3. Calibration and Uncertainty Calculations
The standard includes complex equations for uncertainty propagation. Having the PDF allows engineers to verify their software calculations against the official formulas.
Section 3: Sampling Equipment
Provides engineering specifications for:
- Isokinetic samplers (for wet steam).
- Condensing samplers (for superheated steam).
- Quenching systems (to prevent chemical reactions after sampling).
2. Rapid Cooling and Pressure Reduction
Hot steam or water (up to supercritical pressures) must be cooled to <40°C (104°F) and depressurized to near atmospheric before reaching the online analyzers. This is done via a sample cooler or sample conditioning panel.
