Introduction Every laboratory needs an uncertainty calculator if they plan to get ISO/IEC 17025:2017 accredited. According to section 7.6 of the ISO/IEC 17025:2017 standard, every testing and calibration laboratory must evaluate measurement uncertainty and include all contributions considered to be significant. This means that you need to estimate uncertainty and create uncertainty budgets […]
Propagation of uncertainty is an important aspect of uncertainty analysis. It is a method that transmits the uncertainties of independent variables through an equation to estimate the uncertainty of the final calculation. Commonly practiced in error and uncertainty analysis, the method is useful for estimating uncertainty where physical quantities cannot be measured directly. Indirect […]
