摘要：

The compressibility factors and vapor pressure have been measured on Refrigerant 502 by using a Burnett apparatus. Refrigerant 502 is a minimum-boiling azeotrope of Refrigerant 22 (CHClF//2) and Refrigerant 115 (CClF//2CF//3). The results on the compressibility factor cover the range of temperatures from 273 to 383 K and of pressures from 0. 12 to 12. 3 MPa corresponding to a pressures from 0. 12 to 12. 3 MPa corresponding to a density variation from 4 to 1035 kg/m**3. The experimental uncertainity of these 149 results was estimated to be plus or minus 0. 2%. Twenty-five measurements of vapor pressure were made for temperatures from 273 to 354 K with an experimental uncertainty of plus or minus 0. 05%. A correlation of vapor pressures was proposed for temperatures from 170 to 355 K.
