SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material:040802#
Key result
Decomposition:
yes
Decomp. temp.:
392.8 °C
Remarks on result:
not determinable
Remarks:
The material decomposes before melting and boiling

The test item was observed to undergo an endothermic event from 362 °C which based on observations during the test using the photocell detection test, was not an indication of melting.This was followed by a small exothermic reaction at 392.8°C. On completion of testing the sample had decomposed during the test.

Conclusions:
The substance decomposes before the melting temperature.
Executive summary:

The melting point assessment was evaluated using the DSC method, according to the EU A.1 test guideline. An exothermic reaction was significant of a decomposition of the test item before melting.
