Applicant's summary and conclusion

Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of the test substance. The vapour pressure at 20 °C (293 K) was 5.69x10^-4 Pa = 4.26x10^-6 mm Hg.
Executive summary:

The vapour pressure of the substance was determined according to OECD Guideline 104. The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of the test substance. The vapour pressure at 20 °C (293 K) was 5.69x10^-4 Pa = 4.26x10^-6 mm Hg.
