MEASUREMENTS OF THE VISCOSITY OF LIQUID R22, R124, AND R125 IN THE TEMPERATURE-RANGE 273-333-K AT PRESSURES UP TO 17-MPA

Viscosity masurements of refrigerants R22, R124, and R125 in the liqui d phase have been performed in the temperature range 273-333 K and al pressures up to about 17 MPa. A vibrating-wire instrument has been emp loyed. The overall uncertainty of the experimental values is estimated to be +/-0.5%. The experimental data have been represented by polynom ial functions of temperature and pressure for the purposes of interpol ation.
