Applicant's summary and conclusion

Conclusions:

The vapour pressure of the substance at 20°C was determined to be 1.2E-3 Pa.
The vapour pressure of the substance at 25°C was determined to be 2.3E-3 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 constants specific for the experimental arrangement were determined using a set of 5 reference compounds. A vapour pressure curve for the test item was constructed from duplicate measurements at 80°C, 90°C, 100°C and 110°C. The vapour pressure of the substance at 20°C and 25°C was determined by extrapolation to be 1.2E-3 Pa and 2.3E-3 Pa, resp.
