AbstractA simulation approach is described for testing the performance of uncertainty calculations based on the Guide to the Expression of Uncertainty in Measurement (GUM) 1st edn (Sèvres, Paris: BIPM Joint Committee for Guides in Metrology). Performance is measured in terms of the long-run success rate of an uncertainty calculation when applied to many simulated independent measurements. An individual calculation is deemed successful if the uncertainty interval obtained covers the measurand used in the simulation. Several examples, including two from the GUM, illustrate the approach. Software implementing the method is described in detail. Simulation is a practical method that can provide useful insights into specific measurement problems when there is any doubt about the validity of GUM calculations. © 2011 IOP Publishing Ltd.
