Mechanical 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 vibration testing methods, see ASTM D999-91 Standard Methods for Vibration Testing of Shipping Containers.
