Which test evaluates the hardware's ability to withstand pressure prior to service?

• A. Hydrostatic Test
• B. Functional Test
• C. Endurance Test
• D. Operational Readiness Test

Answer: (A)

Testing the hardware’s ability to withstand pressure before it enters service is hydrostatic testing. In this test, the system is filled with a fluid and pressurized to levels above normal operating pressure to check for leaks, weak joints, or any structural failures in tanks, pipes, and fittings. The goal is to confirm the equipment can safely handle the pressures it will experience in actual use, establishing integrity and leak-tightness before it goes into service.

Functional testing, by contrast, verifies that components operate as intended when commanded under normal conditions ( valves, pumps, sensors functioning correctly ), but it doesn’t primarily assess how the hardware handles overpressure. Endurance testing looks at how the system performs over long periods or many cycles to reveal fatigue or wear. Operational readiness testing evaluates overall preparedness and correct procedures for use in real scenarios, rather than specifically validating pressure tolerance.
