DINWerte

DINWerte refers to numerical values defined within standards published by the Deutsches Institut für Normung (DIN). They function as reference quantities that aid design, production and testing by providing standardized measures, tolerances, material properties or performance criteria. DINWerte are typically embedded in DIN norms and are often harmonized with European (DIN EN) or international (ISO, IEC) standards, ensuring consistency across industries and markets. Examples include dimensions and tolerances for components, mechanical properties such as strength or hardness, or permissible ranges for temperature, pressure and other operating conditions. In practice, engineers use DINWerte when creating technical drawings, suppliers specify them in procurement documents, and inspectors verify compliance during quality control.

The process for establishing a DINWert usually starts with a need identified in an application. A DIN working group develops a standard proposal, which undergoes review before publication as a DIN normative document. In many cases, DIN-Werte appear within DIN EN standards that German national norms adopt to align with European rules. The use of DINWerte supports interoperability, safety and predictable performance, and it can facilitate international trade by providing recognized references. Values may be updated over time as technology advances, which requires organizations to track revisions and ensure current compliance.

Limitations include dependence on standardization cycles, regional applicability, and the possibility of multiple standards defining different values for similar properties. Consequently, DIN-Werte are best understood as a family of standardized numerical references rather than a single universal constant, embedded in the broader framework of DIN, ISO and EN standards.
