5 kwi 2001 · Examples of sources of uncertainty in our field are the measurement of volumes, weighing, reaction temperature, purity of reagents, and value assigned to the calibrator. Also properties of the instrument used e.g. the size and tolerance of the cuvette, if the instrument uses more than one cuvette they may be different, the wavelength etc.
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).
expression of uncertainty near zero, new guidance on the use of Monte Carlo methods for uncertainty evaluation, improved guidance on the use of proficiency testing data and improved guidance on the assessment of compliance of results with measurement uncertainty.
28 wrz 2017 · This chapter presents and explains the most used methodologies for the evaluation of measurement uncertainty in metrology with practical examples.
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.
6 gru 2016 · Revised versions of the Guide to the Expression of Uncertainty in Measurement and International Vocabulary of Metrology are likely to explicitly endorse both error and uncertainty approaches, including both frequentist and bayesian statistical methods, in chemical metrology.
6 maj 2022 · This paper discusses the comparison of uncertainties in chemical measurements using case study examples. Depending on the context, both exact and approximate F -tests are used to compare the ratios of uncertainties, while in some cases the approach is to compare separate confidence intervals.
