CODATA ( eng. Committee on Data for Science and Technology - Committee for Data for Science and Technology; Russian abbreviation is [cod] ) - an interdisciplinary committee of the International Council on Science , established in 1966 and aimed at collecting, critically evaluating, storing and the search for important data for the tasks of science and technology.

In 1969, the CODATA Task Group on Fundamental Constants was established . Its purpose is to periodically publish an internationally accepted set of values of fundamental physical constants and coefficients for their translation. The first such CODATA set was dated 1973 [2] , the second - 1986 [3] [4] , the third - 1998 [5] [6] , the fourth - 2002 [7] [8] , the fifth - 2006 [9] [10 ] , the sixth - 2010 [11] [12] and the seventh set - 2014 [13] .
Since 1998, in view of the tendency to create and publish information immediately on the Internet , the CODATA Working Group has changed its approach to publishing constant values, deciding to do this every four years.
By 2017, a special, extraordinary release of a set of values of fundamental constants was prepared, used for the final formulation of a new revision of the International System of Units (SI) . The release of the set of fundamental constants of 2018 was already based on the new version of SI, therefore, a significant change in the errors of a number of constants occurred in it.
