The correct answer is C. Performance test.

In PSP physical security system implementation, testing is used to verify whether security equipment and systems meet required performance requirements and success metrics. The ASIS PSP Body of Knowledge includes performance requirements, success metrics, commissioning, final acceptance testing, and life-cycle evaluation as part of physical security system design and implementation.

A performance test determines measurable operating parameters of the system or equipment. For intrusion detection sensors, these parameters can include probability of detection, false alarm rate, nuisance alarm rate, sensitivity, detection coverage, and other measurable performance characteristics. Sandia’s physical security testing guidance also identifies NAR/FAR — nuisance alarm rate/false alarm rate and probability of sensing as key sensor performance metrics collected from test results.

The other options are not the best answer:

A. Safety test focuses on whether testing or equipment creates unsafe conditions.

B. Evaluation test is broader and is used to validate overall PPS effectiveness, not mainly to determine specific parameters like nuisance alarm rate.

D. Post-maintenance test is conducted after maintenance to confirm the system still works properly.

Therefore, the correct answer is C. Performance test.
