IAPWS is an international non-profit association of national organizations concerned with the properties of water and steam, particularly thermophysical properties and other aspects of high-temperature steam, water and aqueous mixtures that are relevant to thermal power cycles and other industrial applications. IAPWS objectives are

To provide internationally accepted formulations for the properties of light and heavy steam, water and selected aqueous solutions for scientific and industrial applications. (Official documentation of these formulations is under the Releases and Guidelines section of this website)
To define research needs and promote and coordinate research on steam, water and selected aqueous systems important in thermal power cycles
To collect and evaluate the resulting data, and to communicate and promulgate the findings
To provide an international forum for exchange of experiences, ideas and results of research on high-temperature aqueous media

IAPWS is organized as an association of member countries (or groups of countries). Its highest authority is the general meeting, usually held in conjunction with International Conferences on the Properties of Water and Steam. An Executive Committee, consisting of the official representatives of all member countries, conducts the general business at an annual meeting. IAPWS is governed by a set of Statutes and Bylaws.

Interested individuals, whether or not they reside in a member country of IAPWS, are welcome to participate in the various IAPWS Working Groups.

Current Member countries are Argentina and Brazil, Britain and Ireland, Canada, the Czech Republic, Denmark, France, Germany, Greece, Italy, Japan, Russia, and the United States, plus Associate Member Switzerland.
