VIBRATION SEVERITY CHAT & TOLERANCE GUIDE
VIBRATION CRITERION AS PER VDI 2058, ISO 2372, BS 4675 STANDARD
Vibration Severity Criteria for evaluating condition for machines running at the frequency of 10 Hz to 1000Hz. Example of these types of Machine are small, direct-couples Electric Motors and Pumps, Production Motors, Medium Motors, Generators, Steam and Gas Turbines, Turbo Compressors, Turbo Plums and Fans. some of these machines can be coupled rigidly or flexibly or connected though gear. The axis of Rotating shaft may be horizontal, vertical or inclined at any angle

The below given chart helps us to evaluate condition of over all vibration level as per VDI 2056, iso 2372, BS 4675 STANDARDS depending upon the power rating of the Equipment. Based on the same, assessment of the Equipment can be done and its condition can be classified and know

vibration severity ranges

A Typicale example is the standard VDI 2056. The vibration amplitude of the machine during smooth operation can be taken as Good" classfication. The vibration criteria suggests that successive vibration increase of about 2.5 will be more the vibration condition from Good" to "Allowable" to "Just Allowable" to "Not permissible"
