International Classification for Standards (ICS)

Last Updated 10/17/2023

An international classification system developed and maintained by the International Organization for Standardization.  ICS are used to catalog and classify standards,  often for use in databases and libraries.  ICS currently includes 40 fields. Standards are organized according to:

  • sectors of the economy (e.g., agriculture, mining construction, packaging industry)
  • technologies (e.g., telecommunications, food processing)
  • activities (e.g., environmental protection , safety assurance and protection of public health)
  • fields of science (e.g., mathematics, astronomy)

The latest editions of the ICS are downloadable free of charge from the ISO website. Anyone may propose revisions or additions to the ICS.
