Specification of the rotating component in space
science experiments - Part 10: Storage and
reinspection
1 Scope
This Part of GB/T 28878 specifies the storage conditions and reinspection methods of rotating component in space science experiments under specified conditions, as well as data analysis and evaluation after storage. Among them, if there are special requirements for the environmental conditions of storage and reinspection in the contract or technical requirements, it shall be implemented in accordance with the contract or technical requirements.
This Part applies to the storage and reinspection of rotating component in space science experiments at the component level and the complete-machine level. The storage and reinspection of rotating component of other payloads and spacecraft platforms in the corresponding state can refer to it for use. 2 Normative references
