DIN and mini-DIN connectors, as well as DIN rails are several examples of older DIN standards that are today used around the world. However, there are actually several thousand DIN standards, covering any conceivable area of science and technology. One of the oldest, and surely the most popular, is DIN 476, the standard that introduced the A4, etc. paper sizes in 1922, which 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 the German industry). In 1926 the NADI was renamed to Deutscher Normenausschuss (DNA, German standardisation committee), in 1975 the DNA was finally renamed to 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.
The acronym DIN is often wrongly expanded as Deutsche Industrienorm (German industry standard). This is largely due to the historic origin of the DIN as the NADI. The NADI indeed published their standards as DI-Norm (Deutsche Industrienorm, German industry standard). E.g. the first published standard in 1917 was 'DI-Norm 1' (about taper pins). Many people still wrongly associate DIN as an abbreviation for the old DI-Norm naming of standards.
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 German edition of European standards. DIN ETS # is used for standards prepared by European Telecommunications Standards Institute.
- DIN ISO # is used for German edition of ISO standards. DIN EN ISO # is used if the standard has also been adopted as a European standard.
