. This standard provides the industry-recognized procedures for evaluating and reporting the uncertainty of measurement data in performance test codes. The current version of this standard can be found on the official ASME website

Note: Always ensure you are using the latest edition (e.g., 2018 or later) to ensure compliance with current standards. : Helping owners and contractors manage financial risks

One of the standard's key strengths is its flexible and comprehensive framework for classifying sources of uncertainty. It establishes two parallel, dual classification systems, allowing the engineer to choose the most appropriate perspective for any given analysis.
