ISO 18436 Category II
Intermediate Vibration Analyst Training & Certification
The ISO Category II Vibration Analyst “Intermediate” course is intended for personnel who have at least twelve months of vibration analysis experience and a basic understanding of vibration theory and terminology. The course provides an in-depth study of machinery faults and their associated spectrum, time waveform and phase characteristics. Category II certification requires that you have demonstrated 18 months experience in vibration analysis, completed the Category II course and successfully pass the Category II vibration analyst examination. However Category I is not a prerequisite to become certified as a Category II vibration analysts.
Course Description
Duration: 4.5 days training & 3-hour Exam; 70% passing grade
Compliance: ISO 18436 Category II – Vibration Analyst, ASNT SNT-TC1A Recommended Practice
Certification Prerequisite: Prior experience is not required for attending the training course but 18 months of experience is required for certification.
Outcome: You will come away from this course with a very good understanding of vibration analysis fundamentals, and you will be competent in quality data acquisition and diagnosing common machine faults.

Category II Topics covered:
- Review of maintenance practices
- Review of condition monitoring technologies
- Principles of vibration; Review of basics, waveform, spectrum (FFT), phase and orbits
- Understanding signals: modulation, beating, sum/difference
- Data acquisition
- Signal processing
- Vibration spectrum analysis
- An introduction to time waveform analysis
- An introduction to orbit analysis
- Phase analysis: bubble diagrams and ODS
- Enveloping (demodulation), shock pulse, spike energy, PeakVue™
- Fault analysis
- Equipment testing and diagnostics including impact testing (bump tests) and phase analysis
- Corrective action
- Running a successful condition monitoring program
- Acceptance testing
- Review of ISO standards
You will come away from the course with a solid understanding of:
- How a well-designed program and a reliability centred maintenance approach improve the OEE and therefore the bottom line
- The condition monitoring technologies: acoustic emission, infrared analysis (thermography), oil analysis, wear particle analysis, & motor testing via supplementary training
- How machines work; via supplementary self-study using the “Equipment Knowledge” section
- How to select the correct measurement location and axis, and collect good, repeatable measurements
- What the Fmax, resolution, averaging and other analyzer settings mean, and how to select the optimum settings for a wide variety of machine types
- How to analyze vibration spectra, time waveforms, envelope (demodulation), and phase measurements
- How to diagnose: unbalance, eccentricity, misalignment, bent shaft, cocked bearing, looseness, rolling element bearings faults, journal bearing faults, gearbox faults, resonance, and other conditions
- How to set alarm limits manually and with statistics
- How to balance and align a machine, and correct a resonance condition
