Properties of saturated liquid heavy water, D2O, are given in this table as a function of temperature from the melting point to the critical point. Properties are calculated from formulations adopted for general and scientific use by the International Association for the Properties of Water and Steam (IAPWS). The background (including uncertainties) for the equation of state used for vapor pressure, density, and heat capacity is given by Herrig et al. (Ref. 1), and the background for the transport property correlations is given by Matsunaga and Nagashima (Ref. 2). The unpublished surface tension correlation and the other IAPWS formulations may be found on the IAPWS Web site <http://www.iapws.org>. The temperature scale is ITS-90. Additional calculations at state points not listed below can be obtained by using the NIST REFPROP program (Ref. 3) <http://www.nist.gov/srd/nist23.cfm>. Column definitions for the table are as follows.
