This part of ISO 20816 provides guidelines for evaluating the bearing housing vibration measurements made at the bearings, bearing pedestals or bearing housings and also for shaft vibration measurements made on machine sets in hydraulic power generating and pump-storage plants when the machine is operating within its normal operating range. The normal operating ranges for each type of turbine covered by this part of ISO 20816 are defined in Annex A. These guidelines are presented both for running vibrations and for any changes in amplitude or phase which can occur in those vibration values. The numerical values given in Annex A are intended to serve as the basis for vibration evaluation and, if required, further investigation. It is recommended in this part of ISO 20816 that the condition of a machine is assessed by consideration of both the bearing housing vibration and shaft vibration. This part of ISO 20816 is applicable to machine sets in hydraulic power generating plants and in pump-storage plants with typical rotational speeds of 60 r/min to 1000 r/min fitted with shell or pad (shoe) type oil-lubricated bearings.
