Applicant's summary and conclusion

Conclusions:
The test material has been determined to decompose from approximately 516 K at 102.8 kPa.
Executive summary:

Decomposed from approximately 516 K at 102.8 kPa. As the test material decomposed, no value for the melting temperature could be determined, by differential scanning calorimetry, using ASTM E537-86, Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008.
