Course Description
The Vibration Analysis Category IV course represents the pinnacle of the vibration analysis field — BII Research calls Category IV analysts the "vibration superheroes". This challenging course prepares the most advanced analysts to solve the toughest machinery problems and to lead diagnosis at the highest technical level.
Training and accredited certification follow ISO 18436-2 and ISO/IEC 17024 via the certifying body. Category IV represents expert mastery of vibration diagnostics, corrective action, and advanced dynamics.
What you will achieve
By the end of this training course, participants will be able to:
- Diagnose the most complex and unusual machinery faults
- Apply advanced dynamics: rotordynamics, modal analysis, and ODS
- Perform structural and resonance analysis
- Lead root cause analysis of chronic vibration problems
- Specify and verify corrective actions for difficult cases
- Mentor and guide lower-category analysts
- Prepare for the ISO 18436-2 Category IV certification exam
How the course is delivered
The course applies BII Research's most advanced Crystal Clear content — high-fidelity 3D animations and simulations of complex dynamics — combined with expert instruction and demanding case studies drawn from real chronic problems.
Participants access the iLearnVibration system and Learning Zone, with expert-level reference material to support advanced diagnostic work.
