In a pneumatic circuit, which of the following tests is not typically performed on a fluid power component?

• A. Inspecting the O-rings for wear
• B. Leakage test
• C. Pressure test
• D. Flow rate test

Answer: (A)

Testing focuses on verifying how a component performs under operating conditions. Leakage, pressure, and flow-rate tests are classic ways to confirm that a fluid power part seals properly, can withstand the intended pressure, and can deliver the required air flow. Inspecting the O-rings for wear, while important for maintenance, is a condition check rather than a performance test—it tells you about the seal’s state, not whether the component meets its functional specifications under pressure and flow. Thus, inspecting O-rings for wear is not typically considered a test of the component in a pneumatic circuit.
