For a line tightness test, what is a common test parameter?

• A. The allowable pressure drop or leak rate over a defined time for the piping segment.
• B. The total volume of liquid in the tank.
• C. Ambient humidity during test.
• D. The color of the test medium.

Answer: (A)

Line tightness testing centers on detecting leaks by measuring how pressure changes in a segment over time. A common test parameter is the allowable pressure drop or leak rate over a defined time for the piping segment. This threshold defines pass/fail: if the pressure drop stays within the specified limit (or the leak rate stays below it) during the test period, the segment is considered tight. Other factors like the total volume of liquid in the tank, ambient humidity, or the color of the test medium don’t serve as the standard metric for leak detection in tightness testing.
