Random Vibration Test Checklist
A checklist for planning and executing a random vibration qualification test.
Checklist
- Test PSD specification verified — breakpoints, Grms, duration, axes
- Fixture qualified — first fixture mode above test range with margin
- Control accelerometer at fixture-article interface
- Response accelerometers at critical locations (from analysis)
- Accelerometer mass loading checked for lightweight articles
- Signal quality verified — noise floor, grounding, cables
- Notching analysis prepared if needed (interface loads or response limits)
- Acceptance criteria defined — functional and structural
- Post-test inspection plan prepared — visual, functional, NDT
