Results and discussion

Surface tension
Key result
Surface tension:
26.3 mN/m
Temp.:
20.1 °C
Conc.:
1 g/L

Any other information on results incl. tables

The test was repeated until the last five determinations had a standard deviation of no more than 0.1 mN/m. The surface tension was corrected with a calibration factor of 1.0203. The absolute deviation was 1.1 mN/m.

Applicant's summary and conclusion

Conclusions:
The surface tension of LMDT is 26.3 mN/m.
Executive summary:

The surface tension of LMDT was tested using the ring method. Two solutions of about 1 g/L LMDT in water were tested. The mean surface tension, with calibration correction, was 26.3 mN/m.
