A surface light scattering (SLS) method was applied to investigate the saturated liquid dynamic viscosity and surface tension of trans-l-chloro-3,3,3-trifluoropropene (R1233zd(E)) and dodecafluoro-2-methylpentan-3-one (also known as Novec1230 and Novec649) at a temperature range from 303 to 403 K and 303 to 433 K, respectively. The typical expanded uncertainty (k = 2) of the saturated liquid dynamic viscosity and surface tension is 3% and 1.5%, respectively. The liquid viscosity and surface tension were correlated with a simple polynomial equation and van der Waals equation, respectively.
