Performance Standards – Overview

Ensuring that complete and proper measurements are compiled during each inspection, and confirming that the time between readings meets our standard, is key to our certified commitment to provide the highest quality of service at a reasonable price.

These exacting standards are used by Vibtech:

  • All data collectors shall be calibrated annually. Calibration certificates are to be provided to customers upon request.
  • All analysts shall be certified by outside institutions before they may work unsupervised.
  • The following minimum vibration data shall be recorded:
    • Velocity overall readings and spectrum with 800 lines of resolution shall be recorded on all points with a minimum of 4 averages.
    • Spike Energy overall readings and spectrum with 800 lines of resolution shall be recorded on all points.
    • Acceleration spectra with 800 lines of resolution shall be recorded on all horizontal points with a minimum of 4 averages.
    • A low frequency velocity spectrum with a maximum frequency of 12,000 CPM with a minimum of 4 averages shall be taken in the horizontal positions on all AC motors. (This equates to a minimum of 26 spectra & 20 overall readings for a standard 4 bearing unit, ie. fan & motor)
    • Predictive Maintenance Programs must not exceed 3 months between readings.
    • All reports shall be mailed to the customer no later than 10 business days following completion of the work with the exception of Predictive Maintenance Start-ups which may require up to 15 business days.
