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: Secondary citation, but by peer-reviewed and recognized source. The test could have been exempted according to Annex VII in absence of prevision of tensio-activity and because this is not a wished property of the substance.
