NASA-HDBK-8739.19-3 Measurement Uncertainty Analysis Principles and Methods. NASA Measurement Quality Assurance Handbook - ANNEX 3

National Aeronautics and Space Administration (NASA). This Technical Handbook approved by NASA 07-13-2010. 275 p. The analysis methods outlined in this document provide a comprehensive approach to estimating measurement uncertainty. Basic guidelines are presented for estimating the uncertainty in the value of a quantity for the following measurement alternatives: -
- Direct Measurements – The value of a quantity is obtained directly by measurement and not determined indirectly by computing its value from the values of other variables or quantities.
- Multivariate Measurements – The value of the quantity is based on measurements of more than one attribute or quantity.
- Measurement Systems – The value of a quantity is measured with a system comprised of component modules arranged in series.
