Applicant's summary and conclusion

Conclusions:
The test item shows no melting of crystalline subcomponents (in the 1st to 3rd heating run) up to 219°c (at 219°c probably the test item starts to decompose) according to the definition in the OECD Guideline 102 (mean value from repeat determinations).
