surface cleanliness requirements, requirements for O2, Fuel, and pneumatic components
This specification establishes surface cleanliness requirements for oxygen, fuel, and pneumatic components used in space vehicle fluid systems and associated ground support equipment (GSE) and test facilities. This specification is not intended to specify cleanliness requirements for composite surfaces used in cryogenic service, but it may be used to specify internal cleanliness requirements for metal-lined composite over-wrapped pressure vessels (COPVs). General cleaning requirements, verification procedures, drying and packaging requirements are provided. Each user shall require sub-tier documents to address processing, system cleanliness, solvent selection, cleanliness verification, and maintenance. An engineering assessment shall be necessary to establish requirements for each system.
