Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Principles of method if other than guideline:
- The Freezing temperature was determined according to “Differential scanning calorimetry (DSC)” in OECD Guidelines for the Testing of chemicals 102 - “Melting Point / Melting Range”. The sample and the reference material are subjected to the same controlled temperature programme. The difference in energy input necessary to maintain identical temperatures between the sample and the reference material is recorded. When the sample undergoes a phase transition, the corresponding change of enthalpy gives a departure form the base line of the heat flow record.
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
