GUM conformity of software products - a discussion from a software tester's perspective

Abstract

This paper describes how to assess GUM conformity of software products which claim to offer a GUM-compliant calculation of measurement uncertainties. To bridge the gap between the GUM guideline and the required test specification, an analysis of the GUM from the perspective of software testing is presented. Problems of testability and ambiguity of GUM statements are analysed in detail. The benefit and the limits of the developed validation procedure and test environment are outlined.
