Surface tension:
37.1 mN/m
Temp.:
20 °C
Conc.:
0.2 g/L

First test solution (c=0.199 g/L), T = 20 deg C, age of solution = 99 min.

Arithmetic mean of 6 measurements = 37.4 mM/m; SD = 0.0 mN/m

Second test solution (c=0.298 g/L), T = 20 deg C, age of solution = 319 min.

Arithmetic mean of 6 measurements = 36.1 mM/m; SD = 0.1 mN/m

Conclusions:
Surface tension = 37.1 mN/m (0.2 g/L) at 20 deg C.
Executive summary:

The surface tension was measured according to EU Test Method A.5. The surface tension was 37.1 mN/m (0.2 g/L) at 20 deg C.
