A Note on the XIX IMEKO World Congress Fundamental and Applied Metrology

This paper is a continuation of the article “A Critical Note on the Guide to the Expression of Uncertainty in Measurement (GUM)” published in Economic Quality Control 23. Unfortunately, the critique expressed on the GUM in that paper has so far been ignored by the metrology community. This paper shall illustrate and discuss the flawed use of statistical terms and methods in metrology. The GUM was published more than a decade ago, and undergoes presently a revision. Therefore, it is to be hoped that the here discussed weak points might be avoided in a new version of the GUM.
