Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was:
20°C 25°C
[Pa] [mm Hg] [Pa] [mm Hg]
Test item ≤ 8.1^10-8 ≤ 6.1^10-10 ≤ 2.0^10-7 ≤ 1.5^10-9
Note: the vapour pressure of the test item (which was, according to the method, extrapolated to 20°C and 25°C) could be slightly overestimated and is reported as less than or equal to values.
Executive summary:

The vapour pressure of the test item at 20°C (293K) is estrimate to be ≤ 8.1^10-8 Pa and ≤ 2.0^10-7 Pa at 25°C (298K)
