EC number: 213-651-2
CAS number: 998-40-3
The method is validated in the range 10-8 - 103 Pa using a set of five
reference substances with known vapour pressures. The validity of the
method was verified maximum one month before this study using
hexachlorobenzene as reference control substance. Since the logarithm of
the evaporation rate at 20°C (log vT, 20) deviated < 10% from the
average value obtained during the validation test, it was possible to
apply the constants obtained with the validation test for the
determination of the vapour pressure of the test item.
The vapour pressure of the test item at 20°C and 25°C was 0.019 hPa and
0.036 hPa, respectively.
