New KCDB website live
The new KCDB website went live on 29 October with extended search facilities. You may 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 advanced search with free key words, filter CMC measurand values and uncertainties numerically, sort results and export search results to a spread sheet.
A user platform with restricted access for creating and reviewing CMCs, and registering comparisons, will open in November.
A new statistical tool is planned for the beginning of 2020.
