Applicant's summary and conclusion

Conclusions:

The test item has been determined to decompose from approximately 365 °C (638 K) at 99.7 kPa.

Executive summary:

The determination was carried out by differential scanning calorimetry, using a procedure designed to be compatible with Method A2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Discussion

As a result of the low rate of enthalpy change during decomposition, the onset temperature can only be approximated.

Conclusion

The test item has been determined to decompose from approximately 365 °C (638 K) at 99.7 kPa.
