The new KCDB website (KCDB 2.0) is live.

The new KCDB website (KCDB 2.0) went live this morning (29 October 2019) with extended search facilities. The new web address is www.bipm.org/kcdb. It is now possible to search on CMCs and comparisons using a free-keyword search - quick search - or by using a predefined menu - advanced search. You may also filter on CMC approval dates, combine an advanced search with free key words, filter CMC measurand values and uncertainties numerically, sort results and export search results to a spreadsheet.

A user platform with restricted access for creating and reviewing CMCs, and registering comparisons, will open in November 2019.

A new statistical tool is planned for the beginning of 2020.
