Deutsches Institut für Normung: The German Institute for Standardization e. V. (DIN for short) is the most important national standards organization in the Federal Republic of Germany.
This organization was founded on 22 December 1917 under the name “Standards Committee of German Industry”. In 1926, it was renamed “Deutscher Normenausschuss” (German Standards Committee) for the first time, to express the fact that its field of activity was no longer limited to industry. The current name was chosen in 1975 in connection with the standards agreement concluded between the Organisation and the Federal Republic of Germany. The standards drawn up under the direction of the working committees of this standardization organization are referred to as DIN standards.
