The global warming is now one of the serious international concern should be tackled worldwide. HFC refrigerants, such as R410A, are categorized as the long lived green-house gasses. This paper presents the surface tension measurement data of HFO-1123 with GWP less than 1, and a binary mixture HFO-1123/HFC-32. The capillary constant and surface tension of those are measured across temperature range from 267 K to 307 K by a differential capillary rise with a propagated uncertainty ±0.3 mN m-1. Among the selected predicting methods, the correlations of Di Nicola et al. (2011) and Gharagheizi et al. (2012) show the best agreement to the measured surface tension of HFO-1123 alone. For HFO-1123/HFC-32, the correlation of Di Nicola et al. (2017) shows good agreement. To predict the surface tension HFO-1123/HFC-32, empirical correlation is proposed based on the measured data.
