Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
05 May - 15 October 2008
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.4 (Vapour Pressure)
Deviations:
no
GLP compliance:
yes
Type of method:
effusion method: isothermal thermogravimetry
Key result
Test no.:
#1
Temp.:
20 °C
Vapour pressure:
< 0.001 Pa
Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of the test substance. The vapour pressure of the test substance at 20°C (293K) was < 1.47 x 10^-3 Pa = < 1.10 x 10^-5 mm Hg.
