Applicant's summary and conclusion

Conclusions:
According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation the determination of the melting-/freezing point does not need to be conducted below a lower limit of - 20 °C.
Therefore, no additional test was conducted for the test item and the freezing point is stated as: below - 20 °C (< 253.15 K).
