Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Principles of method if other than guideline:
- The drop point is the temperature at which the first drop of sample falls from the cup under the specified conditions of the test.The Drop Point Method is an alternative to melting point and is used when due to the complex nature of the substance melting occurs over a wide range of temperatures. This end point effectively shows when the material would start to flow – i.e. behave as a liquid rather than a solid. Drop points are measured routinely and averages over several batches are given for lanolin alcohols.
The apparatus is filled with the sample and the temperature is raised until the first drop of sample falls and is detected photoelectrically within the FP83HT measuring cell. - GLP compliance:
- no
- Type of method:
- other: Differential scanning calorimetry (DSC)
