Administrative data

Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The reliability is rated 2 because the method of the study is similar to the standard guideline of reference (OECD 115), which describes a proceduredesigned to evaluate this endpoint, the results were reviewed for reliability and assessed as valid. Nonetheless the study was not conducted under GLP condition.
