· Please note that the ISO 10816-3 chart is for “advised” levels of vibration quality. Some common sense must be used as well. As an example, a machine tool would need to operate at a lower level of vibration, to maintain machining finish quality. A hammer mill might operate at a higher vibration level while in use.
