The Properties of Steam Committee, which has a history extending back to 1921, exists to advance and disseminate knowledge of the thermodynamic and physical properties of water, steam, and aqueous solutions. Standardized and reliable knowledge of these properties is vital in the design and operation of thermal power cycles, and is also important in many other industrial and research applications.
The Properties of Steam Subcommittee also serves as the U.S. National Committee to the International Association for the Properties of Water and Steam (IAPWS). The Subcommittee is responsible for implementing IAPWS property formulations in the United States.
In 1997, IAPWS adopted a new formulation for water's thermodynamic properties "for industrial use" (intended specifically for the steam power industry). This replaces the 1967 IFC formulation that has formed the basis for previous editions of the ASME Steam Tables.
The Subcommittee has prepared computer software implementing the new industrial formulation. This software, with accompanying documentation, is now available from ASME. The professional version of the software contains full source code and executable programs. Site licensing is available; contact InfoCentral for more details. For purchasers of Version 1.0.1 of this software, a free upgrade to Version 1.1 is available. A student version containing only the executable programs has been discontinued.
The companion book to this software (and successor to the familiar ASME Steam Tables) is the ASME International Steam Tables for Industrial Use, published in early 2000 (Second Edition published in 2009, Third Edition published in 2014). A description of the book and ordering information are here. Errata were issued for the First Edition; the Second Edition incorporates all the corrections in addition to reflecting revised IAPWS standards for the viscosity and for high-temperature (above 1073 K) thermodynamic properties.
A compact steam tables booklet has been produced, titled ASME Steam Tables: Compact Edition. At 32 pages, it is suitable for students and others who desire something smaller and less costly than the full-sized book. It is available from ASME Press in single copies and in bulk.
In 1995, IAPWS adopted a new formulation for water's thermodynamic properties "for general and scientific use." The U.S. implementation of that formulation (the NIST/ASME Steam Properties Database) is distributed by the Standard Reference Data office of NIST. A limited set of property calculations based on this formulation is also available from NIST on the Web at http://webbook.nist.gov/chemistry/fluid and a printed report with steam tables from this formulation is also available.
We gratefully acknowledge the Electric Power Research Institute (EPRI), which provides financial support for some of the Subcommittee's activities.
The Subcommittee meets twice a year. Spring meetings are usually held at National Institute for Standards and Technology (NIST) headquarters in Gaithersburg, Maryland. Fall meetings are sometimes held in conjunction with the International Water Conference. Following are the currently scheduled meetings:
November 16, 2017 - Orlando, FL (Venue TBD)
April 4, 2018 – NIST, Gaithersburg, MD
Contact the Subcommittee Chair for more information about meeting locations, times, etc. Minutes from recent meetings are available here.

UPGRADE TO STEAM TABLES SOFTWARE
Purchasers of Version 1.0.1 of the ASME Steam Properties for Industrial Use, Professional Version, are encouraged to upgrade to Version 1.1 of the Fortran source code. The new version fixes minor problems (unlikely to affect most users) that have come to light in Version 1.0.1.
To upgrade, simply download the .zip file containing 23 revised Fortran routines. These have been given a .fix suffix (which you may wish to change, depending on your compiler). You should then substitute these for the corresponding .for files received with Version 1.0.1 in the applications where you are using the ASME Fortran source code. Please replace all 23 files; while changes in some files were trivial, in others cases bugfixes required changing multiple files in concert.
These Errata only apply to the First Edition of the book. The Second Edition, published in 2009, incorporates all the corrections.
ASME Steam Tables for Industrial Use (CRTD-58. ASME Order #801543). This is the First Edition.
These Errata apply only to the first and second printings of the First Edition. The third corrected printing (March 2006) incorporates these corrections.
