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:
- 19 Jan - 23 Mar 1993
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- 84/449
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Surface tension:
- 72.18 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.001 g/L
- Conclusions:
- The surface tension at 20°C is 72.18 mN/m (+/- 0.087 mN/m). The test substance is not surface-active.
- Executive summary:
The study was conducted to assess the surface tension. The study was conducted in accordance with EEC Method for "determination of the surface tension", Directive 84/449/EEC, method A.5. The surface tension at 20°C is 72.18 mN/m (+/- 0.087 mN/m). The test substance is not surface-active.
Reference
No time dependence of the surface tension was observed within a test period of 0 - 3 hours. The values of both measurements were therefore averaged. (= 72.2 +/- 0.087 mN/m).
Validity criteria for the measurement of the surface tension:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| The individual results, their arithmetic mean and the corrected mean; concentration of the solution should be stated. | Individual results, mean and corrected mean values including tested concentration are stated within the report. | yes |
| A solution of the substance is prepared in distilled water. The concentration of this solution should be 90 % of the saturation solubility of the substance in water; when this concentration exceeds 1 g/ L, a concentration of 1 g/ L is used for testing. | The water solubility of the test substance was >1g/L. Therefore, 1 g/L was used for testing. | yes |
