Before widespread adoption of PTC 19.11, sampling methods varied significantly between plants. This led to inconsistent data, questionable performance calculations, and safety risks. Without a standardized approach, a sample taken from superheated steam might flash into a two-phase mixture in the sampling line, giving completely misleading conductivity or pH readings.
The key goals of ASME PTC 19.11 are to ensure:
