Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 20/07/2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The pendant drop method for measurement of surface tension is accepted by OECD guidelines
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Principles of method if other than guideline:
- The pendant drop is a drop suspended from a needle in a bulk liquid or gaseous phase. The shape of the drop results from the relationship between the surface tension or interfacial tension and gravity. In the pendant drop method, the surface tension or interfacial tension is calculated from the shadow image of a pendant drop using drop shape analysis.
- GLP compliance:
- no
- Type of method:
- other: pendanr drop method
- Specific details on test material used for the study:
