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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Batch 3033900250
- Key result
- Melting / freezing pt.:
- > 500 °C
- Decomposition:
- yes
- Decomp. temp.:
- 222 °C
- Conclusions:
- The melting temperature was investigated according to EU Method A.1. and OECD 102. A sample was charged to a Tzero aluminium DSC crucible which was then sealed and placed in the furnace.
On completion of the screening test, aluminium crucible has been opened and sample appearance observed as grey powder. Endothermic event was observed with onset temperature of 222.2°C, however no signs of formed droplets found in crucible after the test. Sample did not melt up to 500°C. Test terminated. Therefore, boiling point is exempt. - Executive summary:
