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:
- 12 September 2006 - 6 October 2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- yes
- Remarks:
- see below
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: ISO 304 ring method
- Deviations:
- no
- Principles of method if other than guideline:
- Deviation: The surface tension result was not corrected using the Harkins-Jordan correction table as the correction is not applicable to the apparatus used. Once calibrated, the balance and ring assembly used in this test give a direct reading for surface tension that is within the required accuracy (± 0.5 mN/m); this is as a result of the reduced ring dimensions. This deviation has been considered not to have affected the integrity of the study.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Surface tension:
- 63 mN/m
- Temp.:
- 22.4 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of a 1.00 g/L solution of test substance has been determined to be 63.0 mN/m at 22.4 ± 0.5°C. The test substance is considered not to be a surface-active material.
