Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item was estimated to be 9.14*10-5 Pa at 25°C based upon a calculated boiling point of 334°C.
Executive summary:

In a previous study the boiling point of the test item was not able to be measured. As such the boiling point of the test item was calculated using the Meissner's method to be 334 °C. The vapour pressure of the test item was then calculated using the Modified Watson Correlation method to be 9.14*10 -5 at 25 °C.
