AbstractKinematic viscosity data (ν) are presented for ethane‐1,2‐diol, for N, N‐dimethylformamide and for nine binary mixtures in the ‐ 10°C to 80°C temperature range. The experimental data were fitted by several empirical relations such as Grunberg‐Nissan (1949), McAllister (1960), Heric (1966), Lobe (1973), Auslander (1964) and polynomial equations. Some considerations regarding the meaning of the obtained adjustment parameters are made. Furthermore, a new best fit equation is proposed and its validity has been compared to that of the other relations on the basis of the reproducibility of the exper
