MSFC-STD-3676A, MSFC TECHNICAL STANDARD: DEVELOPMENT OF VIBROACOUSTIC AND SHOCK DESIGN AND TEST CRITERIA (10-JAN-2013)

MSFC-STD-3676A, MSFC TECHNICAL STANDARD: DEVELOPMENT OF VIBROACOUSTIC AND SHOCK DESIGN AND TEST CRITERIA (10-JAN-2013)., This Standard describes the methodology used by the Marshall Space Flight Center to calculate random vibration, acoustic, and shock design and test criteria and subsequent design loads. In addition, the rationale for using these methods for launch vehicle components and payloads is described. Also included are guidelines and requirements for selection of appropriate criteria for qualification and acceptance testing and guidelines and requirements for their application in testing spaceflight hardware. The major requirements detailed in this standard are: • Section 6. Random vibration, acoustic and shock qualification test criteria shall be based on the P97.5/50 statistical basis. No margin is required above the maximum predicted environment. • Section 6. Acceptance testing shall be conducted 6 dB below the qualification test levels. • Section 6. Qualification test duration shall encompass flight environments as well as the fatigue induced by multiple acceptance tests. • Requirements to be implemented during vibroacoustic and shock qualification and acceptance testing are described in section 7. • Test tolerances are defined in section 7.
