If you’re looking for a way to evaluate rotating equipment vibration, and you have no history or baseline, then you can use ISO 10816 (previously ISO 2372). The standard contains criteria for judging machine condition from casing velocity measured at a specified location at each bearing, expressed in inch/second rms or mm/second rms. Remember: rms not peak-to-peak.
This mini firewater pump however, does not need that standard. As it always vibrating at zero mm/s rms 😁
