No vapour pressure could be determined experimentally. The result is stated as < 1.27*10e^-5 Pa at 354 K . The calculated value represents the behaviour of the test item at 81 °C; at lower temperatures,even lower limits for the vapour pressure should be expected.
The vapour pressure ofthe
test itemwas determined following EU
A.4 IOECD 104 by the effusion method (weight loss).
The test item was examined at five different
temperatures. Only the lowest chosen temperature (81 °C) had no
influence on the stability of the test item, at all other temperatures,
signs of decomposition were detected. Therefore, only the values fram
the fourth experiment could be taken into account.
No weight loss was detected, and it was
decided to calculate an upper limit for the vapour pressure, using the
smallest detectable difference in weight and the elapsed time.
The calculated value represents the
behaviour of the test item at 81 °C; at lower temperatures,
even lower limits for the vapour pressure
should be expected.
For the test item, no vapour pressure could
be determined experimentally.
The result is therefore stated as "< 1.27*10e^-5
Pa at 354 K"
