Any other information on results incl. tables
The vapour pressure of the test substance was found to be 0.012 Pa at 20°C and 0.018 Pa at 25°C.
The full results are shown inTable 4 (attached).
The Ln VP vs 1/T plot is shown in Figure 13 (attached).
There were no differences between the IR spectra for the untested, control and tested material; the comparative spectra are shown in Figure 14 to Figure 22 (attached). Therefore the test substance was unchanged during the test.No claim of GLP compliance will be made for the IR data but as it has simply been used as qualitative data to confirm stability of the test substance by comparison of spectra it has been reported here.
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test substance was determined to be 0.012 Pa at 20 °C, under the conditions of the test.
The vapour pressure of the test substance was determined to be 0.018 Pa at 25 °C, under the conditions of the test. - Executive summary:
In this guideline (OECD 104) study, [conducted with GLP certification], the vapour pressure of the test substance was determined to be 0.012 Pa at 20 °C, and 0.018 Pa at 25 °C, under the conditions of the test.
