Vibration Analysis ISO CAT III
If you are ready to be the senior vibration analyst, with the capability of handling all the common fault conditions and leading the Category I and II analysts, then this is the course for you.
The Category III course is intended for people who are confident with spectrum analysis but who wish to push on and learn more about signal processing, time waveform and phase analysis, cross-channel testing, machine dynamics, and fault correction.
If you wish to truly advance in vibration analysis and be able to run a successful condition monitoring team, then you are ready for this course.
Course Information
Duration: 4.5 days
Plus 3-hour optional extra 3rd party certification exam through SPM Academy. 70% passing grade. Available at an additional cost.
Format: Classroom learning
Compliance: Follows ISO 18436-2 and 18436-3 and provides 3.5 Continuing Education Unit (CEU) credits.

Successful Condition Monitoring Program
- Alarms, reports, management, finances
Acceptance testing and ISO standards.
- Pre and post online course study material.
- Interactive assessments during the course.
- Student manual.
- Lunch and refreshments.
- Certificate of Attendance issued upon successful completion of the training course.
An SPM Academy 3rd party Certification exam is available at an additional cost.
- Certificate of Attendance issued upon successful completion of the training course.
- 3rd party Certification through SPM Academy available at an additional cost. ISO Category I certification exam, conducted online, on the last day of classroom training courses, or as an independently invigilated exam at a time of your choice. The exam follows ISO 18436-2 and 18436-3 and provides 3 Continuing Education Unit (CEU) credits.
Eligibility for SPM Academy certification:
- Complete a SPM Academy approved Vibration Analysis Category III training course
- Pass the SPM Academy Certification Centre CAT III certification exam
- Have at least 36 months of practical experience in vibration data collection or analysis.
Candidates who meet the certification requirements will be certified through the SPM Academy Certification Centre and be recognised as a Certified Category III Vibration Analyst. They will receive a digital certificate and a personalised digital badge.
