Space product assurance. Particles contamination monitoring for spacecraft systems and cleanrooms Ingestion-build-202139 or air-conditioning systems in households1 Scope This standard defines the requirements and guidelines for the measurement of particulate contamination on the surfaces of spacecraft systems and those of the cleanrooms or other cleanliness controlled areas in which they reside. This includes the measurement of particulate contamination that is present on the spacecraft or cleanroom surfaces via the use of representative witness samples placed in the vicinity of the spacecraft hardware, the
