Cat 2 Vibration Analysis Certification Training / HOUSTON, TX

April 15 - April 19


The Category 2 Vibration Analysis Course meets or exceeds requirements of ISO 18436-2. It is intended for students who will be involved in the day to day testing and analysis of machinery vibration data.

The course duration is four days with an optional 3 hour certification exam (100 questions / 70% to pass) on day 5.

Overview of Course Contents

  • Maintenance Practices
  • Condition Monitoring Technologies
  • Principles of Vibration
  • Data Acquisition
  • Signal Processing
  • Fault Analysis
  • Corrective Action
  • Equipment Knowledge
  • Acceptance Testing
  • Equipment testing and Diagnostics
  • ISO Reference Standards
  • Reporting and Documentation
  • Fault Severity Determination
  • Running a Successful Program

Upon completion of this course, students will have a good grasp of vibration analysis concepts and they will be able to set up machine tests and routes, analyze data, use relevant standards and create reports.
