适用范围：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 shop process and usually does not require special environmental controls, packaging, handling or storage beyond accepted good practice. This part of ISO 14952 is applicable equally to ground support equipment, launch vehicles and spacecraft. NOTE The cleanliness level achieved by rough cleaning does not normally require verification beyond visual inspection. (Wipe test, waterbreak test, ultraviolet inspection, special lights and mirrors are considered aids to visual inspection.)
