ISO 18436 Category IV – Expert Vibration Analyst

Vibration Analysts certified to Category IV shall have all the knowledge and capabilities of the lower level categories. They will have a broad technical knowledge and experience of a range of machines, and an in-depth knowledge of a selection of them. They are able to perform signal analysis, including frequency and time domain processing, and they can determine natural frequencies, mode shapes and damping of systems, operating deflection shapes of machines and recommend means for correction.

Category IV analysts can apply vibration theory and techniques (including measurement and interpretation of multi-channel spectral results), basic principles of rotor-bearing dynamics and advanced two-plane balancing.

In order to be certified you must:

• Complete a MIBoC approved training course
• Achieve 70% or higher on the certification exam
• Have sixty (60) months of practical vibration analysis work experience, verified by an independent person
• Have previously been VCAT-III certified by a MIBoC approved certification body.

Certification is valid for 5 years.

If you do not have the experience, you will still receive a certificate, but you will not be officially certified. When you pass the 60-month milestone, you are eligible to be upgraded to full certification.
