Which data are typically recorded in a tank tightness test log?

• A. Pressure readings over time showing stability or leakage.
• B. Tank color after test.
• C. Operator's coffee breaks.
• D. Weather conditions.

Answer: (A)

In a tank tightness test, the essential information is how pressure behaves over time to show whether the tank holds pressure or leaks. The log is built from pressure readings taken at regular intervals, with timestamps, capturing the starting pressure, any changes, and the final pressure. By looking at how stable the pressure remains or how quickly it decays, you can determine if there’s a leak and if the test passes according to the acceptance criteria. Other details like the tank color after the test don’t provide data about tightness, and things such as the operator’s coffee breaks or weather conditions aren’t part of the standard tightness assessment data. Environmental notes may be recorded separately if needed, but the core data for evaluating tightness are the pressure readings and their trend over time.
