This part of ISO 20816 is applicable to land-based gas turbines, steam turbines and generators (whether coupled with gas and/or steam turbines) with power outputs greater than 40 MW, fluid-film bearings and rated speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min. The criteria provided in this part of ISO 20816 can be applied to the vibration of the main bearings of the gas turbine, steam turbine and generator (including synchronizing clutches). This part of ISO 20816 establishes provisions for evaluating the severity of the following in-situ, broad-band vibration: a) structural vibration of all main bearing housings or pedestals measured radial (i.e. transverse) to the shaft axis; b) structural vibration of thrust bearing housings measured in the axial direction; c) vibration of rotating shafts radial (i.e. transverse) to the shaft axis at, or close to, the main bearings. These are in terms of the following: - vibration under normal steady-state operating conditions; - vibration during other (non-steady-state) conditions when transient changes are taking place, including run up or run down, initial loading and load changes; - changes in vibration which can occur during normal steady-state operation. This part of ISO 20816 is not applicable to the following: 1. electromagnetic excited vibration with twice line frequency at the generator stator core and housing; 2. aero-derivative gas turbines (including gas turbines with dynamic properties similar to those of aero-derivatives);
