ISO 14952-4:2003 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.
ISO 14952-4:2003 is applicable equally to ground support equipment, launch vehicles and spacecraft.
