Applicant's summary and conclusion

Conclusions:

The test item was determined to decompose from approximately 232 °C (505 K) prior to melting. As the test item decomposed, no value for melting temperature could be determined.

Executive summary:

The determination was carried out by differential scanning calorimetry using a procedure designed to be compatible with Method A1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Conclusion

The test item was determined to decompose from approximately 232 °C (505 K) prior to melting. As the test item decomposed, no value for melting temperature could be determined.
