Applicability

This NASA Technical Standard defines engineering practices for NASA programs and projects.

The criteria in this NASA Technical Standard are applicable to launch vehicle payloads and launch vehicle structures (including propellant tanks and solid rocket motor (SRM) cases). These criteria apply to flight hardware that is utilized for NASA missions. This NASA Technical Standard presents acceptable minimum factors of safety for use in analytical assessment and test verification of structural adequacy of the flight hardware. Designs are generally to be verified by both structural analyses and tests.

Criteria are specified for design and test of flight articles when the actual flight hardware is tested (protoflight), and when qualification tests are conducted on a separate (prototype) article. In general, no distinction is made between "human-rated" and "robotic" missions. Structures of human-rated flight systems may be subjected to additional verification and/or safety requirements (e.g., fracture control) that are consistent with the established risk levels for mission success and flight crew safety.

Specifically excluded from this NASA Technical Standard are requirements for design loads determination and fracture control. Also excluded are the design and test factors for engines, rotating hardware, solid propellant, insulation, ground support equipment, and facilities. This NASA Technical Standard also does not cover specific configuration factors such as fitting factors, buckling knockdown factors, and load uncertainty factors.

This NASA Technical Standard is approved for use by NASA Headquarters and NASA Centers and Facilities, and applicable technical requirements may be cited in contract, program, and other Agency documents. It may also apply to the Jet Propulsion Laboratory (a Federally Funded Research and Development Center [FFRDC]), other contractors, recipients of grants and cooperative agreements, and parties to other agreements only to the extent specified or referenced in applicable contracts, grants, or agreements.

References to "this Standard" refer to this NASA Technical Standard; references to external documents state the specific document information.

Verifiable requirement statements are designated by the acronym "FSR" (Factors of Safety Requirement), numbered, and indicated by the word "shall." This NASA Technical Standard contains 61 requirements. To facilitate requirements selection by NASA programs and projects, a Requirements Identification Matrix is provided in Appendix A.

Explanatory or guidance text is indicated in italics beginning in section 4. The terms "may" or "can" denote discretionary privilege or permission, "should" denotes a good practice and is recommended, but not required, "will" denotes expected outcome, and "are/is" denotes descriptive material or a statement of fact.
