jcgm-wg1 mission


Working Group 1 (WG1) of the Joint Committee for Guides in Metrology (JCGM) has responsibility for maintaining the Guide to the Expression of Uncertainty in Measurement, which is now used worldwide at all levels of the measurement chain, from NMIs to industry, under the name JCGM 100:2008 (GUM 1995 with minor corrections).

In addition, the JCGM-WG1 has decided to broaden the scope of the GUM by producing a series of complementary documents to cover some topics of interest in more detail. In this new perspective, JCGM100:2008 and the entire series of complementary documents are part of the GUM, which encompasses the whole suite of documents.

Please refer to the GUM Newsletter for information on the latest publications and documents in preparation.
