The International Organization for Standardization (ISO) and the International Electrical (IEC) have published the first of a planned series of guidance documents on measurement uncertainty. ISO/IEC Guide 98-3-2008, Uncertainty of Measurement – Part 3: Guide to the Expression of Uncertainty in Measurement (GUM: 1995), is a reissue of the 1995 version with several minor corrections. The new guide is available in both paper and electronic form.
ISO/IEC Guide 98-3 establishes general rules for evaluating and expressing uncertainty in measurement that can be followed at various levels of accuracy in many fields—from the shop floor to fundamental research. It will be followed by the first of three supplements, ISO/IEC Guide 98-3/Supplement 1, Propagation of Distributions Using a Monte Carlo Method.
In addition, ISO/IEC Guide 98-1 is being prepared to promote the sound evaluation of measurement uncertainty through the use of GUM, and to provide an introduction to the supplements and other related documents.
