Sets out the procedure for evaluating the vibration severity of rotating machines with powers less than 300 kW and speeds from 10 r/s to 200 r/s. These machines may be coupled rigidly or flexibly or they may be connected through gears. It does not apply to prime movers or driven equipment in which the major working components have a reciprocating motion.
