1.1This guide covers the methodologies and best practices for developing and reporting total measurement uncertainty (TMU) estimates for non-destructive assay (NDA) measurements, instruments, calculations, or systems while adapting the principles of JCGM 100 or GUM to meet the uncertainty quantification needs of NDA.
1.2Guidance is provided on testing and evaluating uncertainty estimates.
1.3This guide applies to neutron-, photon-, and heat-based NDA methods.
1.4Both stochastic modeling and analytical uncertainty estimation methods are covered.
1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
