of vapour pressure (mean of three determinations (three flow rates)):
Pa at 30°C

data, the vapour pressure curve and the regression parameters are
provided in the experimental report.
linearity of the detector response with respect to concentration was
assessed over the concentration range of 2.92 to 29.2 mg/L (n=5). This
was satisfactory with a correlation coefficient of 1.000 being obtained.
of sample solutions from traps 1 range between 12 and 44 mg/L (no
substance detected in traps 2); some are slightly above the calibration
range , however, regarding the low standard deviations obtained with the
different flows, inaccuracy is considered negligible.
ensure saturation control, three different flow rates were used at each
temperature. From the data, it can be clearly seen that higher flow
rates did not lead to lower vapor pressures, which means that the
nitrogen was saturated with test item under the conditions of the test.
The vapour pressure of the test substance
was measured under GLP according to OECD 104 / EU A4 guideline, gas
Determinations were conducted at 30, 40 and
50°C, with three flow rates per temperature. Mass of evaporated test
item was quantified by GC.
Vapour pressure at 25°C was extrapolated to
be 0.249 Pa from the regression.
Closely extrapolated result from experimental measurements.Low volatility.
A fully reliable experimental study,
conducted according to a recognized OECD/EC method and under GLP, is
available. Therefore, it is considered as a key study. The result is
retained as key data.
