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:
- 2012-04-03 till 2012-10-02
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: DIN EN 14370
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- (adopted, 27th July 1995)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- (adopted, May 2008)
- Deviations:
- no
- Principles of method if other than guideline:
- Surface tension at 20°C:
The surface tension is determined using a plate tensiometer. A commercially available tensiometer based on the plate methode is used to measure the force which is required to withdraw a horizontally suspended plate from the surface of the test material or its solution in water. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- plate method
- Surface tension:
- 67 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of the test item was measured σ = 67.0 mN/m at 20 °C and a concentration of 1 g/L.
- Executive summary:
Surface tension of the test item was determined according DIN EN 14370 (OECD 115 and method A.5) and was measured by the plate method using a tensiometer at σ = 67.0 mN/m at 20 °C and a concentration of 1 g/L.
