Applicant's summary and conclusion

Conclusions:
The vapour pressure of the substance at 25°C ranged from 1.0E-04 Pa to 5.3E-04 Pa.
The vapour pressure of the substance at 20°C ranged from 4.8E-05 Pa to 2.7E-04 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. Three experiments were performed.

Vapour pressure values of the substance at 20°C and 25°C were calculated (extrapolated) from each of the three resultant vapour pressure regression curves. The vapour pressure of the substance was given as a range of the results obtained.

The vapour pressure of the substance at 25°C ranged from 1.0E-04 Pa to 5.3E-04 Pa.

The vapour pressure of the substance at 20°C ranged from 4.8E-05 Pa to 2.7E-04 Pa.
