Absolute Vibration Levels
Once a specific machine problem is identified by its vibration signature, the next question should be "Is the problem bad enough to require maintenance?". There is no general agreement on how to do this but we will look at several approaches that have proven to be reasonably successful in practice:
ISO Standard 2372
MIL-STD-167-1 and MIL-STD-167-2
NAVSEA Technical Specification S9073-AX-SPN-010/MVA
Commercial Standards (DLI Machinery Vibration Severity Chart)
