ASME PTC 19.11-2008 (R2018) defines essential standards for steam and water sampling in power cycles, emphasizing representative, isokinetic sampling to protect equipment from corrosion and scaling. It provides mandatory guidelines for sample conditioning and continuous monitoring to ensure accurate chemistry data. The official document is available through the ASME Digital Collection.
The standard specifies maximum allowable delay times between extraction and analysis to prevent degradation of dissolved gases or pH shifts. For dissolved oxygen, the delay is measured in seconds.
