Administrative data

Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
The vapor pressure results in the first method is above 575 Pa. A complete analysis is in progess to define more precisely the vapor pressure.
