The standard outlines reporting formats that include:
You might ask, "We have digital transmitters now; does this old analog standard still matter?"
The answer is yes. The physics of pressure and the mathematics of uncertainty have not changed.
The code applies to the measurement of static pressure for fluids in closed conduits or open channels. It covers a wide range of pressures, from high-vacuum conditions to high-pressure hydraulic systems.
The significance of this code lies in its role as the "referee" method. When performance guarantees are contractually bound, PTC 19.2 provides the mutually accepted standard for determining whether pressure readings are valid and accurate.
ASME PTC 19.2 is the definitive industry standard for pressure measurement in performance testing. It bridges the gap between a generic pressure sensor data sheet and a reliable, low-uncertainty measurement system. By following its guidance on instrument selection, installation, calibration, and uncertainty analysis, engineers can achieve pressure measurements that meet the rigorous demands of thermal performance testing, energy auditing, and code compliance.
For any serious power plant, industrial process, or R&D laboratory requiring defensible pressure data, adherence to ASME PTC 19.2 is not optional — it is a prerequisite for valid test results.
If you truly intended a different standard number (e.g., ASME PTC 19.2, not 192), this is the correct document. If you recall a different title, please provide additional context, and I will adjust the response accordingly.
ASME PTC 19.2 (often referred to as ) is a supplement to the ASME Performance Test Codes that provides standardized instructions for pressure measurement instruments and apparatus What is ASME PTC 19.2?

Disclaimer: As of the current date, there is no published standard with the designation ASME PTC 192. The ASME Performance Test Codes (PTC) series currently ranges from PTC 1 through approximately PTC 61, with specific codes for various equipment.
It is highly probable that the intended designation was ASME PTC 19.2 (Pressure Measurement), which is part of the fundamental "PTC 19" series used to support other performance test codes.
Below is a comprehensive report based on ASME PTC 19.2-2010 (Performance Test Code – Pressure Measurement). If you intended a different standard or a specific draft revision, please verify the code number.
ASME PTC 19.2 categorizes pressure measurements into three classes based on the required uncertainty for a given performance test.
| Class | Typical Application | Maximum Permissible Uncertainty (95% confidence) | |-------|----------------------|------------------------------------------------------| | Class 1 | Research & development, code-required performance tests (e.g., heat rate tests) | ±0.1% of reading or better | | Class 2 | Acceptance tests, routine performance monitoring | ±0.25% to ±0.5% of span | | Class 3 | Operational checks, safety, trending | ±1.0% to ±2.0% of span |
Note: Uncertainty is expressed in terms of expanded uncertainty (k=2) per the ISO Guide to the Expression of Uncertainty in Measurement (GUM).
