Technical Guidance Documents have been developed by IAPWS to provide truly international guidance for all aspects of cycle chemistry for fossil and combined cycle plants. They represent the accumulated experience of members of the IAPWS Power Cycle Chemistry (PCC) Working Group with expertise from 15 countries.

A different type of IAPWS document is the IAPWS Certified Research Need (ICRN), which is a statement of the need for research on a specific topic. ICRNs are listed on a separate page.

All current IAPWS Technical Guidance Documents are listed below (with the most recent at the top) and are downloadable as PDF files.

• Phosphate and NaOH treatments for the steam-water circuits of drum boilers of fossil and combined cycle/HRSG power plants (September 2011)
• Volatile treatments for the steam-water circuits of fossil and combined cycle/HRSG power plants (July 2010)
• Instrumentation for monitoring and control of cycle chemistry for the steam-water circuits of fossil-fired and combined-cycle power plants (September 2009)
• Procedures for the Measurement of Carryover of Boiler Water and Steam (September 2008)
