Popis:	Binary and ternary mixtures of the refrigerants R32, R125, R134a and R143a are tested as substitutes for the widely used refrigerants R22, R502 annd R13B1. Experimental investigations of the phase equilibrium and the saturated liquid and vapour densities of several mixtures of these are presented. Additional experimental data for the pure refrigerant R125 are also given. Vapour-liquid equilibrium data were measured within a arnge of temperatures from 245K to 315K for mixtures, or 235K to 340K for R125. Comparisons with cubic equations of state of the Trebble-Bishnoi-Salim type and modified Hankinson-Brobst-Thomson liquid density correlations are discussed
