Mechanical vibration. Measurement and evaluation of machine vibration - Gas turbines in excess of 3 MW, with fluid-film bearings1 Scope This document is applicable to land based gas turbines with fluid film bearings and power outputs greater than 3 MW and an operating speed under load between 3 000 r min and 30 000 r min. In some cases (see the list of exclusions below), this includes other rotating machinery coupled either directly or through a gearbox. The evaluation criteria provided in this document are applicable to the vibration of the main input and output bearings of
