WebFor example, ASME standards are used to address the role of measurement uncertainty when accepting or rejecting products based on a measurement result and a product specification, provide a simplified approach (relative to the GUM) to the evaluation of dimensional measurement uncertainty, resolve disagreements over the magnitude of … WebJCGM 100 series – Guides to the expression of uncertainty in measurement (GUM series) Two people measuring the same product with the same ruler on different days would probably get different results. This could be because of factors such as a change in the room temperature (important for a metal ruler) or different eyesight capabilities.
WebDec 1, 2024 · For example, consider a model that converts measurements units such as meters to centimeters: f(X) = aX. Using 7.3 the variance of f(X) is a 2 Var(X) = a 2 u 2 (x). Therefore, the uncertainty of the converted value is the uncertainty of the measurement of x in original units multiplied by the units conversion factor a.
