What are test data sheets, and what data should they capture?

• A. Maintenance schedules.
• B. Warranty information.
• C. Documents recording test results; include test name, conditions, readings, pass/fail, and observations.
• D. Financial statements.

Answer: (C)

Test data sheets are records used during commissioning to capture the results of tests conducted on equipment and systems. They provide a traceable account of how a system performs under defined conditions and serve as a reference for verification and future maintenance. The data they should capture include the test name or objective, the conditions under which the test was performed (such as environment, system operating mode, and setpoints), the actual readings or measurements (with units and any relevant tolerances), the pass/fail outcome based on the criteria established for the test, and observations or notes that describe any anomalies, unusual behavior, or actions taken. Including who performed the test, the date, the instrumentation used (and its calibration status), and any required corrective actions helps ensure traceability and accountability for the commissioning process. This combination of organized measurements, outcomes, and context makes test data sheets essential for validating system performance and supporting future reference.
