Which of the following is NOT a type of testing mentioned in NFPA 72?

Verification testing is often a part of the overall process for ensuring that fire alarm systems meet design specifications and regulatory requirements, but it is not specifically outlined as a distinct testing type in NFPA 72.

In contrast, acceptance testing involves evaluating the system's performance to ensure it meets the necessary standards for operation when newly installed. Commissioning testing refers to the process of ensuring that all components of the system work together effectively after installation. Re-acceptance testing is performed to verify that the system continues to perform as expected after modifications or repairs have been made. Each of these testing types plays a specific role in ensuring fire alarm systems are reliable and effective in protecting life and property.
