Normvariante

Normvariante is a term used chiefly in German-language technical and regulatory contexts to denote a variant that conforms to a normative standard. The word combines Norm (standard, rule) and Variante (variant). In practice, a normvariante is a version of a product, component, or procedure designed to meet specific standards published by recognized bodies such as DIN, ISO, EN, or IEC. It is distinguished from variants that do not adhere to those standards, or from custom or non-conforming variants.

In engineering and manufacturing, normvariante ensures interchangeability and compatibility with other parts and systems. Examples include a fastener made to DIN or ISO specifications, an electrical connector with defined pinout and insulation ratings, or software that implements a standard interface. Documentation typically includes references to the normative standard, tolerances, materials, and performance criteria. Verification often involves conformity testing, inspection, and certification by testing laboratories.

The concept supports quality control, procurement, and safety by reducing variability and ensuring that components from different suppliers fit and function together. However, the term is primarily used in German-speaking settings; in other languages, terms like standard-compliant variant or conforming variant may be used.
