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:
- 02.12. – 03 Dec 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Guideline compliant study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- ring method
- Surface tension:
- 72.6 mN/m
- Temp.:
- 20 °C
- Conc.:
- 0.018 g/L
- Conclusions:
- 72.6 mN/m
- Executive summary:
The surface tension was determined with the ring method according to EC A.5 and OECD 115. The surface tension of a 0.018 g/L solution of FeS was 72.6 mN·m-1.
The result is considered relevant and reliable for the further risk assessment.
- Endpoint:
- surface tension
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
- the study does not need to be conducted because water solubility is below 1 mg/L at 20°C

Additional information
In the Klimisch 1 key study (Paß 2011) the surface tension was determined with the ring method according to EC A.5 and OECD 115. The surface tension of a 0.018 g/L solution of FeS was 72.6 mN·m-1.
The result is considered relevant and reliable for the further risk assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
