Sets out the procedure for evaluating vibration performance of large machines with rotating masses and a power of more than 300 kW and speeds from 10 r/s to 200 r/s. These machines can either be coupled rigidly or flexibly or can be connected through gears. It is concerned only with the severity of the mechanical vibration of individual machine systems and not with the sound energy radiated from individual vibrating parts.

This standard sets out the procedure forevaluating the vibration performance of large prime movers and other large machines with rotating masses only, a power of more than 300 kW, and speeds from 10 r/s to 200 r/s. Examples of these types of machines are electric motors and generators, steam and gas turbines, turbo-compressors, turbo-pumps and fans. Some of these machines can be coupled rigidly or flexibly, or they can be connected through gears. The axis of the rotating shaft may be horizontal, vertical or inclined at any angle between these directions.
