The category III vibration course meets and exceeds requirements of ISO 18436-2. It is intended for students who have passed Cat II and wish to delve deeper into vibration analysis or manage CM programs. Students will be able to specify vibration monitoring equipment, establish condition monitoring programs and set acceptance testing criteria. Students will be able to conduct advanced analysis of both steady state and transient vibration data, conduct 2 Plane in-situ balancing and recommend other CM technologies.
