Understanding ASME PTC 19.1: The Gold Standard for Test Uncertainty

Ensure test reports meet ASME compliance requirements.

In the world of performance testing, precision is not just a goal—it is a legal and financial requirement. Whether you are testing a power plant’s heat rate, a pump’s hydraulic efficiency, or a fan’s air flow, your raw data is useless without a statistical framework that defines its reliability. This framework is codified in the . asme ptc 191 pdf

: Offering a uniform method for comparing test results across different laboratories and facilities. Key Components of Uncertainty Analysis

The most up-to-date version is ASME PTC 19.1-2018 (R2024) . This reaffirmation in 2024 confirms that the 2018 edition remains the current, valid version. Understanding ASME PTC 19

The primary goal of the document is to define methods for estimating the interval within which the "true value" of a measurement is expected to lie. National Laboratory of the Rockies (NLR) (.gov) Measurement Evaluation

, titled "Test Uncertainty," is a foundational Performance Test Code (PTC) supplement published by the American Society of Mechanical Engineers (ASME)

The primary objective of ASME PTC 19.1 is to provide a standardized method for testing the performance of pressure transmitters. This involves evaluating their accuracy, response time, and other performance characteristics under controlled conditions.

If you have landed on this page searching for the term you are likely looking for the industry gold standard in performance test code uncertainty analysis. However, a critical correction must be made first: There is no ASME PTC 191.

ASME PTC 19.1 is titled "Test Uncertainty." It is part of the American Society of Mechanical Engineers (ASME) Performance Test Codes (PTC) series. While individual PTCs (like PTC 6 for steam turbines or PTC 22 for gas turbines) tell you how to run a test, PTC 19.1 tells you how trustworthy your results are.
