Abstract: | The “Guide to the expression of uncertainty in measurement” (GUM) is an extremely important document. It unifies methods for
calculating measurement uncertainty and enables the consistent interpretation and comparison of measurement results, regardless
of who obtained these measurements and where they were obtained. Since the document was published in 1995, it has been realised
that its recommendations do not properly address an important class of measurements, namely, non-linear indirect measurements.
This drawback prompted the initiation of the revision of the GUM in the Working Group 1 of the Joint Committee for Guides
in Metrology, which commenced in October 2006. The upcoming revision of the GUM provides the metrological community with an
opportunity to improve this important document, in particular, to reflect developments in metrology that have occurred since
the first GUM publication in 1995. Thus, a discussion of the directions for this revision is important and timely. By identifying
several shortcomings of the GUM and proposing directions for its improvement, we hope this article will contribute to this
discussion.
