International Vocabulary of Metrology

The Joint Committee for Guides in Metrology (JCGM) has initiated the circulation for review of the first Committee Draft (CD) of the document JCGM 200, International Vocabulary of Metrology (VIM), 4th edition.

This document has been prepared by the Joint Committee for Guides in Metrology, of which IUPAC is a member, specifically by Working Group 2.

This document is now being circulated for review amongst the eight member organizations (BIPM, IEC, IFCC, ILAC, ISO, IUPAC, IUPAP, and OIML).

Together with the VIM4 CD, the WG2 experts have prepared a document in which the VIM4 CD and the current VIM3 can be easily compared and a document is which the main changes are listed and justified. The three documents are:
VIM4 CD compared to VIM3 JCGM-WG2-CD-02
Significant changes JCGM-WG2-CD-03
