1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
GLP compliance:
yes
Type of method:
OECD harmonised ring method
Key result
Surface tension:
61.4 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
Under the study conditions, surface tension of an aqueous solution of the test substance was established at 61.4 mN/m (average value) at 20°C. The change of the surface tension during the test was very small.
Executive summary:

A study was conducted to determine the surface tension of the test substance according to EU Method A.5 (harmonized ring method), in compliance with GLP. Two tests were performed using a concentration of 1 g/L in water. Measurements were taken at 136 and 131 min. Under the study conditions, the surface tension of an aqueous solution of the test substance was established at 61.4 mN/m (average value). The change of the surface tension during the test was very small (Grosenick, 1997).

Description of key information

The surface tension was determined according to EU Method A.5 (harmonized ring method) (Grosenick, 1997).
