Deutsches Institut für Normung

Deutsches Institut für Normung e.V. (DIN; in English, the German Institute for Standardisation) is the German national organization for standardization and is the German ISO member body. DIN is a German Registered Association (e.V.) headquartered in Berlin. There are currently around thirty thousand DIN Standards, covering nearly every field of technology.

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 recognised 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 SPEC 3105, published in 2020, is "the first German standard to be published under an open license (CC-BY-SA 4.0) [...] to implement an open standardisation process".[1]

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.

Examples of DIN standards

Access to standards

For three EN standards, which are available as DIN-EN standards for a fee from DIN Media GmbH (formerly Beuth Verlag),[2] [3] [4] the European Court of Justice (ECJ) decided on March 5, 2024 that these must be made available free of charge because these standards are part of European Union law.
