Applicant's summary and conclusion

Conclusions:
The test item has no boiling point at atmospheric pressure up to its decomposition starting at ca. 250°C.
Executive summary:

The boiling point of the test item was investigated in a study conducted according to OECD Guideline 103 (Boiling Point; 1995) and EU Method A.2 (Boiling Temperature; 2008) using DSC measurements. The DSC measurements indicated an exothermic effect between 250 and 500°C, with a max. decomposition energy of -660 J/g. Based on these results, it was concluded that the test item has no boiling point at atmospheric pressure up to the decomposition temperature of ca. 250°C.
