1.1. This guide describes the methodology and good practice for developing and reporting Total Measurement Uncertainty (TMU) estimates for Non-Destructive Assay (NDA) measurements, instruments , calculations, or systems.
1.2. This guide provides guidance to test, evaluate, and bound uncertainty estimates.
uncertainty quantification
This is to reestablish a previous a work item tha thas since expired:
5.1. In order to be useful a physical measurement or calculation must be assigned a justifiable and scientifically based statement of the associated total measurement uncertainty (TMU). The TMU is the fundamental statement of the quality of the measurement.
5.2. Constructing and verifying TMU budgets that are suitable for the end user is often a complex and specialist task. It is a crucial part of the measurement process and is important to understanding the limitations and acceptability of the results. This guide is intended to be a resource and reference for, amongst others, subject matter experts, those selecting an NDA approach, instrument operators, instrument designers, facility managers, instructors, regulators, and end users of NDA data
The title and scope are in draft form and are under development within this ASTM Committee.
