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 of the test item is between 200°C and 300°C. According to Annex VII (section 7.5.) of Regulation (EC) No 1907/2006 a value based on a recognised calculation method is sufficient.
