What is the purpose of using reference standards in ET?

• A. To calibrate instruments and verify testing accuracy
• B. To simplify the inspection process
• C. To promote quicker defect identification
• D. To enhance technician training

Answer: (A)

The purpose of using reference standards in eddy current testing (ET) is primarily to calibrate instruments and verify testing accuracy. Reference standards provide a known response that can be used to set the baseline for inspections. This is essential because it allows technicians to ensure that the equipment they are using is functioning correctly and providing accurate measurements. By comparing the readings obtained from the test piece against those from the reference standards, one can assess the performance of the testing equipment and make necessary adjustments to maintain precision. Using reference standards is critical for maintaining consistency in testing and enabling reliable defect detection. Without these standards, the validity of the readings could be compromised, leading to potential misinterpretation of the data obtained during inspections.
