Applicant's summary and conclusion

Conclusions:

The test material has been determined to loose a volatile component at 603 ± 1 K at 99.46 kPa. The remaining residue on completion of each determination (observed once the crucibles had cooled) was a soft wax, consistent with that of the initial test material. This confirmed that a significant proportion of the test material had a boiling temperature greater than 400°C (>673 K).

Executive summary:

Method:

The determination was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86, Method A2 Boiling Temperature of Council Regulation (EC) No 440/2008 of 30 May 2008.

Discussion:

The remaining residue on completion of each determination (observed once the crucibles had cooled) was a soft wax, consistent with that of the initial test material. This confirmed that a significant proportion of the test material had a boiling temperature greater than 400°C (>673 K).

Result:

Overall result: The test material lost a volatile component at 603 ± 1 K

Conclusion:

The test material has been determined to loose a volatile component at 603 ±1 K at 99.46 kPa. The remaining residue on completion of each determination (observed once the crucibles had cooled) was a soft wax, consistent with that of the initial test material. This confirmed that a significant proportion of the test material had a boiling temperature greater than 400°C (>673 K).
