Test Data Measurement Uncertainty Analysis

The Structural Validation Branch (AFRL/RQVV) is a research and development test organization that supports internal (Air Force) and external customers. The calculation of test data uncertainty is a necessary capability for a test organization. Test data uncertainty analysis provides error limit values based on the combined effects of random and systematic error sources. The measurement uncertainty calculations provide a means to characterize the measurement methods and understand what the test data represent. This allows engineers to make informed decisions based on the quality of the test data. Error source examination can also be used to determine if corrective actions are necessary and/or possible to eliminate or reduce measurement errors. AFRL/RQVV has completed a project to develop the procedures and tools to calculate and document test data measurement uncertainty values.
