What is a key goal of functional testing in maintenance?

Functional testing during maintenance is aimed at verifying that equipment operates correctly according to its design specifications. This process involves running the equipment under normal operating conditions and assessing whether it performs its intended functions reliably and efficiently.

By ensuring that all components are working properly, functional testing helps identify any discrepancies that may have developed over time, thereby confirming that the equipment meets operational standards before it is returned to service. This process is essential for maintaining equipment reliability and safety, as well as optimizing performance.

In contrast, while determining if maintenance is needed, reducing repair frequency, and extending the life of equipment are important aspects of maintenance, they do not specifically address the immediate goal of assessing operational functionality. Instead, those objectives could be seen as benefits that arise from effective functional testing rather than its primary aim.
