Which of the following items is included in the enclosure testing report to the AHJ?

• A. Explanation of technical judgement; Test equipment calibration report; Test witness names; All of the above.
• B. Explanation of technical judgement.
• C. Test equipment calibration report.
• D. Test witness names.

Answer: (A)

AHJ enclosure test reports require complete documentation that shows how results were obtained, equipment accuracy, and verification of the process. The explanation of technical judgement reveals how the tester interpreted results and applied the relevant standards, especially when data are not black and white. This helps the AHJ understand the reasoning behind conclusions rather than just seeing numbers. The test equipment calibration report proves that the measurement tools were calibrated to recognized standards and are traceable, so the measurements are credible and defensible. The test witness names provide accountability and transparency, showing that competent observers were present to verify that the test followed proper procedures. When all three elements are included, the report gives a clear, auditable record that supports safety determinations. That’s why including all of the above is the best answer.
