Summary

The ultrasound velocity of the ozone-safe refrigerant R152a in a liquid phase in a temperature interval of 14-94 deg C and at presssures of 0,4-16 megapascals was measured with an error of 0.2%. In the one-phase field and in the saturation line, the experimental data were generalized by dependence based on a physical model. Tables of thermodynamic properties (density, isobaric heat capacity, thermal coefficients), calculated by the velocity of ultrasound and p,V,T-data are presented.
