Applicant's summary and conclusion

Conclusions:
Reaction and/or decomposition of ASA404 C7 was observed during or directly after melting. Boiling of the test substance was not observed below
the temperature at which reaction and/or decomposition started. Therefore, the test substance has no boiling temperature. The melting temperature of the test substance (no part of the scope of the study) was: 242°C (515K).
