Results and discussion

Any other information on results incl. tables

From the results of the DSC measurements it was concluded that the test item had no melting point

under atmospheric conditions. The test item decomposed before melting (a starting point for the

decomposition cannot be given due to the broad endothermal effect during which the decomposition

started).

Applicant's summary and conclusion

Conclusions:
The test item had no melting point under atmospheric conditions. The test item decomposed before melting.
Executive summary:

The purpose of this study was the determination of the melting point of the test item according to:

European Commission Regulation (EC) No. 440/2008, A.1. Melting point / melting range.

The test item was tested as received. No further preliminary treatment such as drying or milling was performed. The results given in this report only apply to the tested sample.

The melting point / melting range is determined by differential scanning calorimetry (DSC). The test

item and the reference are heated up from ambient temperature to the final temperature at a

constant heating rate (10 K/min) in a defined atmosphere (nitrogen). Aluminium crucibles with a

small hole are used as containers for the test item and as empty reference crucible. The quantity of

heat absorbed or released is measured and recorded.

From the results of the DSC measurements it was concluded that the test item had no melting point

under atmospheric conditions. The test item decomposed before melting (a starting point for the

decomposition cannot be given due to the broad endothermal effect during which the decomposition started).
