Reference
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Study period:
29 January 2009 - 10 September 2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: OECD guidelines followed and statement of GLP
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 104 (Vapour Pressure Curve)
Qualifier:
equivalent or similar to
Guideline:
EU Method A.4 (Vapour Pressure)
GLP compliance:
yes
Type of method:
effusion method: vapour pressure balance
Temp.:
25 °C
Vapour pressure:
0 Pa
Conclusions:
The vapour pressure of the test material has been determined to be 4.8 x 10-10Pa at 25°C.
Executive summary:

The 95% confidence limits for the vapour pressure over the 7 runs cover the range 5.1 x 10-13Pa to 4.4 x 10-8Pa. This relatively large range reflects the fact that the vapour pressure of the test material is very low and close to the limit of measurement by the vapour pressure balance.

The vapour pressure of the test material has been determined to be 4.8 x 10-10Pa at 25°C.

 

Description of key information
