Conditioning water samples that exceed 500°C and 250 bar involves serious safety risks. ASME PTC 19.11 acts as a safety manual alongside its analytical guidelines: Adjusting sample temperature and pressure to safe levels

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.
