The surface tension of trifluoroiodomethane (CF3I) has been measured in the present work. The measurements were conducted under equilibrium conditions between the liquid and its saturated vapor. Thirty data points have been obtained by differential capillary rise method (DCRM) in the temperature range from 243 to 344 K. The temperature uncertainty is within +/- 10 mK. The accuracy of surface tension measurements is estimated to be within +/- 0.1 mN m(-1). The correlation of surface tension also has been proposed, the RMS deviation is 0.58%.
