Applicant's summary and conclusion

Executive summary:

The vapour pressure test was performed according to the OECD Guideline 104 (Vapour Pressure Curve), isothermal thermogravimetrical effusion method.

A value of the vapour pressure of the test item was determined using the data obtained between 170 °C and 200 °C. The vapour pressure of the test item was estimated to be 4.15 x 10-5 Pa at 20 °C.
