Any other information on results incl. tables
On completion of the tests the crucible lids were removed. This revealed a yellow liquid residue. This was most likely the larger components of the test material that had not yet boiled. As the test material was initially colourless, the yellow colour of the residue may have indicated that some decomposition had occurred, but this was not evident in the thermograms. Therefore, no values for the decomposition can be quoted.

Applicant's summary and conclusion
- Conclusions:
- The test material has been determined to partially boil with decomposition from 679 ± 0.5 K at 104.54 kPa.
- Executive summary:
Method
The determination was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86, Method A2 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
Results
The test material has been determined to partially boil with decomposition from 679 ± 0.5 K at 104.54 kPa.
