GUMkehyksen
GUMkehyksen, or the GUM framework, refers to the approach described in the Guide to the Expression of Uncertainty in Measurement (GUM). It provides a structured, internationally recognized method for evaluating and expressing the uncertainties attached to measurement results. The aim is to enable meaningful comparison of results and to establish traceability to the SI units.
At the core of the GUM framework is a measurement model y = f(x1, x2, ..., xn), where y
The standard uncertainty of the result, u(y), is obtained by propagating the input uncertainties through the
Results are reported with the measured value, the standard uncertainty, and the expanded uncertainty, together with
