scope:

This specification applies to all discrete components, subsystems, and totally assembled systems which together comprise either "contamination sensitive hardware" or hardware that has been determined to be a potential contamination source for the "contamination sensitive hardware". Of particular critically are those discrete components or subsystems which have either a direct line of sight to, or are located in the same enclosure as the "contamination sensitive element". Included is all ground support equipment (GSE) to which the flight hardware is exposed during ground operations, where the environmental conditions during this exposure could cause the GSE to outgas molecular contaminants. An example of such GSE is hardware used inside vacuum chambers during thermal vacuum testing.
