Vibration Analysis Cat III - Overview

Vibration Analysis Training: ISO Category III + ASNT Level III

The course exceeds the ISO 18436-2 Category III standard and meets the ASNT Level III Recommended Practice (for vibration analysis). The certification exam can be taken after the course.  (Note: The ASNT Level III exam can only be administered by the ASNT.)



5 days including optional ISO 18436-2 certification exam on the fifth day

As a Category III vibration analyst you are expected to be able to diagnose all of the common faults conditions with rolling element bearing machines; have a good understanding of fault conditions associated with sleeve bearing machines; utilise time waveforms, phase readings and enveloping/PeakVue etc. readings to diagnose faults; and understand all condition monitoring technologies, how and when to apply them, and how to combine technologies to get the best results.

You must also understand machine dynamics (natural frequencies, resonance, etc.); how to perform resonance testing; and how to correct resonance problems.  You must also understand balancing, alignment, and isolation.  You are also, therefore, required to understand all of the single and cross-channel measurement capabilities of your analyser.

And finally, you are also expected to be able to set up the program, run a successful program, and mentor the junior analysts.


You will come away from the course with a solid understanding of:

  1. How a well designed program, and the reliability centered maintenance approach (with precision balancing, alignment, lubrication and resonance control), will improve the OEE and therefore the bottom line.

  2. The condition monitoring technologies: acoustic emission, infrared analysis (thermography), oil analysis, wear particle analysis, motor testing – via supplementary training

  3. How to select the correct measurement location and axis, and collect good, repeatable measurements

  4. What the Fmax, resolution, averaging and other single-channel and cross-channel analyser settings mean, and how to select the optimum settings for a wide variety of machine types

  5. How to analyse vibration spectra, time waveforms, envelope (demodulation), and phase measurements

  6. How to diagnose a wide range of fault conditions: unbalance, eccentricity, misalignment, bent shaft, cocked bearing, looseness, rolling element bearings faults, journal bearing faults, gearbox faults, resonance, and other conditions

  7. How mass, stiffness and damping affects the natural frequency of a structure

  8. How to use phase readings, bump tests, impact tests, negative averaging, peakhold averaging, transient (run up and coast down), ODS, and modal analysis to determine natural frequencies and visualize machine movement

  9. How to set alarm limits manually and with statistics

  10. How to balance and align a machine, correct a resonance conditions, and employ isolation.

Who should attend?

If you are Category II (or Level II) certified and are ready to take your career and responsibilities to the next step, and you wish to truly master vibration analysis, diagnosis and correction, then this course is ideal for you.

You should have over 30 months of experience and a good understanding of fault diagnosis and spectrum analysis.   (Note that you require 36 months experience to be certified.)

The RMS / Mobius Institute course and certification program follows the ISO 18436-2:2003 standard and the ASNT Recommended Practice SNT-TC-1A.

What is unique about this course?

RMS / Mobius make it unique.  We use 3D animations, Flash simulations, and numerous software simulators that completely demystify vibration analysis.  While vibration training courses have traditionally been very theoretical, difficult to understand, (and boring), you will be captivated by the Mobius Training methods, and you will enjoy our practical approach.  You will take away skills that you can immediately apply to your job, and you will truly understand what you are doing.  When senior vibration analysts attend our classes they often say “if only I could have learned this way when I got started” – well, now you can!
