- Type of method:
- capillary method
- Key result
- Melting / freezing pt.:
- > 400 °C
- Decomposition:
- no
- Remarks on result:
- other: No melting point was observed up to 400 °C.
- Conclusions:
- Under the conditions of this study, no melting point for the test material was observed up to 400 °C. No physical change of colour or form was observed, there was no visual indication of decomposition.
- Executive summary:
The melting point of the test material was investigated in accordance with the standardised guidelines OECD 102 and EU Method A.1, under GLP conditions using the capillary method.
For the main study three capillaries containing the test material were placed into the apparatus, the block was heated from 390 to 400 °C at 0.5 °C/min heating rate. The transformations of the test material were observed, visually through the magnifying glass. Three parallel experiments were carried out and in each case three parallel samples were measured.
Under the conditions of this study, no melting point for the test material was observed up to 400 °C. No physical change of colour or form was observed, there was no visual indication of decomposition.
Reference
- No melting point was observed up to 400 °C.
- No physical change of colour or form was observed, there was no visual indication of decomposition.
