ASME PTC 19.2 — Fixed (Overview)

ASME PTC 19.2 is part of the Performance Test Codes (PTCs) series and provides standardized procedures and reporting formats for conducting performance tests and presenting results. When you specify "Fixed" in the context of PTC 19.2, it typically refers to the fixed-format test report forms and prescribed presentation style the code requires for documenting test data, calculations, uncertainties, and conclusions.

  • Fixed installation requirements (permanent piping taps)
  • Fixed reference conditions (static vs. dynamic pressure)
  • Fixed uncertainty calculations (systematic vs. random errors)
  • Issue: Main steam pressure transmitter had a 3-year-old calibration; drift was +0.8% of span.
  • Hydrostatic correction missing: Transmitter was 4.5 m below tap, impulse line water-filled, no correction applied → 44 kPa error.
  • Resulting uncertainty: Total ( U_95 ) was ±1.1%, exceeding PTC 6’s required ±0.25% for pressure.

| Standard | Focus | Fixed Tap Allowed? | | :--- | :--- | :--- | | ASME PTC 19.2 | General pressure measurement for performance tests | Yes (primary focus) | | ASME PTC 6 | Steam turbine testing (refers back to PTC 19.2) | Yes, with additional requirements | | ISO 5167 | Differential pressure flow meters (orifice plates) | No (requires corner taps or flange taps) | | API 551 | Process measurement (not performance testing) | Yes, but less stringent | asme ptc 192 fixed

  • Bourdon tube gauges
  • Diaphragm seals
  • Capacitance manometers
  • Strain-gauge pressure transducers
  • Digital pressure indicators
