About the Training

Category III Vibration Analysts are qualified to establish, direct, and or perform programs for condition monitoring and diagnostics of machines including spectral, waveform, and orbit analysis. Category III certified Vibration Analysts shall be qualified to perform minor corrective actions involving operating deflection shapes, single-plane balancing, and diagnostic testing.

Minimum Experience Required: 36 Months

Minimum Training Hours: 90 hours (38 hours + VI Category II)

Recommended Vibration Training meeting requirement: Basic Machinery Vibration - CAT III, Balancing of Rotating Machinery - CAT III

The online training class will commence on soon, and will run for 18 sessions. The class will be conducted every Monday to Saturday, from 7:30 PM to 9:30 PM, and will last for 2 hours per day. If necessary, the number of sessions may be extended.

Examination Details

The examination is conducted in a physical setting at our testing center located in Bhubaneswar, Odisha, India.

The duration of the examination is 3 hours, during which candidates will be required to answer multiple-choice questions that test their understanding of the course material. The questions will be presented in a format where candidates need to select the best answer out of four choices.

Candidates who successfully complete the examination will receive a certification. This certification is globally recognized and serves as a testament to the candidate's knowledge and expertise in the field of vibration analysis.
