Applicant's summary and conclusion

Conclusions:
In the preliminary capillary test accoring to OECD guideline 102 and EC method A.1. no melting point could be observed as the test item started to decompose at a temperature of 215 °C. The test item began to change its color from grey to black at about 215 °C.
