Applicant's summary and conclusion

Conclusions:
The Surface Tension of Suberic Acid is determined as 64.9 mN/m ± 0.2 mN/m at test temperature (20 ± 0.5 °C).
Executive summary:

The Surface Tension of Suberic Acid was determined by ring method at 20 ± 0.5 ºC. The solution thus formed was allowed to equilibrate at the test temperature (20 ± 0.5 ºC) using constant temperature water bath.

Three aliquots of the 1% w/v aqueous solution of Suberic Acid in analytical grade water were prepared. The average corrected surface tension value obtained from the three aliquots of the 1% w/v aqueous solution is reported as the surface tension of Suberic Acid.

The corrected surface tension of Suberic Acid is determined as 64.9 mN/m (± S.D. = 0.2) at test temperature (20 ± 0.5 °C).
