Reliability Competency

ISO Vibration Course and Certification Category II


As a Category II analyst you are expected to know how to test machines correctly, how to diagnose faults accurately (and perform additional tests to verify your diagnosis), how to set vibration alarm limits, and how to correct certain types of faults. Now it is time to understand what those analyzer setting mean so that you can take the best measurements. Now it is time to understand why the vibration patterns change the way they do – and how to use time waveform analysis and phase analysis to verify the fault condition.


If you have been performing vibration analysis for more than six months, and feel that you have a good understanding of the fundamentals, then you are ready to step up to the Category II course. (Note that you require 18 months experience to be certified.) Anyone who wants to be confident and capable of diagnosing a wide range of fault conditions, correct certain condition, and taking accurate measurements needs to take this course. Many plant sites require contractors to be certified, and many employers require employees to be certified. The Mobius Institute course and certification program follows the ISO 18436-2 standard and the ASNT Recommended Practice SNT-TC-1A.
