The electrical conductivity and viscosity of 1-hexyl-3-methylimidazolium bis(trifluorosulfonyl)imide, [C6mim] [(CF3SO2)2N], were measured at atmospheric pressure, between 270 K and 350 K, for samples with an amount of water not exceeding 200 ppm, as part of International Union of Pure and Applied Chemistry Project 2002-005-1-100. Water content was monitored before and after measurements, by coulometric Karl–Fisher titration. Special care was taken with ionic liquid manipulation in view of the measurement uncertainty budget. The uncertainties of the electrical conductivity measurements and of the viscosity measurements are estimated to be better than 2.0 % and 0.5 %, respectively. Results were compared with data from other authors, and all data were correlated as a function of temperature.
