Balancing of Rotating Machinery - CAT III & CAT IV
This course covers single plane balancing in detail and introduces dual plane balancing for rotating machines. It includes both field balancing and shop balancing techniques. Topics such as pre-balance checks, influence coefficients, static-couple and course workshops are included. This course is partial preparation for the ISO 18436-2:2014 Vibration Analyst Category III & Category IV Certification Exams and the Balancing Specialist Exam by the Vibration Institute.
Balancing of Rotating Machinery
This course covers single and basic two-plane balancing techniques. It includes both field balancing and shop (balancing machine) balancing. Topics included are pre-balance checks, influence coefficients, balance quality and tolerances, residual unbalance testing and case histories. It is partial preparation for the Vibration Analyst Category III and IV, and Balancing Specialist Certification Exams.

Training Examination Review
The cancellation of and transfer to a training course within the same calendar year will be honored, provided that written notification is received by the Institute office via e-mail or mail no later than ten (10) business days before the first day of the scheduled course. If registration for a training course is cancelled without transfer to another course within the same calendar year, a $250 cancellation fee will be assessed. A $500 administrative fee will be charged for cancellations received less than ten (10) days from the start date of the registered training course. Additional cancellation fees will be applied for exam cancellations. Absentees for the course will not receive a refund. This cancellation policy supersedes all prior published information.
