The primary goal of this code is to ensure the accuracy and reliability of samples taken from thermal power generation systems. It provides specific guidance for:
Sample Selection: Identifying the best points in the power cycle to extract representative samples.
Sample Conditioning: Methods for cooling, condensing, and regulating the flow of high-temperature/pressure fluids to protect analytical instruments.
Isokinetic Sampling: Requirements for using specialized nozzles to ensure samples represent the true concentration of dissolved and suspended constituents.
Performance Monitoring: Guidelines for continuous chemistry monitoring and on-time acceptance testing for turbines, condensers, and deaerators. Official Access & Purchase Options

PTC 19.11 - Steam and Water Sampling, Conditioning ... - ASME
ASME PTC 19.11, officially titled "Steam and Water Sampling, Conditioning, and Analysis for Power Cycles," is a critical code for power plant engineers, chemists, and commissioning agents. It establishes standardized methods for:
The standard is frequently referenced in combined cycle, coal-fired, and nuclear power plants, as well as in industrial boiler operations.
Many universities subscribe to the ASME Standards Collection via engineering libraries. Students and faculty can download PTC 19.11 free through their campus portal.
ASME offers a lower-cost “read only” online access for some codes (around $25–60 vs. $150+ for downloadable PDF). You can browse but not print or save.
Older versions (e.g., 2005 or 2011) are sometimes sold at reduced cost on eBay or used book sites. But verify the revision is still acceptable for your application – power plants generally require the latest revision (2020 or newer).
