Results
An endothermic effect (melting) was observed in the temperature range of
-40 to -30 °C.

The endothermic effect seen is assigned to the melting of the test item. Since the onset temperatures in both tests deviate by more than 0.5 K from their mean value of -34.05 °C, the test item has a melting range of -33 to -35 °C.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
