HISTORY

Founded in 1917 as the _Normenausschuß der deutschen Industrie_ (NADI, "Standardisation Committee of German Industry"), the NADI was renamed _Deutscher Normenausschuß_ (DNA, "German Standardisation Committee") in 1926 to reflect that the organization now dealt with standardization issues in many fields; viz., not just for industrial products. In 1975 it was renamed again to _Deutsches Institut für Normung_, or 'DIN' and is recognized by the German government as the official national-standards body, representing German interests at the international and European levels.

The acronym , 'DIN' is often incorrectly expanded as _Deutsche Industrienorm_ ("German Industry Standard"). This is largely due to the historic origin of the DIN as "NADI". The NADI indeed published their standards as _DI-Norm_ (_Deutsche Industrienorm_). For example, the first published standard was 'DI-Norm 1' (about tapered pins ) in 1918. Many people still mistakenly associate DIN with the old _DI-Norm_ naming convention.

One of the earliest, and probably the best known, is DIN 476 — the standard that introduced the A-series paper sizes in 1922 — adopted in 1975 as International Standard ISO 216 . Common examples in modern technology include DIN and mini-DIN connectors for electronics, and the DIN rail .

DIN STANDARD DESIGNATION

The designation of a DIN standard shows its origin (# denotes a number):

* _DIN #_ is used for German standards with primarily domestic significance or designed as a first step toward international status. _E DIN #_ is a draft standard and _DIN V #_ is a preliminary standard. * _DIN EN #_ is used for the German edition of European standards. * _DIN ISO #_ is used for the German edition of ISO standards. * _DIN EN ISO #_ is used if the standard has also been adopted as a European standard.
