- Conclusions:
- Bayscript Gelbkomponente has a melting point of 147.3 °C determined via Differential Scanning Calorimetry according to OECD guideline No. 102.
- Executive summary:
The test was performed as stipulated in EC Test Procedure A.1 'Melting/Freezing Temperature' - ASTM E 537 'Standard method for assessing the thermal stability of chemicals by methods of differential thermal analysis'.
The Differential Scanning Calorimetry (DSC) was used. This technique records the difference of the temperature of a substance and a crucible with an inert sample. The substance and reference crucible were subjected to the same controlled temperature program. The sample was heated in a glass crucible at a linear rate of 1 K/min from 120 °C up to 180 °C. The measurement was recorded electronically.
Results to Bayscript Gelbkomponente:
No. Sample mass [mg] Melting point [°C] 1 15.9 147.3 2 13.0 147.1 3 13.1 147.4 Mean value 147.3 Bayscript Gelbkomponente has a melting point of 147.3 °C determined via Differential Scanning Calorimetry according to OECD guideline No. 102.
