Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose:
reference to same study
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
yes (incl. certificate)
Remarks:
Ministero della Salute, D.G. Della Prevenzione Sanitaria Officio IV, Milan.
Type of method:
differential scanning calorimetry
Remarks on result:
not determinable
Remarks:
No thermal effects could be assigned to a melting point.

Results

In the first and second test the heat flow record shows a series of exothermic and endothermic effects. No thermal effect can be assigned to a melting point.

 

Conclusion

A series of exothermic and endothermic effects occurred before the melting point. The melting point of the sample cannot be measured.

 

Description of key information

No thermal effects could be assigned to a melting point up to a temperature of 500 °C (Differential scanning calorimetry, OECD 102)

Key value for chemical safety assessment
