Summary

Measurements of the surface tension for two kinds of CFC alternatives, ie, R123, and R134a, have been made by the differential capillary rise method (DCRM) and the vertical plate method (VPM). The uncertainty of temperature measurement by DCRM is estimated within more or less 20 milliK, whereas that by VPM within more or less 30 milliK. New correlations of the surface tension for R123 and R134a have also been proposed.
