Use & Relationship
The Vibration and High Cycle Fatigue Test Report contains the data results of measurement surveys, defining the vibration source characteristics and existing environment of the final air vehicle configuration. It will also include the system level test results that are used to update the vibration and fatigue analysis assumptions and service life predictions. The principal use of this test report is to verify and update the vibration and fatigue analyses.
a. This Data Item Description (DID) is applicable to any contract for which an air vehicle is under development, a modification is made, or an Environmental Criteria Document (ECD) is required.
b. This DID contains the format, content, and intended use information for the data deliverable resulting from the work task described in section 5 of MIL-STD-1530, Aircraft Structural Integrity Program (ASIP) (copies of this document are available online at https://quicksearch.dla.mil).
