Road map for measurement uncertainty evaluation

Use of Pooled Standard Deviation of Paired Samples in Calculating the Measurement Uncertainty by the Monte Carlo Method

“…However, studies present some limitations of GUM: a) linearization of the model: the principle of uncertainties propagation applied by GUM, which deals with the calculation of the combined standard uncertainty, the Taylor series expansion is truncated to the firstorder terms. This linear approximation in some cases may require higher order terms; b) the assumption of normality of the measurand: according to the recommendation of the GUM, it is common practice to consider the normal distribution in the expression of the expanded uncertainty; Désenfant and Priel [9] highlight the laboratory difficulties for determining the measurement uncertainty, particularly in calculating the correlation between the input variables and the derivation from measurements mathematical models.…”

“…15 5 Anton Paar (DMA 5000) Ma et al [27] 293.15 333. 15 5 Anton Paar (DMA 4500M) (2) describes the propagation of uncertainty based on a first-order Taylor series expansion in which u 2 (y), zf/zx i , u 2 (x i ), and u(x i , x j ) are variance of the measuring result, partial derivative, variance of the input quantity x i and covariance between x i and x j [44].…”

Estimating uncertainty of measurements for cavitation detection in a centrifugal pump

“…Also an ISO-GUM [5], revised by ISO/IEC Guide [7], predicts that in most cases, type A may be used. To evaluate the measurement uncertainty, also other methods are available [8][9][10], but they are not discussed in this paper.…”
