DIN standard

A DIN standard is defined as being a document drawn up with consensus and accepted by the DIN Deutsches Institut für Normung (German standards institute). It defines rules, guidelines or characteristics for activities or results for general and recurring applications, whereby it aims to achieve an optimum degree of order.

DIN standards should be based on the assured results of science, engineering and experience and serve the general public. They are drawn up in the process of standardisation.

DIN standards can be national standards, European standards or international standards. The name of a DIN standard indicates its origin and scope.
They save time-consuming, complicated specifications of individual components or equipment if it is stated on which DIN standard the production was based.

The standard number indicates the origin of a standard:

• DIN: (e.g. DIN 33430) DIN standard which has solely or mainly (German) national significance or is published as a preliminary stage of an international document.
• DIN EN: (e.g. DIN EN 14719) German adoption of a European standard (EN). European standards, if they are adopted, must be adopted unchanged by the members of CEN and CENELEC.
• EN ISO: (e.g. DIN EN ISO 9921) German adoption of a standard produced under the overall control of ISO or CEN, which has then been published by both organizations.
• EN ISO/IEC: (e.g. DIN EN ISO/IEC 7810) German standard based on a European standard, which in turn is based on an international ISO/IEC standard.
• EN ISP: (e.g. DIN EN ISP 10608-6) German standard based on a European standard, which in turn is based on an international standardized profile.
• DIN ISO: (e.g. DIN ISO 10002) Unchanged German adoption of an ISO standard.
• DIN IEC: (e.g. DIN IEC 60912) Unchanged German adoption of an IEC standard.
• DIN CEN/TS and DIN CLC/TS: (e.g. DIN CLC/TS 50459-1) Unchanged German adoption of a European technical specification.
• DIN CWA: (e.g. DIN CWA 14248) Unchanged German adoption of a CEN or CENELEC Workshop Agreement (specifications/technical rules).
• DIN VDE: Electrical engineering, electronics and information technology topics are jointly dealt with by DIN and VDE through the DKE. Please refer to the list of DIN-VDE standards.
