For the purpose of revealing the rather complicated thermodynamic surface of ordinary water substance in the critical region, a series of measurements of the PVT properties and the vapor-pressures of this technically important fluid have been performed by means of a constant-volume method. Ninety-three PVT measurements along 14 isotherms between 638.15 K and 652.15 K have been completed covering pressures from 18.5 to 39.2 MPa and densities from 122 to 610kg/m3. Twenty-six vapor-pressure measurements have also been performed at temperatures between 620.15 K and 647.05 K in the near vicinity of the critical point. Our measurements are compared with other available experimental data as well as with several equations of state. We also propose a new vapor-pressure correlation from the triple point to the critical point.
