ASME PTC 19.11
The standard, titled "Steam and Water Sampling, Conditioning, and Analysis in the Power Cycle," is a critical guideline for ensuring the purity of the water and steam used in thermal power plants. It is widely used by engineers and chemists to design systems that monitor cycle chemistry and protect expensive equipment like turbines and condensers. Interesting Feature: Isokinetic Sampling
Typical application areas
1. Scope & Definitions
- Choose appropriate k (often based on degrees of freedom using Welch–Satterthwaite if needed).
- Compute expanded uncertainty = k × combined standard uncertainty.
What does ASME PTC 19.11 cover?
- Produce a one-page uncertainty budget template tailored to a specific test (specify measurand), or
- Draft a sample test-report section showing how to present uncertainty per PTC 19.11.
Post Body:
The standard provides highly technical specifications to prevent common sampling errors that can lead to equipment corrosion or scaling. ASME PTC 19.11: Steam & Water Analysis | PDF - Scribd
