Guidance for the use of repeatability, reproducibility and trueness estimates in measurement uncertainty estimation
TS 21748:2004 gives guidance for the evaluation of measurement uncertainties using data obtained from studies conducted in accordance with ISO 5725-2, and for the comparison of collaborative study results with measurement uncertainty obtained using formal principles of uncertainty propagation. TS 21748:2003 is applicable in all measurement and test fields where an uncertainty associated with a result has to be determined, but does not describe the application of repeatability data in the absence of reproducibility data. The recommendations in this document are primarily for guidance.
