 102 and EU Method A.1 (2017). The study was not performed under GLP, however the test facility was GLP-compliant. The study is considered to be reliable without restrictions (Klimisch 1). The test item has no melting point down to -100°C at atmospheric pressure.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
