Vibration Testing (Vibration Criterion and ISO) for Sensitive and Laboratory Equipment

Vibration Testing for Laboratory Equipment

Many forms of precision equipment, such as equipment used in the semiconductor manufacturing, nanotechnology, electron beams, and optics, require low levels of ground vibration for proper use. Vibrations from footfall, vehicle pass-by on exterior roads, construction, aircraft, local railroads, facilities, wind, or even air pressure can all induce vibrations in a building’s structure. In these precision applications the smallest ground-borne vibrations may cause errors and be costly.

Typical measurements are compared to tolerance limits defined by standards including BBN curves, IEST VC curves, and ASHRAE curves. These curves have are a series of curves that range in strictness based on the equipment type from surgical suites on the low end to nanotechnology applications on the high end.

The comparison measurements are often done in frequency spectra based third octave bands of velocity data. VibeCloud’s team of analysts acquire high-accuracy velocity data or acceleration data, convert acceleration to velocity, and report the frequency data in proportional band (1/3 octave) displays.
