ISO Category III (Analysis II)



  • At least 1 to 2 years vibration spectrum analysis experience.
  • General familiarity with using a calculator and with a computer is required.
  • Good math skills and simple Algebra, primarily solving for one unknown, is a must.
  • Some fundamental Trigonometry background will also prove helpful.
  • If ISO Vibration Certification is desired at Category III, a student must be ISO Category II certified.

Recommended For:

  • Recommended Full-Time PdM Vibration Experience = 6 to 12 Months


This three-day seminar builds from ANALYSIS I and is primarily intended to enhance the vibration expertise of analysts having approximately one-half to one year experience.


The curriculum allows the analysts to significantly improve the effectiveness of their condition monitoring programs.


Techniques are provided on how to detect each of 40 machine problems shown in our world renown Illustrated Vibration Diagnostics Chart, along with numerous real-world case histories demonstrating how these problems have been detected and corrected (250 page Case History Section).


Diagnoses of more complex machine problems are taught including gear, rotor rub, journal bearing, electrical, hydraulic/aerodynamic, beat vibration, resonance and tracking of rolling element bearing “failure scenarios".


Refinement of Overall and Spectral Band Alarms using proven statistical techniques and real-world examples is explained. Important FFT Processing Techniques are covered including: window selection, averaging types, overlap processing, dynamic range, and the significance of bandwidth.


Introductory information is provided on how to: (1) specify meaningful Narrowband envelope alarms, (2) perform natural frequency tests; (3) analyze time waveforms; (4) use synchronous time averaging; (5) interpret amplitude demodulated spectra and waveforms; and (6) specify proper vibration isolation and damping treatments.
