The International Association for the Properties of
Water and Steam
IAPWS is an international non-profit association of national
organizations concerned with the properties of water and steam,
particularly thermophysical properties, cycle chemistry guidelines, and other aspects
of high-temperature steam, water and aqueous
mixtures relevant to thermal power cycles and other industrial and scientific
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 provide technical guidance, obtained by international consensus of
experts, on cycle chemistry and technology for
steam power cycles in fossil and combined cycle plants and other industrial applications.
(These are expressed in
IAPWS Technical Guidance Documents)
-
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). An Executive Committee,
consisting of the official representatives of all members,
conducts the general business at an annual meeting. IAPWS is governed by a set of
Statutes and Bylaws.
Note that IAPWS does not endorse or promote commercial products or entities; see the
By-Laws
for restrictions on the use of the IAPWS name and logo for commercial purposes.
Interested individuals, whether or not they reside in a member country of IAPWS,
are welcome to participate in the various IAPWS
Working Groups.
Current Members are Australia, Britain and Ireland,
Canada, the Czech Republic, Germany, Japan, New Zealand,
Russia, Scandinavia (Denmark, Finland, Norway, Sweden), and the United States,
plus Associate Members Argentina & Brazil, China, Egypt, France, Greece, India, Italy, and Switzerland.
