Applicant's summary and conclusion

Conclusions:
The test item started to melt at 216°C (ca. 1013 hPa) under decomposition.
Executive summary:

The melting point of the test item was investigated using DSC. In the DSC run, the onset temperature (melting point/decomposition) was determined to be 216°C at ca. 1013 hPa (no further thermic effects were observed up to this temperature).
