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:
- Testing was conducted between 02 October 2009 and 24 December 2009.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Date of GLP inspection: 2009-09-15 Date of Signature on GLP certificate: 2009-11-26
- Type of method:
- other: Differential scanning calorimetry (DSC)
- Melting / freezing pt.:
- > 723 K
- Conclusions:
- The test material was determined to have a melting temperature of greater than 723 K.
This study is conducted according to an appropriate guideline and under the conditions of GLP and therefore the study is considered to be acceptable and to adequately satisfy both the guideline requirement and the regulatory requirement as a key study for this endpoint. - Executive summary:
INTRODUCTION
The physico-chemical properties of the test material have been determined.
Methods employed complied with those specified in Commission Regulation (EC) No 440/2008 of 30 May 2008, Part A: Methods for the determination of physico-chemical properties and Part C: Methods for the determination of ecotoxicity.
Testing was conducted between 02 October 2009 and 24 December 2009.
Method
The determination was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86, Method A1 Melting/Freezing Temperature ofCommissionRegulation (EC) No 440/2008 of 30 May 2008.
Overall result:
No definitive signs of melting.
Conclusion
The test material was determined to have a melting temperature of greater than 723 K.

Description of key information
One key study exists. This study was performed in accordance with EU Method A1 and under the conditions of GLP. This study is considered to be appropriate and reliable for use as a key study in accordance with Regulation (EC) No. 121907/2006 (REACH). No further testing is required.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 450 °C
Additional information
The test material was determined to have a melting temperature greater than 723 K / 450°C
