Applicant's summary and conclusion

Conclusions:
The vapour pressure at 25°C was determined to be 4.6E-08 Pa.
The vapour pressure at 20°C was determined to be 1.8E-08 Pa.
Executive summary:

The vapour pressure of the substance was determined using the isothermal thermogravimetric effusion method in a GLP study according to EC A.4, OECD 104 and OPPTS 830.7950. The vapour pressure at 25°C was determined to be 4.6E-08 Pa. The vapour pressure at 20°C was determined to be 1.8E-08 Pa.
