0ZRauheit
0ZRauheit is a term encountered in technical discussions that relate to ultra-low surface roughness in precision engineering. In practice, its exact meaning is not standardized and can vary between industries, suppliers, and documentation. The phrase is often used in German-language contexts to denote a target or designation for extremely smooth surface finishes, rather than a universally defined metric.
Interpreting 0ZRauheit typically involves reference to surface roughness metrics such as Ra, Rq, or Rz measured
Standards related to roughness rely on established international guidelines such as ISO 4287 and ISO 2527
