Results and discussion

Melting / freezing point
Melting / freezing pt.:
>= 515 - <= 517.2 K
Remarks on result:
other: Conducted at atmospheric pressure

Any other information on results incl. tables

Melting was observed to start at 515.7K and the final melting temperature was 517.2K.

Applicant's summary and conclusion

Conclusions:
Based on testing using the capillary method at standard atmospheric pressure, the melting point of the substance is 515.7 to 517.2K.
Executive summary:

The study was conducted by a recognised GLP accredited laboratory, although the study report makes no claim of GLP compliance. Testing was conducted in accordance with method A1 of EEC Directove 84/449/EEC and determined the melting point at atmospheric pressure is in the range 515 to 517.2K.
