Applicant's summary and conclusion

Conclusions:
Surface Tension = 22.6 mN/m at 23ºC (1 g/L solution)
The study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability).
Executive summary:

The surface tension measurement was made on a 1 g/L solution of the test substance in deionised water using a DuNOUY tensiometer. The surface tension at 23ºC was 22.6 mN/m.
