Verification of Software Applications for Evaluating Interlaboratory Comparison Results

Abstract

One of the main tasks of the international metrology system is to assure comparability of measurement results. It can be achieved through recognized traceability chains, which are linking measurement results to references such as measurement units and their realizations. However, the traceability is most commonly limited to measurement instruments and standards of measurement. Since modern measurement applications often use complex software for calculating final results from experimental data, it is very important that all computational links are recognized explicitly and known to be operating correctly. In order to introduce a traceability chain into metrology computation, European project EMRP NEW 06 TraCIM was agreed between EC and European metrology association Euramet. One of the tasks of the project is also to establish random datasets and validation algorithms for verifying software applications for evaluating interlaboratory comparison results. The aims and theoretical approaches of this task are presented in this paper. Background normative documents, calculated statistical parameters, boundary conditions for creating reference data sets, as well as customer interface are described. The verification application will be available on the project web page after finishing the project.
