Principal goals of the present work are to measure the viscosity of vapor and liquid cis1,1,1,4,4,4-hexafluoro-2-butene (R-1336mzz(Z)) and propose simplified correlations of the extracted data at saturation conditions for industrial design and simulation. R-1336mzz(Z), a hydro-fluoro-olefin with a low global warming potential and attractive environmental properties, can be considered as a potential working fluid for high temperature heat pumps and organic Rankine cycles. Nevertheless, reliable experimental R-1336mzz(Z) viscosity data are lacking. This study presents R-1336mzz(Z) viscosity data measured by a tandem capillary tube method at temperatures from 314 K (40.85 C) to 434 K (160.85 C) and 375 K (101.85 C) to 475 K (201.85 C) for liquid and vapor phases, respectively, at pressures up to 4.06 MPa. Total standard uncertainties in liquid and gas viscosity measurements were lower than 3.04 % and 3.21 %, respectively.
