- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 8 °C
- Atm. press.:
- 1 013.3 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The mean melting temperature of the test item is 8 °C.
- Executive summary:
The melting point of the test item was determined according to OECD test guideline 102 and Council Directive 92/69/EEC, Method A.1. Four DSC-runs in aluminium crucibles with a hole showed an endothermic effect in the temperature range of 2 - 30°C with an onset temperature of about 7 - 8 °C. The onset temperature is derived from the intersection of the tangent line with the highest slope of the endothermic peak with the baseline. Accordingly, the mean melting temperature of the test item was determined to be 8 °C.
