DIN

DIN, the German Institute for Standardization, is a registered association, founded in 1917. Its head office is in Berlin. Since 1975 it has been recognized by the German government as the national standards body and represents German interests on International and European level.

DIN offers a forum in which representatives from the manufacturing industries, consumer organizations, commerce, the trades, service industries, science, technical inspectorates, government, in short anyone with an interest in standardization, may meet in order to discuss and define their specific standardization requirements and to record the results as German Standards.
Standardization as undertaken by DIN is a service that aims to benefit the entire community.

DIN Standards promote rationalization, quality assurance, safety, and environmental protection as well as improving communication between industry, technology, science, government and the public domain.
In DIN, standards work is carried out by some 26,000 external experts serving as voluntary delegates in more than 4,000 committees. Draft standards are published for public comment, and all comments are reviewed before final publication of the standard. Published standards are reviewed for continuing relevance every five years, at least.
