Abstract The gaseous viscosity of nitrous oxide (N2O) was measured in the critical region. The experimental temperature range was between 309.650 and 318.150 K and the pressure range was up to 9.6 MPa. The measurements were obtained with an oscillating-disk viscometer, combined with local determination of the density at the position of the oscillating disk, and they have an estimated accuracy of 0.6 % for viscosity and 0.5 % for gas density. The viscosity of N2O exhibits an anomalous increase near the critical point. The anomalous increase in viscosity was analyzed with the viscosity equation proposed by Basu and Sengers.
