This Standard sets out general guidelines for measuring and evaluating machinery vibration by means of measurements made directly on rotating shafts for the purpose of determining shaft vibration with regard to a) changes in vibrational behaviour; b) excessive kinetic load; c) the monitoring of radial clearances. It is applicable to measurements of both absolute and relative radial shaft vibration, but excludes torsional and axial shaft vibration. The procedures are applicable for both operational monitoring of machines and to acceptance testing on a test stand and after installation. Guidelines are also presented for setting operational limits.
