Which items are typically documented to report UT inspection results?

• A. Instrument settings
• B. Calibration data
• C. Scan plan and area
• D. All of the above

Answer: (D)

All of these items are typically documented because UT results must be traceable, repeatable, and interpretable. Instrument settings capture the parameters used during testing—probe frequency, gain, dynamic range, pulse/receiver settings, coupling mode, and scan speed—which directly influence signal response and how indications are read. Calibration data record how the instrument was calibrated against reference standards or blocks, including sensitivity and baseline responses, so reported indications can be sized and evaluated against acceptance criteria. Scan plan and area describe exactly where and how the inspection was performed—the regions scanned, the path or pattern, orientation, and coverage—so findings can be located, the inspection scope verified, and any missed areas identified. When these elements are included together, the report provides clear traceability, enables reproducibility by another inspector, and supports reliable interpretation and decisions.
