Abstract
Data for the viscosity and thermal conductivity of gaseous and liquid argon have been evaluated and represented by empirical functions. Tables for the viscosity from 86 to 500 K for pressures to 400 MPa, and for the thermal conductivity from 90 to 500 K for pressures to 200 MPa are presented. For the viscosity, uncertainties of 2% or better for pressures below 100 MPa, and 3% for higher pressures are assigned. For the thermal conductivity the uncertainties are 4% for temperatures below 150 K and 3% or better for temperatures above. The enhancement in the conductivity close to the critical point has been accounted for. The status of the argon transport data and the philosophy of fitting them are reviewed.Keywords
