Setting target uncertainty in the Validation of Measurement Proedures that Include Sampling (VaMPIS), using the Optimised Uncertainty approach

Peter Rostron

Abstract

Approaches to the validation of measurement procedures that include sampling have recently been published. They form a joint Eurachem / EUROLAB supplement to previous publications that focussed on validation of the analytical procedure only. These approaches require the use of a target measurement uncertainty that can be compared with the measurement uncertainty obtained by experiment. In situations where this target uncertainty is not known or specified in advance, the Optimised Uncertainty approach can provide a systematic method for calculating this value. A new program called OptiMU has been created to assist in these calculations. This is described using worked examples.
