(Performance Test Code) is the industry-standard guide for determining Test Uncertainty in engineering measurements. It provides a rigorous mathematical framework to quantify how errors in individual measurements—like temperature or pressure—affect the final results of a performance test. Core Purpose and Scope
The heart of PTC 19.1 is the separation of uncertainty into two distinct types: asme ptc 191 pdf
The standard, officially titled Test Uncertainty , is the cornerstone for quantifying the quality and reliability of experimental data in engineering. It provides a rigorous, standardized framework for evaluating how individual measurement errors propagate into final test results, ensuring that performance guarantees—such as those for power plant efficiency—are mathematically sound and credible.
