Applicant's summary and conclusion

Conclusions:

The vapour pressure of the substance at 20°C was determined to be ≤ 1.4E-3 Pa.
The vapour pressure of the substance at 25°C was determined to be ≤ 3.7E-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. A vapour pressure curve was constructed from duplicate measurements at 60°C, 70°C, 80°C and 90°C. The vapour pressure of the substance at 20°C and 25°C was determined by extrapolation to be 1.4E-3 Pa. and 3.7E-3, resp. Since the weight losses of the test item were obtained with a temperature program of above the melting temperature of the test item, the vapour pressure of the test item could be slightly overestimated. The vapour pressure of the substance at 20°C and 25°C was therefore reported as ≤ 1.4E-3 Pa.and≤ 3.7E-3, resp.
