Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Principles of method if other than guideline:
- The capillary method is used to determine the melting temperature. The substance is heated up to 405°C in a glass capillary tube within an aluminium block until melting can be observed. In additon, a second test system is established to achieve melting of substances with higher melting temperature. The substance is heated in a porcelain crucible in a muffle oven up to 1095°C according to an internal operation protocol of the testing laboratory (SOP 114 003 70, edition 1 dated 03. September 2009).
- GLP compliance:
- no
- Type of method:
- capillary method

Results and discussion
Melting / freezing point
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: charcoal showed no signs of melting under the test conditions described.
Applicant's summary and conclusion
- Conclusions:
- Since there were no signs of melting up to a temperature of >1000°C, no melting point of the test item could be determined.
