Applicant's summary and conclusion
- Conclusions:
- The test item had no melting point up to 400 °C.
- Executive summary:
The DSC-measurement of the test item in an aluminium crucible with a hole showed an endothermal effect in the temperature range 130- 155 °C which was directly followed by an exothermal effect. The DSC measurements in glass crucibles (closed and open) showed an endothermal effect but no exothermal effect over their whole measurement range. Additionally after the measurement in an open glass crucible the test item was unchanged. Therefore it can be concluded that the exothermal effect in the aluminium crucible with a hole was either caused by an ambiguous baseline (leading to difficulties in the interpretation) or by a reaction of the test item with the material of the crucible. Due to this behaviour in the aluminium crucible with a hole this measurement will not be taken into consideration for the final result. The capillary method measurements showed that the test item started to form liquid at 155 °C. This can be explained by residual moisture or water of crystallization step. Therefore it can be assumed that the endothermal effect in the DSC-measurement (open glass crucible) in the temperature range 70 - 180 °C and the formation of condensing liquid in the capillary measurement was caused by the residual moisture/water of crystallization. However the forming liquid did not seem to evaparate as there was no mass loss observed in the DSC-measurement (open glass crucible). Due to the aforementioned reasons it can be concluded that the test item had no melting point up to 400 °C (final measurement temperature).
