Thermographic Data

Thermal Event	Interpretation	Temperature
		Determination 1		Determination 2
		ºC	K	ºC	K
Endotherm	Phase transition Melting range	11.0 to 41.0	284 to 314	10.8 to 41.0	284 to 314

Mean melting range:  11 to 41 °C (284 to 314K)

Conclusions:

The melting point of the test item has been determined to be in the range of 11 to 41 °C (284 to 314 K).

Executive summary:

The determination was carried out by differential scanning calorimetry, using a procedure designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No.440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Conclusion

The melting point of the test item has been determined to be in the range of 11 to 41 °C (284 to 314 K).
