Administrative data

Endpoint:
vapour pressure
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Justification for type of information:
It is not possible to measure the vapour pressure of this substance using standard methods. A calcuation method, using an accepted model, was used instead.
