BS ISO 10816-4:2009+A1:2017 Historical

BS ISO 10816-4:2009+A1:2017 establishes provisions for evaluating the severity of in-situ, broad-band vibration measured radial (i.e. transverse) to the shaft axis on all main bearing housings or pedestals and in the axial direction on thrust bearings. These are in terms of:

• 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 10816 is applicable to heavy-duty gas turbine sets used in electrical and mechanical drive applications, with fluid-film bearings, outputs greater than 3 MW and an operating speed range under load between 3 000 r/min and 30 000 r/min. This includes gas turbines coupled to other rotating machinery either directly or through a gearbox. In some cases, this part of ISO 10816 is not applicable to the evaluation of the vibration of the coupled equipment (see the list of exclusions in this clause).
