175 Pressure, volume, temperature data points in gaseous phase for trifluoroiodomethane (CF3I) have been measured by means of Burnett/isochoric methods. Burnett expansion measurements were made both at 353.15 K and at 323.15 K. Based on the pressure-volume relationships established both at 353.15 K and at 323.15 K isotherms, data were collected along isochores. Data along eight isochores were measured in the temperature range 323.15 K-393.15 K. Data along five isochores were measured in the temperature range 278.15 K-323.15 K. The pressure range was 0.2-1.76 MPa. The maximum total temperature uncertainty in this work is estimated to be within ±10 mK; the maximum total pressure uncertainty is estimated to be within ±500 Pa. The purity of the sample used was 99.95 with 3,4 ppm of water.
