ASME PTC 19.1 is the American Society of Mechanical Engineers' standard for Test Uncertainty

• Digital Data Streams: How to handle uncertainty from virtual sensors and digital twins.
• Machine Learning Models: Quantifying uncertainty when AI predicts a value instead of a physical instrument.
• Bayesian Methods: As an alternative to frequentist statistics for short-duration tests.

ASME PTC 19.1-2018 (reaffirmed 2024) serves as the foundational standard for quantifying test uncertainty in mechanical engineering, outlining methodologies for separating random and systematic errors to determine measurement reliability. It is considered the industry gold standard for contractually determining performance guarantees for equipment, though its application requires high technical proficiency. For professional compliance, the updated standard is available through the ASME Store. PTC 19.1 - Test Uncertainty - ASME asme ptc 191 pdf
