- You are required to perform some calculations, so you must bring a calculator.
- The exam is "closed book", however you are provided with a booklet of standard tables, charts, formulae and basic reference material.
- To quote from the standard: "Questions shall be of a practical nature, yet test the candidate on concepts and principles required to conduct machinery condition evaluations. The questions may involve the interpretation of charts and plots. Simple mathematical calculations may be required."
Re-examination
To quote the standard: "A candidate who fails to obtain the pass grade required for certification may be re-examined any number of times, provided that the re-examinations take place not sooner than 30 days after a previous examination. A certification body may use its discretion in allowing an earlier re-examination in the event that further training acceptable to the certification body concerned is undertaken. Candidates excluded for reasons of unethical behavior shall wait at least 12 months before reapplying.".

To quote the standard: "Designation of a person as Category I is not a prerequisite for certification as Category II. However, certification of a person as Category III and Category IV requires previous certification at the lower category. At each higher classification category, the breadth and depth of experience is expected to be greater than at the previous lower category.".
You may take the Category III course and exam if you have previously taken a vibration training course with a recognized training company. Please contact Mobius Institute for further details.
Period of validity
As per the standard, certification remains valid for five (5) years. You may take the exam again within the 5 year period, or you can provide evidence of continued activity and study in vibration analysis and your period of certification will be extended without examination.
Annual fees
As per the standard, annual fees are not charged in order to maintain the validity of your certification.
