Vibration specifications
Continuous vibration can cause a slow degradation of mechanical parts and, when severe, can cause
data errors in disk drives. Mechanical connections such as printed circuit assembly (PCA) conductors,
cable connectors, and processor backplane wiring can also be affected by vibrations. Vibration
specifications apply to all three axes. For specification tests, see ASTM D999-91 Standard Methods
for Vibration Testing of Shipping Containers.
