Measurement uncertainty is the doubt about the true value of the measurand that remains after making a measurement [Possolo, 2015]. The corresponding margin of doubt is characterized by its width (size of the uncertainty) and by its depth (severity of the uncertainty): the wider this margin, the larger the range of values of the measurand
29 kwi 2020 · A principal source of dimensional uncertainty is the measurement equipment itself. This paper presents an activity model, rule types, and sample rules for selecting dimensional-metrology...
the publication in 1993 of the “Guide to the Expression of Uncertainty in Measurement” (the GUM) [H.2] by ISO in collaboration with BIPM, IEC, IFCC, ILAC, IUPAC, IUPAP and OIML, which formally established general rules for evaluating and expressing uncertainty in measurement across a broad spectrum of measurements.
This report was prepared by a Eurolab expert group on measurement uncertainty, affiliated to the Eurolab Technical Committee on Quality Assurance in Testing (TCQA), that was established for this purpose and disbanded after completing the work.
1 lis 2016 · The paper presents examples of the evaluation of uncertainty components in accordance with the current and revised Guide to the expression of uncertainty in measurement (GUM).
This suite of examples illustrates good practice in evaluating measurement uncertainty in a variety of fields including calibration, testing, comparison and conformity, and relate to sectors that include environment, energy, quality of life, industry and society.
The ‘Guide to the expression of uncertainty in measurement’ (GUM) establishes general rules for evaluating and expressing uncertainty in measurement from the shop floor to fundamental research.
