Description of BS ISO 7919-3:2009+A1:2017 2018This part of ISOÂ 7919 gives guidelines for applying evaluation criteria of shaft vibration under normal operating conditions, measured at or close to the bearings of coupled industrial machines. These guidelines are presented in terms of both steady running vibration and any amplitude changes which can occur in these steady values. The numerical values specified are not intended to serve as the only basis for vibration evaluation since, in general, the vibratory condition of a machine is assessed by consideration of both the shaft vibration and the associated structural vibration. This part of ISOÂ 7919 applies to coupled industrial machines with fluid-film bearings, having maximum continuous rated speeds in the range 1Â 000Â r/min to 30Â 000Â r/min and not being limited by size and power (with certain restrictions), comprising
The information relating to pumps provided in this part of ISO 7919 complements that given in ISO 10816‑7 . In particular, the conditions for in-situ operation, performing acceptance tests and the influence of bearing clearance given in ISO 10816‑7 shall be taken into account when evaluating the shaft vibration of pumps. The following are excluded from this part of ISO 7919 :
