ISO 10816 Vibration Severity Standards
ISO 2372 (10816) Standards provide guidance for evaluating vibration severity in machines operating in the 10 to 200Hz (600 to 12,000 RPM) frequency range. Examples of these types of machines are small, direct-coupled, electric motors and pumps, production motors, medium motors, generators, steam and gas turbines, turbo-compressors, turbo-pumps and fans.

INTRODUCTION TO VIBRATION TECHNOLOGY
vibration and the longer the machine will perform before failure. It''s really that simple. Low levels of vibration indicate low vibratory forces , resulting in improved machine life. Of course, there are other reasons to strive for low levels of machinery vibration besides increasing the time between failures.

Vibration
A typical vibration measurement system includes a device to sense the vibration (accelerometer), and an instrument to measure the level of vibration. This equipment also has settings for measuring frequency, a frequency-weighting network, and a display such as a meter, printer or recorder. The accelerometer produces an electrical signal.
