Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- OECD harmonised ring method
- Surface tension:
- 66.38 mN/m
- Temp.:
- 20 °C
- Conc.:
- 9.9 mg/L
- Conclusions:
- The surface tension as corrected value is 66.38 mN/m measured at 20 °C. The concentration of the test solution was 9.9 mg/L.
- Executive summary:
The study was performed according to guideline A.5 for determination of the surface tension, EG Guideline 92/69 by the OECD ring method at 20 °C. The concentration of the test solution was 9.9 mg/L. The calibration factor (Phi b) of pure water at 20 °C was 0.9385. Corrected results of the surface tension for the first and second measurement (after 30 minutes waiting) were 66.38 mN/m and 67.04 mN/m. The surface tension as corrected value was 66.38 mN/m (average of the final three values). The substance is not surface-active and the deviation between the first and second measurement (0.99 %) is within the experimental error.
Reference
- Result first measurement: 66.38 mN/m
- Result second measurement: (after 30 minutes waiting/age of test solution 27 h. 30 min.): 67.04 mN/m
