Remarks on result:
not determinable

The test substance did not have a melting point in the temperature range of 30 - 400°C only an exothermic decomposition beginning at 250°C.

Conclusions:
The test substance did not have a melting point in the temperature range of 30 - 400°C only an exothermic decomposition beginning at 250°C.
Executive summary:

The melting point of the test substance was determined according to EU method A1 using the DSC.


The test substance did not have a melting point in the temperature range of 30 to 400°C. Only an exothermic decomposition starting at 250°C was observed.

Description of key information
