Joint Committee for Guides in Metrology (JCGM)

The tasks of the JCGM are to maintain and promote the use of the Guide to the Expression of Uncertainty in Measurement (known as the GUM) and the International Vocabulary of Basic and General Terms in Metrology (known as the VIM). The JCGM has taken over responsibility for these two documents from ISO TAG 4, who originally published them under the auspices of the BIPM, IEC, IFCC, ISO, IUPAC, IUPAP and OIML. Click here for the JCGM Charter. The JCGM operates through two working groups: the JCGM-WG1, with responsibility for the GUM, and the JCGM-WG2, with responsiblity for the VIM.
