Administrative data

Endpoint:
vapour pressure
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The melting point is between 200°C and 300°C, and therfore a recognised calculation method of the vapour pressure is sufficient in accordance with Column 2 of Annex VII Section 7.5.
