Surface tension of solution 2
Value 2: 29.9 mN/m
Value 3: 29.6 mN/m
Value 4: 29.4 mN/m
Value 5: 29.6 mN/m
Value 6: 29.3 mN/m
Arithmetic mean value: 29.7 mN/m;
standard deviation 0.4 mN/m.
By adjusting the temperature setting of the
tensiometer, differences in the density of the liquid can be compensated
Arithmetic mean of two test solutions: 29.85
mN/m (+/- 0.21 mN/m)
Arithmetic mean value corrected by
calibration factor determined via water calibration: 29.9 mN/m
The surface tension of an aqueous test substance solution at ca. 250 mg/L was found to be 29.9 mN/m at 20°C. Because the surface tension is < 60 mN/m, the substance is regarded to be surface active.
Determined in a study performed in
accordance with OECD 115, using the ring method.
