The CODATA 2014 values of the constants will be posted in Spring of 2015.
There will be an adjustment of the
constants to provide the values for a
revision of the
International System of Units (SI) expected to take place in 2018.
To be considered for use in this adjustment, new results must be
accepted for publication by 1 July 2017.
The 2018 CODATA adjustment of the fundamental constants will be based on the revised SI,
which will significantly affect the uncertainties of many constants.
For data to be considered for use in this adjustment, they must be
discussed in a publication preprint or a publication by 1 July 2018.
