Space systems. Surface cleanliness of fluid systems - Rough-cleaning processes Ingestion-build-109673 EN 71-1 is the first1 Scope This part of ISO 14952 provides requirements related to rough cleaning processes used to prepare parts and components for precision cleaning. It identifies precleaning processes that can be used for ground support equipment, launch vehicles and spacecraft. Rough cleaning removes contaminants such as weld scale, heat treat scale, corrosion, oxide films, oils, grease, shop soil, fuel and carbon deposits. Rough cleaning is considered a normal
