NF ISO/IEC GUIDE 98-1, X07-040-1 (05/2024)

This document establishes general rules for the evaluation and expression of measurement uncertainty for measurements from the trader's shop to fundamental research. Therefore, the principles of this series of documents are intended to apply to a broad spectrum of measurements and their applications. An overview of the parts of the GUM is provided in Table A.1 in Annex A. NOTE When the acronym GUM is used in this document, it refers to the series of documents. An individual part of the GUM is designated by its corresponding JCGM number (for example, Part 6 of the GUM is designated JCGM GUM-6:2020). This document provides a rationale for the evaluation, expression and use of measurement uncertainty (Clause 2). It presents a brief introduction to measurement (Clause 3) and the decisions involved in assessing measurement uncertainty (Clause 4). Clause 5 provides a brief description of the content of the parts of the GUM. In each of these articles, relevant parts of the GUM are identified to provide additional guidance.
