This is a core activity in the area in which IUPAC is recognized as the world authority on chemical nomenclature, terminology, standardized methods for measurements, atomic weights, etc.

Since January 2002, this Committee supersedes the Interdivisional Committee on Nomenclature and Symbols (IDCNS)
