Conclusions:
The test item is a solid at 1013 hPa and 20 °C.
Executive summary:

Method

The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the ASTM E 794 -95.

Results

The value of the melting temperature corresponding to the fusion of the test substance, obtained from the average of the values returned from each test, resulted equal to 267.82 °C.

Conclusion

The test item is a solid at 1013 hPa and 20 °C.
