Abstract

A coaxial-cylinder apparatus has been designed for steady-state and for non-steady-state measurements. The cell was calibrated by using several gases of known thermal conductivity (air, helium). The thermal conductivity of Refrigerant 12 (R 12) in the liquid and gaseous states at temperatures up to 0.95 T_cr and at pressures to 16 MPa has been determined. Erratum to this paper appears in 3(1)
