The massic heat capacity cp = (1h/1T)p of 1,2,2,2-tetrafluoroethane (refrigerant R134a) was measured at 18 temperatures from 253 K to 523 K at pressures between 40 kPa and 30 MPa. The Joule-Thomson coefficient mJT = (1T/1p)h of this substance was measured at six temperatures from 333 K to 423 K at p

The massic heat capacity values c p of CFCl 3 and CF 2 ClCFCl 2 and of (0.5CFCl 3 + 0.5CF 2 ClCFCl 2 ) were measured with high accuracy with a flow apparatus. The results for the pure substances were published in an earlier paper. The present paper contains the results for the mixture. The density o
