In reference to damper testing, what does a “pass” result signify?

• A. The damper closed but did not seal
• B. The damper functions as intended
• C. The damper requires maintenance
• D. The damper has been incorrectly installed

Answer: (B)

A "pass" result in damper testing signifies that the damper functions as intended. This means that it successfully meets the operational and performance criteria established by relevant standards, including those outlined by NFPA guidelines. A damper that passes the test should effectively close and seal off airflow when required, ensuring that it can provide the intended protection against fire and smoke, thus contributing to the overall safety of the building’s HVAC system. This outcome indicates that the damper is not only operational but is also capable of performing its critical function in maintaining compartmentalization of fire and smoke, essential for occupant safety and property protection. In contrast, other options reflect conditions that would not qualify as successful results; for instance, if the damper closed but did not seal, required maintenance, or was incorrectly installed, the functionality would be compromised, and these outcomes would not warrant a passing result.
