Students successfully completing this course are familiar with the scope and limitations of Airborne/Structure Borne Ultrasonic Inspection, are able to set up and calibrate equipment, interpret and evaluate results with respect to applicable codes, standards, and specifications, and organize and report inspection results.

Course content:
• Advanced Theory of
     Airborne/Structure Borne Ultrasound
     Compressed Gas Leaks
     Electrical
     Mechanical
         Valves
         Steam Traps
         Bearings
         Lubrication
• Advanced Inspection Logistics
• Condition Monitoring Principals
• Best Practices of Data Collection
• Data and Sound Analysis
• Writing and Establishing Procedures
• Program Implementation
• Generating Reports
• A General, Specific, and Practical 60 question exam is given at the end of the course.


Requirements for Level II Certification

In order to achieve an official certification, one must attend certification training (32 hours of classroom training) and must pass the General, Specific and Practical examinations with a combined score of 80% or better. Documentation of education or experience must be maintained annually. Hearing acuity must meet the minimum requirement of one ear of less than 25 dBHL at 500 Hz to 4 kHz (with or without aid.) Hearing acuity examinations must be documented annually. Documented experience signed by a supervisor or superior for 6 months additionally of the Level I experience of 6 months, for a cumulative 12 months’ experience to qualify for official certification of Level II.
