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:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
In accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.5, this study does not need to be conducted if the melting point is >300 C. An estimation of the vapour pressure was instead conducted by the ICI Fire and Explosion Hazards Laboratory and is presented in place of a definitive study.
