By the ASME Research and Technology Committee on Water and Steam in Thermal Systems, Subcommittee on Properties of Steam

International standards for water and steam properties are set by the International Association for the Properties of Water and Steam (IAPWS). This book, like the previous Steam Tables which date back to 1967, was produced by the efforts of the Properties of Steam Subcommittee of the ASME Research and Technology Committee on Water and Steam in Thermal Systems.

This is a complementary reference to the ASME Steam Tables software published in 1999, based on the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam (IAPWS-IF97). It contains chapters on Units and Conversions, Thermodynamic Properties, Transport Properties,and other Properties and Formulations, as well as Appendices on Thermodynamic Property Formulation and Transport Property Formulations. This book also contains 50 tables and charts for quick and easy reference.  It contains both SI and US units of measurement.

This Second Edition presents the same properties of water and steam as the First Edition (published in 2000), with two exceptions. In 2007, the International Association for the Properties of Water and Steam (IAPWS) adopted a new formulation for the high-temperature Region 5, extending the upper pressure limit of validity of Region 5 from 10 MPa to 50 MPa in order to cover conditions that might be encountered in some proposed new power cycles. The new Region 5 formulation is reflected in new Tables S-4 and U-4. Also, in 2008, IAPWS adopted a new formulation for the viscosity of water and steam. This is reflected in new Tables S-8, S-10, U-8, and U-10, along with new Figures S-2, S-3, S-5, U-2, U-3, and U-5. 
 
A few typographical errors have also been corrected and some of the background text and references were updated.
