Remarks:
The mean values of 6 replicates from solution of the test item.
Conclusions:
The average surface tension of 6 replicates from solution of the test item was 70.403 mN/m at 20 ± 0.5 ˚C.
Executive summary:

The surface tension of the test item was determined with ring method at 20 ± 0.5˚C according to OECD Guideline 115 (Surface Tension of Aqueous Solutions). 1.00 g/L test item solution was prepared before measurement with pure water.

The average surface tension of the solution was 70.403 mN/m at 20 ± 0.5 ˚C.
