German Institute for Standardization


Deutsches Institut für Normung e.V. (DIN; in English, the German Institute for Standardization) is the German national organization for standardization and is that country’s ISO member body.

There are currently around thirty thousand DIN Standards, covering almost all fields of technology. One of the earliest, and surely the most well-known, is DIN 476, the standard that introduced the A-series paper sizes in 1922. This was later adopted as international standard ISO 216 in 1975.


DIN is a registered association (e.V.), founded in 1917, originally as Normenausschuss der deutschen Industrie (NADI, Standardisation Committee of German Industry).

In 1926 the NADI was renamed Deutscher Normenausschuss (DNA, German Standardisation Committee) in order to indicate that standardization now covered many fields, not just industrial products.

In 1975 the DNA was finally renamed DIN. Its headquarters is in Berlin. Since 1975 it has been recognized by the German government as the national standards body and represents German interests at international and European level.
