rostgraden
Rostgraden is a term used in materials science and maintenance to describe the extent of rust on a metal surface. It is employed to assess corrosion effects, guide maintenance planning, and help determine necessary protective actions. In practice, rostgraden appears in Swedish-language technical literature and by engineers working with structures, pipelines, and machinery. There is no single universal standard for rostgraden; typical practice describes rust levels in categories such as none, trace, light, moderate, and severe, with some schemes distinguishing features like rust color, flaking, pitting, or corrosion depth.
Assessment methods include visual inspection aided by photography or standardized rust color charts, as well as
Applications of rostgraden include maintenance scheduling, coating selection, material replacement decisions, and quality control during manufacturing
