test procedure in accordance with generally accepted scientific standards and described in sufficient detail
according to
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
adopted in 1981
according to
EU Method A.1 (Melting / Freezing Temperature)
Principles of method if other than guideline:
Internal procedure: SOP FO 3.31-4.1
GLP compliance:
Type of method:
capillary method
Melting / freezing pt.:
> 300 °C
The melting point of the substance is above 573 K (300 °C).
Executive summary:

The melting point of the substance was assessed according to the OECD Guidelines 102, EU Method A.1. and the internal procedure SOP FO 3.31 - 4.1.

No melting point was detected below 573 K (300 °C), after the application of the capillary method in liquid bath.


The melting point of the substance is above 573 K (300 °C).
