Any other information on results incl. tables

The sample shows an endothermic boiling peak in the 283 - 307 °C region. The two measurements gave the following values:

The mean onset (rounded to 285 °C) is selected as giving the best value of the boiling point. The difference between the lower onset value and the higher peak value is used to estimate the uncertainty.

Applicant's summary and conclusion

Conclusions:
The boiling point of the test item is 285 ± 7 °C at 1001 hPa.
Executive summary:

The boiling point of the test substance was determined according to the OECD Guideline 103 using differential scanning calorimetry. At 1001 hPa, the boiling point is 285 +/- 7 °C.
