Which party requires testing documentation for air sampling-type systems prior to acceptance testing?

• A. The AHJ
• B. Owner
• C. Manufacturer
• D. Third-party Inspector

Answer: (A)

The party that requires testing documentation before acceptance testing is the Authority Having Jurisdiction (AHJ). The AHJ enforces the applicable codes and standards and must review and approve the documentation—such as test plans, calibration data, commissioning records, and equipment lists—before acceptance testing can proceed. This ensures the air sampling–type system was designed, installed, and prepared for testing in compliance with the regulations. The owner may prepare and supply information and the manufacturer provides specifications and factory test data, but the formal requirement to have and review this documentation prior to acceptance testing rests with the AHJ. A third-party inspector can verify and sign off on tests, but they are not the gatekeeper for pre-acceptance documentation.
