Gas piping systems in excess of 1,000,000 BTU input shall be tested for a maximum of how many hours?

Gas piping systems in excess of 1,000,000 BTU input shall be tested for a maximum of how many hours?

• A. 12 hours
• B. 24 hours
• C. 48 hours
• D. 72 hours

Answer: (B)

The test duration for gas piping systems with an input greater than 1,000,000 BTU is limited to 24 hours. This upper limit keeps the test practical and ensures leaks can be detected within a reasonable time without dragging on. A shorter duration, like 12 hours, is still within the cap and not the maximum. Longer durations, such as 48 or 72 hours, would exceed the allowed maximum and aren’t permitted.
