scope:

The purpose of this NASA Technical Standard isto establish NASA structural design and test factors, as well as service lifefactors to be used for spaceflight hardware development and verification. Theprimary objective of this NASA Technical Standard is to define factors which ensuresafe and reliable structural designs. The secondary objective is to reducespace project costs and schedules by enhancing the commonality of use ofhardware designs among NASA flight projects, Centers, and their contractors.The criteria in this NASA Technical Standard are to be considered as minimumacceptable values unless adequate engineering risk assessment is provided thatjustifies the use of lower values.
