DINNormen

DINNormen are the standards published by the Deutsches Institut für Normung (DIN), the German national standardization body. They provide specifications, criteria and test methods for products, services and processes to ensure safety, quality and interoperability within Germany and beyond.

DIN was founded in 1917 and operates as a registered association. It represents Germany in international and European standardization bodies such as ISO and CEN. DIN coordinates national standardization activities, develops new norms, and coordinates the adoption of international and European standards for the German market. The Beuth Verlag, a subsidiary of DIN, publishes and distributes DIN standards.

The standardization system includes differentiated designations. Some standards are published as DIN standards (e.g., DIN 1234). If a European standard is adopted in Germany, the designation may appear as DIN EN 1234 or as DIN EN ISO 1234, reflecting the combined national, European and international origins. DIN norms can be revised or withdrawn as technology and requirements evolve, following a formal development and voting process in technical committees.

Usage and legal status vary. DIN norms are not automatically legally binding unless referenced in laws, regulations or contracts. In practice, they are widely used in procurement, manufacturing, testing, certification and conformity assessment to ensure consistency and interoperability across industries.

DIN norms thus function as a key pillar of Germany’s technical infrastructure, linking national practice with regional and international standardization efforts.
