The well-established ISO GUM (Guide to the Expression of Uncertainty in Measurement) method for evaluating measurement uncertainties refers to measurements where the properties of all involved quantities are assumed to be constant. In many technical applications, however, a time-dependent uncertainty information that can be attributed to values measured and filtered by dynamic systems is more and more needed, e.g. for closed-loop control. This contribution extends the existing ISO GUM method consistently to time-dependent quantities of dynamic systems in a straightforward way. For this purpose, state-space models are used, as this approach results in a method that is very close to the original ISO GUM. The method is demonstrated by using the example of a low-pass filter.
