Results and discussion

Melting / freezing point
Melting / freezing pt.:
> 400 °C

Any other information on results incl. tables

The absence of any significant thermal events and the unchanged physical state/appearance of the test material residue on completion of each determination confirmed that no phase transition occurred. Therefore the melting temperature of the test material was greater than 400°C, >673 K.

Applicant's summary and conclusion

Conclusions:
The melting/freezing temperature of the test material has been determined to be greater than 673 K.
Executive summary:

Melting/Freezing Temperature:

Greater than 673 K, by differential scanning caloritry, using ASTM E537-86, Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.
