scope:

The term vibroacoustics is defined as an environment induced by high-intensity acoustic noise associated with various segments of the flight profile. It manifests itself throughout the payload in the form of transmitted acoustic excitation and as structure-borne random vibration. Therefore, the standard is to specifically address the acoustic and random vibration environments and test levels.

Purpose. The primary objective of this standard is to establish a uniform usage of test factors in the vibroacoustic verification process for spaceflight payload hardware. The standard provides test factors for verification of payload hardware for prototype, protoflight, and flight acceptance programs. In addition, minimum workmanship test levels are included. With the exception of minimum workmanship test levels, the test levels are given in relation to the "maximum expected flight level" (MEFL). Although the major emphasis of the standard is on test levels, the standard also covers the subjects of test duration, test control tolerances, data analysis, test tailoring, payload fill effects, and analysis methods.
