Which of the following is a test or inspection to be performed?

The key idea here is verifying leakage at connection points. A joint tightness test is a straightforward check of whether all joints, flanges, or threaded connections are sealed properly and won’t leak under operating or test pressures. It’s a practical, routine inspection done during assembly and maintenance to confirm the system’s core seal integrity before putting it into service, especially when leaks could compromise safety or performance during re-entry operations. This makes it the best choice for a test or inspection to be performed, because it directly assesses the ability of the joints to hold pressure without leaks, which is fundamental to any pressurized system. The other options involve different kinds of checks: testing a valve seat is a specific, localized valve issue; a hydrostatic/pneumatic test is a broader, system-wide pressure test that isn’t always the routine inspection asked for in this context; and a system drop test checks something unrelated to leak-tightness.
