Data were obtained using a spherical resonator for two isotherms T = (273.16 and 250.00) K and pressures up to 8 MPa. The uncertainty study is detailed and the total uncertainty of the speed of sound is no worse than 0.01%. Heat capacities and acoustic virial coefficients were obtained through said measurements. Results are compared with the GERG-2008 equation of state. PB Elsevier SN 0021-9614 YR 2016 FD 2016 LK http://uvadoc.uva.es/handle/10324/29103 UL http://uvadoc.uva.es/handle/10324/29103 LA eng NO J.
