The surface tension of binary mixture refrigerants propane (R-290) (1) + 1,1-difluoroethane (R-152a) (2) at three mass fractions of w1 = 0.2008, 0.3497, and 0.4922 was measured at temperatures from (248 to 328) K with a differential capillary rise method. The uncertainties of measurements for the temperature and surface tension were estimated to be within +- 10 mK and +- 0.2 mN*m-1, respectively. A correlation for the binary mixture refrigerant R-290 + R-152a was developed as a function of mass fraction.
