ASME PTC 19.11 — Overview and Summary

What it is

ASME PTC 19.11 (Performance Test Code 19.11) is a standards document published by the American Society of Mechanical Engineers that provides recommended procedures, methods, and reporting requirements for the uncertainty evaluation of measured values in performance tests. It guides practitioners on estimating, combining, and reporting measurement uncertainty so test results are defensible, traceable, and comparable.

Scope and purpose

• Scope: Applies to measurement uncertainty assessment for variables commonly encountered in performance testing of power, energy, and mechanical systems (temperatures, pressures, flows, electrical quantities, fuel measurements, etc.).
• Purpose: To ensure consistent, transparent, and technically sound methods for quantifying uncertainty in test measurements and derived results, supporting credible performance assessments, contract compliance, and regulatory reporting.

• Multiply each input’s standard uncertainty by its sensitivity coefficient to obtain its contribution to output uncertainty.
• Combine contributions by RSS, including covariance terms if inputs are correlated.
