N2 - In this paper, 182 pvTz data (28 data in the two-phase region and 154 data in the superheated vapor region) of mixtures containing difluoromethane (R32) and trans-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(E)) are reported. The measurements were carried out along 10 isochores (0.013173, 0.039422, 0.043115, 0.046522, 0.062966, 0.068225, 0.068959, 0.110447, 0.115156, and 0.121732 m3·kg-1) in the temperature range from 263 to 373 K for 10 R32 mole fractions (0.1677, 0.2360, 0.2551, 0.4634, 0.5374, 0.6715, 0.7383, 0.7544, 0.9532, and 0.9533). The flash method with three equations of state (EoSs) was used to assess the vapor-liquid equilibrium of the binary mixture under analysis. The calculated vapor-liquid equilibrium behavior for the R32 + R1234ze(E) binary system agreed with the experimental data collected from the open literature. The vapor-phase measurements were correlated through the aforementioned EoSs and a truncated virial EoS. These pvTz points agreed with both the values provided by the EoSs and REFPROP 10.0.
