Deutsches Institut für Normung (DIN)

DIN itself does not develop standards. Rather, the institute fulfills a mandate from the Federal Republic of Germany. Its tasks are to bring together all stakeholders relevant to a topic and to represent German interests in European and international standardization.

Accordingly, a standard is a technical description that is accessible to everyone and is based on agreed results of science, practice and technology. A standard is approved by a recognized organization:

  • at regional or national level, by the German Institute for Standardization (DIN)
  • at European level by the European Committee for Standardization (CEN), which is responsible for European Standards (EN)
  • at international level, for example, by the International Organization for Standardization (ISO) or the International Electrotechnical Commission (IEC)
